High Purity Aluminum Nitride AlN Ceramic Microsphere, 99.5%

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 Aluminum Nickel, a nonoxide ceramic material, is composed mainly of aluminum and nitrogen (AL-65.71%, N-34.19) AlN Ceramic Microsphere exhibits high thermal conductivity of 340W and excellent heat transfer properties after secondary laser melting alloying. The heat preservation effect and thermal conductivity effects are very evident due to the low oxygen level (lt.0.1%). Viscosity can be used as a thermal conductivity insulation material in polymer resin. Ceramic The first spherical aluminium nitride synthesized was in 1877. Due to its excellent heat transferability, AlN Ceramic Ceramic Microsphere has been used extensively in microelectronics research since the 1980s. AlN Ceramic Microsphere does not contain any toxic elements, which is a big advantage over beryllium oxide. The ceramic spherical aluminium nitride can be treated with aluminum and used in an array of electronic instruments as a replacement for beryllium and alumina. Spherical Ceramic AlN may be made by using carbon, aluminum oxide or direct nitriding of metal aluminum. This hexagonal crystal structure is the same as that of zinc sulfide, wurtzite and other metals. Hot pressing and welding are the only methods to make industrial-grade material. It is stable even in an environment of high temperature and inert.

How does Aluminum Nitride AlN Ceramic Microsphere get made? By laser flame melting, spherical aluminum-nitride clays were made. 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 aluminum is excellent. It can also be used to make composite materials. 4. Use in thermoconductive plastics. Modified AlN Ceramic Microscopic can significantly improve thermal conductivity. It’s currently being used in PVC and polyurethane plastics as well as functional plastics such as PP 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 not be applied to the aluminum-nitride(AlN) ceramicsphere.

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 or 1kg/bag. 25kg/barrel. Or as you request. Aluminium nitride, (AlN), ceramic microsphere shipping: will be shipped by sea, air or express, once the payment has been received.
