High Purity Aluminum Nitride AlN Ceramic Microsphere, 99.5%

AlN is a good thermal conductor and can even be used in insulation for electrical circuits. You can significantly improve thermal conductivity by using AlN powder.


AlN Ceramic Microsphere, Aluminum Nitride AlN


Aluminum Nitride

A non-oxide ceramic material made primarily of aluminum and nitrogen (AL-65.71%,N-34.19).

Aluminum Nitride

Formula chemical



Ceramic Microsphere

High thermal conductivity of 340W and heat transfer performance after secondary laser melting alloying. Low oxygen levels at lt.0.1% make it very effective in heat preservation as well as thermal conductivity. In polymer resins, viscosity is used to insulate thermal conductivity.


Aluminium Nitride in Spherical Form

It was synthesized in its first form in 1877.



Microsphere, due to its high heat transferability and use in microelectronics is considered a Ceramic insulation. AlN Ceramic Microsphere has no toxic elements. That’s a huge advantage over berylliumoxid. The ceramic spherical alm nitride, which is ceramic-spherical in shape, can be used to replace alumina and beryllium dioxide in many electronic instruments.

Spherical Ceramic


This can be done by adding carbon or aluminum oxide to reduce it, as well direct nitriding with aluminum. This crystal has the hexagonal structure of zinc sulfide. The only way to produce industrial-grade material is by hot pressing or welding. This material is stable even when heated.

How AlN Clay Microsphere Does it Get Produced?

Spherical aluminum-nitride (or spherical) clays can be made by laser flame melting. The benefits include high purity, uniform distribution of particle sizes and a clean surface. The particles can also be used in conjunction with living organisms.

AlN Ceramic Microsphere

1. AlN Ceramic Microspheres can be made by secondary laser melting, spherical alloying and/or secondary laser melting. Material’s thermal conductivity and insulation are increased by the uniform size and fluidity.

2. AlN Ceramic Microsphere Surfaces are treated with resistance to hydrolysis. Oxidation, thermal conductivity and heat.

3. It is very easy to mold ceramic spherical metal. Composite materials can be made from it.

4. You can use it in thermoconductive plastics. The thermal conductivity of modified AlN Ceramic Microscopic is significantly increased by using it. It is used in PVC, polyurethane and other plastics.

AlN Ceramic Microsphere Storage Conditions:

The ceramic microsphere performance in aluminum-nitride could be affected by a damp reunion. A ceramic microsphere made of aluminum nitride, (AlN), must be kept dry and vacuum packed. It is not recommended to expose the ceramic microsphere of aluminum nitride/AlN to sunlight. The aluminum nitride/AlN ceramic micrsphere should not be handled in direct sunlight.

Transportation and Packaging of Aluminium Nitride AlN ceramic Microspheres
