Silicon Nitride Ceramic Weld Location Pins for use in Resistance Welding

Innovacera manufactures Silicon Nitride (Si3N4) Ceramic weld location and control pins for use in resistance welding. These are used in the metal forming industry to allow precise welding of nuts to sheet metal.

Due to ceramic’s high hardness and durability, metal can’t compete with it in insulating properties, resistance to temperature changes, and minimal wear. Another advantage of using ceramics as centering pins is their smooth polished surface, which prevents welding spatter from adhering. However, when welding pins made of commonly used zirconia ceramics, the service life does face a limit. This material also cannot withstand the currents in projection welding and the required 800°C operating temperature over time, so it wears out. And centering standard molds made of silicon nitride ceramic is a good choice.

Silicon nitride ceramic weld location pins have the following advantages:
1.High-temperature stability: Silicon nitride ceramics can maintain stability in high-temperature environments, have excellent heat resistance, and can withstand thermal stress and thermal cycles during high-temperature soldering.
2.Corrosion resistance: Silicon nitride ceramics have excellent corrosion resistance to common corrosive media such as acid and alkali.
3.High hardness and wear resistance: Silicon nitride ceramics have high hardness and wear resistance, which can keep their shape and geometry stable for a long time during the welding process.
4.High precision: Silicon nitride ceramics have excellent dimensional and mechanical stability and are suitable for applications requiring high-precision positioning in welding processes.
Therefore, silicon nitride ceramic welding location pins are an ideal material for positioning and support needs during welding.

Ceramic Heater Used For Vaporizer

Innovacera developed ceramic heating element used for vaporizer.
The most common heating elements in a vape are made from metal, glass and ceramic. What are their differences? Which is better to be used for vaporizer?

Metal heating elements conduct heat quickly, so they heat fast and adapt well to temperature changes. However, some metal heating elements can infuse vapor with metal particles. Inhaling these particles can damage the lungs and may be dangerous. So metal heating elements is not a good choice for vaporizer.
Glass is not a favored option. As glass is too delicate for an entire portable vaporizer. It’s also far more expensive than ceramic, and without any additional benefits.
Ceramic heating elements are considered the highest quality for vaporizers. First, ceramic is considered the safest heating method for vaporizers since they do not carry metal particles into the vapor. Our ceramic heater material is with Rohs and Reach certification.

The Advantages of ceramic heater:
1. Small size;
2. Fast heating rate;
3. More uniform thermal performance, and thermal efficiency;
4. To integrate with thermistor, so as to achieve the purpose of accurate temperature control;
5. Safety

Guide to Designing with Advanced Technical Ceramics

Often an engineer unfamiliar with using ceramics will want a direct copy of a component that was originally metal, for example, made in ceramic. Very often this is not the best solution and can unnecessarily increase manufacturing costs and even result in the component not working as desired.

By following these suggestions where possible, the advanced ceramic part will be easier and cheaper to make, saving you time and money, while still delivering a part ‘fit for purpose’.
1. Tolerance dimensions as loosely as possible. If a component can be toleranced at ± 1-3% for example, the part can usually be produced ‘as-sintered’. This then eliminates the need to diamond grind the component, which is one of the most costly stages of manufacture.
2. Avoid features that cause stress concentrations, such as sharp edges and corners, sudden changes in cross-sectional area, and small contact points. Sharp edges and corners should be relieved by chamfers, radii, or undercuts. If possible use tapers to gradually change the cross-sectional area. Provide large contact areas to spread the load.
3. Keep the component form as simple as possible. Ceramic components are fabricated by first forming a low density ‘green’ compact, which is subsequently sintered to full density. This results in shrinkages of up to 30%, which for complicated shapes makes tight dimensional control difficult. In some cases, it may be advantageous to change the form of a non-ceramic part of the design in order to simplify the ceramic component. Alternatively, consider using a modular design, that is, split the component into several smaller, simpler pieces.
4. Keep section or wall thickness as uniform as possible. Large changes in component thickness are another cause of stress concentrations. This can be the case when holes are located off-center, for example. Also, a thin section will densify quicker than a thick section and so warpage or grain growth could occur while the thicker section is still densifying. Grain growth can result in a reduction in strength and should where possible be avoided.
5. Avoid unnecessary diamond grinding. Grinding can cause very high-stress concentrations, which as mentioned above, can cause flaws. However, by optimizing the grinding parameters or by polishing or lapping, this problem can be minimized.
Hopefully, these design tips will give you some points to consider when attempting to incorporate advanced technical ceramics, such as alumian, zirconia, , in your design. Should you need more information, please contact one of our engineering staff or see our materials section for more information on the fine ceramics we manufacture.

Precautions for cleaning and sterilizing alumina ceramic filling pump

Cleaning steps: Clean with purified water, and then rinse with purified water;
Soak the ceramic pump with 1-3%NAOH for 5-15 minutes, which is equivalent to pyrogen removal, and then rinse with injected water.
Sterilization steps: Use high-pressure humid heat steam for sterilization. The sterilization temperature is 121℃, the pressure is 0.1MPA, and the time is 30 minutes (recommended time).

