Boron Nitride Nozzle For Molten Metal Atomizing

BN is a material with the non-wet feature. So molten metal won’t be stuck onto the nozzle. Additionally, Boron Nitride ceramic is a kind of refractory ceramic with low expansion and high thermal conductivity. These features make it to be an ideal choice for atomizing nozzles. It’s very easy 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 a 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 temperatures.

We will keep to work closely with clients to help provide the qualified ceramic products to meet unique and demanding performance requirement in further 10, 15, 20, 25…years and never stop.

Silicon Nitride Ceramic Substrate for Electronics

INNOVACERA Silicon Nitride substrates, with a thermal conductivity rating of 90 Watts/meter Kelvin, at first glance, appear inferior to Aluminum Nitride grades from the standpoint of heat dissipation. However, Silicon Nitride substrates, due to their far superior mechanical properties, can provide thermal resistance levels comparable to Aluminum Nitride.

This is because Silicon Nitride substrates have twice the strength and fracture toughness of Aluminum Nitride substrates, which enable the circuit/package designer to use Silicon Nitride substrates that can be half as thick as Aluminum Nitride substrates.

These same impressive mechanical properties also make Silicon Nitride substrates an excellent choice in applications where severe, repetitive thermal cycling of the circuit/package is present.

Silicon Nitride Ceramic Thermocouple Protection Sheaths

INNOVACERA manufactures a range of silicon nitride ceramic and advanced ceramic thermocouple protection sheaths for use in the aluminium and molten metal handling industries. They are an advanced ceramic tube offering outstanding performance for temperature control in aluminium foundries and smelters and are extremely cost effective compared to competitive materials, such as cast iron, silicon carbide and alumina.

INNOVACERA silicon nitride possesses a unique combination of physical properties, such as high strength, toughness, excellent thermal shock resistance and resistance to corrosion, which make it the stand out material in this application.

Silicon nitride protection tubes are world renowned for their outstanding performance in contact with non-ferrous molten metals, particularly aluminium and its alloys and zinc. They allow constant temperature monitoring of the melt resulting in improved quality of the finished casting. In addition to its excellent physical properties, it is also non-wetting to most non-ferrous alloys, making it resistant to build up of dross and is therefore very low maintenance.

For high temperature applications above 1200°C, silicon nitride ceramic protection tubes are the preferred choice.

Senior engineers from Singapore visited Innovacera

Last week, senior engineers who is specialized in sealing from Singapore has visited INNOVACERA.

Together with our engineer look around the production process of ceramic products. From raw materials, moulding, sintering and precision machining, inspection is carried out at every step. Customers are very satisfied with the excellent performance and strict quality control of our production equipment. And she said that our raw materials are very good, 99% alumina density reach 3.9g/cm3. This led her to change some views of “Made in China”.

After that, we held a friendly meeting to discuss how to further cooperate. Innovacera pressed its willingness to invest in new projects in the future. Innovation is one of our core values, and we have always been enthusiastic about exploring in the professional field.

High precision silicon nitride balls, roller for bearing, pump valve

Silicon nitride (Si3N4) feature:

High strength, fracture toughness and erosion resistance for improved durability
Helps extend the life of sucker rod pumps, bearings
Withstands extreme temperatures of deepwater environments
Weighs 60% less than steel with significant friction reduction
Provides high contact fatigue resistance
Offers temperature resistance up to 1100°C

Required Properties and its Application examples

High speed: Machining tools: turbo chargers, HDD spindle motors
Corrosion resistant: Chemical plant equipment, semiconductor-manufacturing equipment
High temperature: Heat treatment furnace parts
High vacuum Turbo molecular pumps
High insulation: Electric motors
Ultra-low temperature: Turbo pumps for space shuttles

INNOVACERA silicon nitride materials and components are produced using unique compositions and processing techniques. INNOVACERA silicon nitride is processed by gas pressure sintering, which results in a fully dense and nonporous microstructure of interlocking needle-shaped grains. This, combined with the natural toughness of silicon nitride, provides outstanding contact fatigue resistance and mechanical reliability.

Silicon Nitride Ceramic Weld Location Pins

Ceramic materials have long replaced metal in the production of welding pins, which ensure a perfect fit for sheet metal and nuts in projection welding and are subject to temperatures of up to 800°C.

Gas-pressure sintered silicon nitride ceramics from INNOVACERA are at a distinct advantage here:
Extreme hardness and flexural strength
High thermal shock resistance
Electrical insulation
Temperature resistance
High tensile strength and compressive strength
Fewer cold welds
No welding spatter adhesion

Ceramic welding pins made of silicon nitride significantly increase service life and enable high levels of precision and greater accuracy over extended periods in projection welding. Metal welding pins often need to be replaced several times a day due to wear and adhering slag, whereas centring pins made of silicon nitride ceramic only need to be replaced about once a month.

Innovacera® Valveless ceramic metering piston pumps For H2O2

Innovacera provides advanced ceramic solutions for fluid dispensing and filling in the pharmaceutical, cosmetic and food industries. Our ceramic filling pumps types are valveless ceramic metering piston pumps and valve ceramic piston pump.

In pharmaceutical and medical applications, vaporized hydrogen peroxide is a low-temperature sterilization method used to decontaminate everything from components and instruments to entire laboratories, clean rooms, and hospital operating rooms.

Valveless ceramic metering piston pumps only have a ceramic piston moving part contacting with the fluid. The ceramic piston is made by alumina ceramic or zirconia ceramic which have chemically inert, wear-resistant, and dimensionally stable. IT accomplishes both the pumping and valving functions resulting in a unique design that eliminates all check valves. It also provides maintenance-free operation for millions of cycles, at a precision of 0.5% or better without the need for recalibration.

Hydrogen peroxide (H2O2) is used in many foods, pharmaceuticals, and medical applications as an effective sterilizing agent. Dispensing of H2O2 is critical to container sealing during the aseptic packaging process for a variety of food products.

According to the above advantages, Innovacera Valveless ceramic metering piston pumps are suitable for OEM sterilization equipment and it is widely used for hydrogen peroxide metering.

The Ideal Material of Thermal Management – Aluminum Nitride Ceramic Components

Aluminum Nitride Ceramic (AlN) is an ideal material widely used in situations that demand both high thermal conductivity and electrical insulation. This unique ability makes AIN ideal for managing rapid heating and removal of heat from other components and systems, such as in heat sinks, heat exchanger and spreaders.

In addition, its low coefficient of thermal expansion, which is similar to silicon material, means AIN is a trusted substance for use in semiconductor products. The material remains highly stable through a wide range of temperatures.
