After confirming the dye penetrant test is qualified, then Innovacera arranges to clean the ceramic ball valves.

ALN – An Insulation High Thermal Conductivity Material

Aluminum Nitride is one of the function ceramics among all the advanced ceramics. It has very good thermal-mechanical and electrical properties: high thermal conductivity, low dielectric constant, the linear expansion coefficient matches well with silicon, good electrical insulation, low density, non-toxic, high mechanical strength, and so on. with the fast development of microelectronics, the high T/C AIN used as the base or package material has been put on more and more focus.

With the development of the electric components, smaller but better performance and lower energy cost elements are of pressing demand. The high dense, high power, and high frequency component may generate as much as 100W/cm² heat, such as High bright LED, MOSFET, IGBT, and laser elements. The longer those elements work, the more heat accumulated. Due to the limited room in the package, if the heat could not have been diffused in time, it would highly affect the elements’ life, performance, and reliability. So, it is important to introduce a good cooling package design and high thermal conductivity ceramic materials into these industries.

Innovacera has 4 main products: AlN substrate, AlN Structural parts, AlN dry pressed tablets, Isostatic pressed parts, and so on.

Ceramic Igniters For Solid Fuel Furnaces

Our special application area for high-temperature heaters is in heating systems that use solid fuels such as wood pellets as the energy source. The challenge here is to ignite the biomass in a very short time while retaining very low emission values. This can only be achieved with a sufficiently high ignition temperature.

Our short surface ceramic igniters are perfectly suited for this purpose. The special geometry of the cylindrical ceramic heaters, in combination with an extremely high surface temperature of 1000°C, heats up the supply of air in the shortest possible time to an extremely high temperature. After a maximum of 90 seconds, the fuel is ignited with a fraction of the energy that is required for a hot air ignition blower. This works, of course, not only with pellets but also with wood chips, firewood, coal bricks or other solid fuels made of biomass.

Further product advantages:

1. Ready assembled, easy-to-install systems
2. Space-saving, noiseless and impervious to overheating (in case the blower fails)

Extremely long-lasting and resilient
Minimal energy consumption
Completely electrically insulated
No exposed electrical contacts
No sensitive welding points

Not without reason, the high-temperature heating elements pellet igniter is the reliable standard ignition system for pellet heating systems in Europe-hundreds of satisfied customers speak for themselves.

How to make Pyrolytic Boron Nitride Ceramic Part?

Innovacera PBN ceramic part includes the PBN Disc, PBN Sheet, PBN Filament Ring, PBN VGF Crucibles, PBN LEC Crucibles, PBN MBE Crucibles, PBN Conical Crucible, and Other PBN Machined Custom Parts.

PBN is a grade of hexagonal boron nitride. It is made by a chemical vapor deposition process to create its robust body, and all the boron nitride crystals grow parallel to the surface of which the vapor is deposited. Due to the nature of the CVD process, the PBN products generally request the product; thick wall products are not more than 3mm. PBN is also the right choice for extremely high purity boron nitride. As the purity of gas material (BCl3 + NH3 –> BN +HCl) is a lot higher than regular boron nitride powder, purity for PBN is quite high, and 99.99% is the average grade. With its high purity, high mechanical strength, high performance with molten metal, and salts, PBN is becoming a widely used material in high vacuum processes. Without showing melting point and high thermal conductivity, pyrolytic content is ideal to be used as a vacuum furnace part. The CVD process gives this PBN an almost perfect layered structure, which leads to anisotropic thermal conductivity, making it an ideal material to make crucibles for crystal growing.

Molecular beam epitaxy (MBE) is a standard process for gallium GaAs crystal production, and PBN is the ideal material to make MBE crucibles.

Innovacera Performance Pyrolytic boron nitride properties are as below:
Good thermal conductivity
High insulation resistance
High dielectric strength over wide temperature ranges
Extremely pure
Non-wetting
Non-toxic
Non-reactive to most other compounds
Withstand high temperatures and rapid cooling

PBN-PG Heater Performance and Applications

The PBN-PG ceramic heater combines three layers of ultra-high purity ceramics, PBN-PG-PBN to produce an advanced micro-ceramic heating element system. PBN as an insulating substrate and PG as the resistive element. Both our PBN heater (Pyrolytic Boron Nitride) and PG heater (Pyrolytic Graphite) are manufactured by high temperature CVD. These high performance elements exhibit outstanding thermal properties in a ceramic heater, including high thermal conductivity and anisotropy.