Precautions for cleaning and sterilization:
(I)shall not use fluorine containing chemical solution and stainless steel war, to prevent corrosion of stainless steel parts; When washing, do not pull the ceramic column or plug of the ceramic metering component in the hot water higher than 40℃. The ceramic plug should be removed for washing. Ceramic rod and ceramic plug cannot be exchanged during the washing process; During sterilization, the rotary valve, ceramic plug and metering rod should be placed away in the special washing sterilization box, and the ceramic rod and ceramic plug should be vertically hung for humid heat sterilization; After sterilization, the pump body temperature should be reduced to room temperature before placement operation; Before the pump body temperature drops to room temperature, it should refrain from sudden cooling resulting in pump body cracking and deformation.
(II) If there is yellow dirt in the ceramic pump body and the liquid part, it can be soaked in 10% oxalic acid for 0.5-1 hours, and then washed with water for injection; Because the hardness of ceramic is greater than stainless steel, ceramic and stainless steel war can make the ceramic appearance adhesion to stainless steel, can not be processed clean, probably lead to the filling pump is not smooth or can not move, resulting in damage. Initiate washing and sterilization using non-metallic materials (such as tetrafluoroethylene) as storage containers; When the plunger sleeve, plunger, and slot valve are removed from the mechanical preparation, please put the plunger sleeve vertically, and the plunger slot valve is tied with a rope in the air vertically by gravity to prevent deformation.

Boron nitride components for MOCVD

Hot-pressed hexagonal Boron Nitride is often referred to as “white graphite” since it has similar layer structure as graphite. It has outstanding thermal characteristics: high thermal conductivity and excellent thermal shock resistance. It is stable up to 2000 °C in reducing atmospheres, and up to 900 °C in oxidizing atmospheres. It has features such as highly machinable, low thermal expansion, microwave transparency and high wet resistance to molten metals, slags and glass. Boron nitride ceramic parts are widely used as PVD, MOCVD, MBE system, furnace components, melting crucibles, insulators, washers, nozzles, microwave tubes, heat sink and heat radiation shielding.

An MOCVD reactor is a chamber made of a material that does not react with the chemicals being used. It must also withstand high temperatures. This chamber is composed of reactor walls, a liner, a susceptor, gas injection units, and temperature control units.
In the MOCVD reactor, the substrate is supported by a pedestal, which also acts as a susceptor. The pedestal/susceptor is the primary origin of heat energy in the reaction chamber. Only the susceptor is heated, so gases do not react before they reach the hot wafer surface. The reaction chamber walls in a cold-wall reactor, however, may be indirectly heated by heat radiating from the hot pedestal/susceptor, but will remain cooler than the pedestal/susceptor and the substrate the pedestal/susceptor supports. So Boron Nitride is a good choice because the power density, operating temperature, insulation grade and dielectric strength of heating elements can be greatly improved by using Boron Nitride as an insulator. It is also more economical and reduces thermal inertia. The annular shape reduces the size of the heating system and improves heat transfer.

What should I pay attention to when I use Boron Nitride products?
1. Keep BN products in vacuum package before usage.
2. After vacuum package is removed, store BN products in dry and cool environment. Keep container tightly closed while not in use.
3. BN products are brittle. Please handle with care.

The difference between boron nitride crucible and alumina crucible

As an important part of chemical equipment, crucible is a container for melting and refining liquid metal and heating solid-liquid reaction. It is the basis for ensuring the smooth progress of chemical reactions.
There are many types of crucibles. According to the raw materials, ceramic crucibles can be divided into boron nitride crucibles, alumina crucibles, zirconia crucibles, aluminum nitride crucibles, quartz crucibles, etc. Here we mainly introduce the difference between boron nitride crucibles and alumina crucibles.
The advantages of boron nitride ceramics crucible compared to alumina ceramics crucible are:

1.The temperature is high, and the long-term use temperature of boron nitride under vacuum is 1800 degrees, and the long-term use of 2100 degrees under the protection of the atmosphere. Alumina does not exceed 1700 degrees.
2.Strong thermal shock resistance, rapid cooling and no cracking. The boron nitride ceramics are taken out of the 1000 degrees furnace and quenched by the air blower, and will not crack even if repeated 100 times.
3.It is resistant to acid and alkali corrosion, has strong electrical insulation, and has a resistance to electrical breakdown of 3 to 4 times that of alumina.
4.Boron nitride ceramics do not react with many metals, ceramics, rare earth and other materials. Such as ferrous metal, iron, copper, stainless steel, tantalum, aluminum, tin, chromium, lead, nickel, magnesium, etc., glass melt, soda glass, cryolite, etc., silicon lava: slag, fluoride and the like. It can be used as a container, enamel, setter, etc.
The disadvantages of boron nitride ceramics crucible compared to alumina ceramics crucible are:

1.Boron nitride ceramics have lower strength, hardness and wear resistance than alumina, and are not suitable for use in vibration and friction environments.
2.Boron nitride ceramics should not be used in the air at temperatures exceeding 1000 degrees. Exceeding oxidation, boron nitride can only be used up to 2000 degrees under vacuum or atmosphere protection.
