High Purity Aluminum Nitride AlN Ceramic Microsphere, 99.5% | Lemondedudroit

AlN’s thermal conductivity is high and it can also be used to insulate electrical circuits. You can increase thermal conductivity by adding AlN powder to your resin.


AlN Ceramic Microsphere – Aluminum Nitride AlN


Aluminum Nitride

Non-oxide ceramic material primarily composed of aluminum, nitrogen (AL-65.71%, N-34.19).

Aluminum Nitride

Formula chemical



Ceramic Microsphere

Has high thermal conductivity (340W) as well as heat transfer performance, after secondary laser melting alloying. The heat preservation effect and thermal conductivity effect are very evident due to the low oxygen content at lt.0.1%. Viscosity can be used as a thermal conductivity insulation material in polymer resin.


Spherical aluminum Nitride

It was synthesized for the first times in 1877. In the 1980s



Due to its heat transferability and high use in the microelectronics field, Microsphere is a Ceramic insulation. AlN Ceramic Microsphere does not contain any toxic elements, which is a big advantage over beryllium oxide. This ceramic spherical aluminium nitride can replace alumina or beryllium dioxide in many electronic instruments.

Spherical Ceramic


It can be made by adding carbon and aluminum oxide to reduce the material, as well as directly nitriding it with aluminum. This crystal has the hexagonal shape of zinc sulfide, and wurtzite. Hot pressing and welding are the only methods to make industrial-grade material. It is extremely stable when exposed to high temperatures.

How Aluminium Nitride AlN Ceramic Microsphere Is it Produced?

By laser flame melting, spheres made of aluminum nitride were created. High purity, consistent particle size distribution and clean surface are some of the benefits. They also have good compatibility with living organisms.

AlN Ceramic Microsphere

1. AlN Ceramic Microspheres are obtained by secondary laser melting and/or spherical alloying. The material has uniform sizes and fluidity which increases the material’s thermal conductivity, insulation, and heat resistance.

2. AlN Ceramic Microsphere surfaces are treated after melting with resistance to hydrolysis, oxidation and thermal conductivity.

3. The injection molding performance of ceramic spherical aluminiu nitride is excellent. It can be used to make composite materials.

4. Use in thermoconductive plastics. Modified AlN Ceramic Microscopic can significantly improve thermal conductivity. It’s currently used in PVC and polyurethane plastics as well as functional and functional plastics.

AlN Ceramic microsphere Storage Condition:

A damp reunion could affect aluminum-nitride’s ceramic microsphere performance. Therefore, an aluminum nitride(AlN), ceramic microsphere must be kept in vacuum packed and in a dry place. The aluminum nitride/AlN ceramic microsphere cannot be placed in direct sunlight. Additionally, stress should be avoided when handling the aluminum nitride(AlN) ceramic nanosphere.

Shipping and Packing of Aluminum Nitride AlN Ceramic Microspheres

Many types of packing are available depending on the amount of aluminum nitride or AlN ceramic microspheres.

AlN ceramic microsphere packing for aluminum nitride: vacuum Packing, 100g to 500g, 1kg/bag and 25kg/barrel. Or as you request.
