2) The maximum use temperature of alumina/silicon carbide microporous ceramics is about 1000 ° C, and the maximum use temperature is also related to size and shape. Still, if glue is stuck, it can only be lower than 100 ° C.
3) Microporous ceramics generally do not mention the roughness problem, because there are micropores, but the surface smoothness is similar to Ra0.8 of dense ceramics.
4) Low thermal conductivity. Only dense materials will have high thermal conductivity.
5) Microporous ceramics cannot be used in a humid environment or come into contact with conductive liquids. Otherwise, they will not be insulated.

Boron Nitride Molten Metal Atomizing Nozzles

Boron Nitride ceramic is a kind of refractory ceramic with low expansion and high thermal conductivity. This makes it to be an ideal choice to molten metals. It’s effortless to be machined to custom design with precision and tight tolerance because of its machinability.

Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100 °C. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from 1000 degree-furnace and cooling it within short minutes. It still won’t break even repeat this test 100 times.

The dimension of this BN metal atomizing Nozzles, Outer diameter: 13.9mm, Height: 13.75mm

Boron Nitride nozzle is often used in metal process for metal atomizing including various precious metal like gold, platinum, silver, etc

How are advanced ceramic components made?

Advanced technical ceramics are generally produced on a relatively small scale. Expensive raw materials are used, but these are compensated for with the resultant improved properties and consistency.

The important processing of advanced ceramic components are produced by sintering (firing) compacted ceramic powder (raw material) forming. The form components are usually referred to as ‘green-state’ and numerous powder-forming processes have been developed including dry pressing, hot pressing, isostatic pressing (CIP and HIP), injection, slip casting and extrusion. However, the powder consists of solid, hard, brittle particulates, so it is difficult to consolidate in a die by pressure alone. A binder is usually added to enhance the flow properties of the powder, leading to higher density in the final component. The binders used vary according to the process to be used and the desired properties of the final product.

Once the ceramic powders have been compacted to produce the green-state component, they are approximately 50-70% dense. They are also relatively weak, but with care can be machined to quite complex geometries. To impart strength, the green state components are usually sintered.

Initial heating (up to 250°C) volatilizes any organic processing additives (binders) and decomposable constituents. As the temperature increases to the firing temperature, consolidation, or sintering of the ceramic powders (solid-state sintering) begins and is usually accompanied by shrinkage. This shrinkage must be accounted (designed) for when machining in the green-state.

Sintering can be assisted (decreasing temperature or time requirements) by the deliberate addition of additives which will react to produce lower melting point green-state been (liquid phase sintering). These secondary phases can be envisaged as “gluing” the ceramic particles together. This is the case for ceramics such as alumina. Sometimes, sintering aids are added to enhance diffusion (which aids sintering), this is the case when additions of boron or aluminum are added to hot-pressed silicon carbide.

A general flow diagram for ceramic processing is shown as linked.

How To Make Technical Ceramic Part By Low Injection Way – From Innovacera

1. Compounding Ingredient
Weigh and mix raw material powder in a certain proportion. In order to guarantee the quality from the first step, we do this step itself instead of buying already-mixed raw material.

2. Drying
Remove the moisture from raw material. Make sure the hardness of the finished product.

3. Ball-milling
Mixing the material while grinding by ball milling machine. The purpose of this step is to reduce the grain size of the powder and to make it fully mixed.

4. Sieving
Sieve to remove the impurity in the powder & dry it. (After this step, the grain size will be tested.)

5. Wax Placing
Heat solid wax into thick liquid. Add the powder and mix them up. Wax helps the ceramic raw powder to shape up. Then pour the mixture into a container, making it cool down and solidify into a solid block in the air.

6. Melting
The mixture solid is preheated to be slightly soft for easier transfer. The mixture is turned into a liquid at 90 ° C, and vacuum is applied. The purpose of vacuuming is to drive away air bubbles in the liquid and mix the slurry evenly. (The viscosity of the raw material will be tested after this step)

7. Forming
Keep the material in low injection machine under 65-70℃, to ensure the material does not solidify. Material is squeezed out from the machine into mold. It will shape up and harden when contacting air. (Mould are placed on ice blocks in order to cool them down. And the air blowing is to dry the mold.)

8. De-waxing and Glue Removing
Put the shaped-up product in the low-temperature room. After standing for a few days, it is sufficiently cooled and hardened, and then transferred to a crucible containing β-Al2O3 powder (the β-Al2O3 powder has an adsorption function, which can adsorb and remove wax or other glue which helps to form, and can be recycled). Then, it is placed in a medium temperature furnace at 1100 ° C for 53 hours, and the wax and glue removing is done after taking out the packaging. The finished product after this step is called pottery.

9. Sintering
Put the product on the setters (the bearing plate requires high-temperature resistance, the temperature should be around 1700 °C), into the high-temperature furnace calcine for 24 Hours (temperature is around 1650-1700 °C, depending on different material requirements), the finished product after this step is called ceramic. Tolerances of finished product are between ±0.1. The high-temperature furnace including a box furnace and a tunnel furnace. The tunnel furnace consumes a large amount of electricity and has a high cost, and is suitable for burning large quantities of products.

10. Cleaning
Firstly use ceramic beads to polish and rub the finished product to remove burrs and make the surface smooth. If there is no special requirement, usually the products are ultrasonically cleaned. Then products can be packed up and ship to our customers. If there are special requirements, the first step is also polished & rubbed through ceramic beads, and then do machine process in due course.

11. Machine
Machine processes include surface grinding, internal/external grinding. The internal grinding machine has a maximum grinding diameter of 100mm and a maximum grinding depth of 150mm. It is mainly achieved by the friction between the grinding wheel and the machining part. The precision can be up to 3μm. (The grinding wheel has different models. different grinding wheels for different precision.)

12.Inspection Equipment
a. Two-dimensional detector (detecting the appearance and size of the product);
b. Roughness detector;
c. Density detector;
d. Viscosity detector;
e. Bending and tensile strength tester;
f. Vickers hardness tester;
g. Laser particle size analyzer;
h. Manual inspection.
