High Thermal Conductivity Aluminum Nitride (AlN) Nanopowders

The Performance of Aluminum Nitride Nanopowders:

1. High thermal conductivity (about 320W / m ·K), close to the BeO and SiC, is more than five times of Al2O3;

2. Thermal expansion coefficient (4.5 × 10-6 ℃) and Si (3.5-4 × 10-6 ℃) and GaAs (6 × 10-6 ℃) match;

3. A variety of electrical properties (dielectricconstant, dielectric loss, the volume resistivity, dielectric strength)excellent;

Good

4. Mechanical properties, flexural strength thanAl2O3 and BeO ceramic, can pressure sintering;

5. Optical transmission characteristics of agood;

6. Non-toxic;

Application for Aluminum Nitrides Nanopowders:

1. Making integrated circuit board,electron device, optical element, and radiator. In high temperature crucible,to make metal matrix and high polymer matrix composites, especially in high temperature sealant and electronic packaging material, to enhance heat dispersion and strength.

2. Heat conducting silicon and thermalconductive epoxy resin.

3. Nano lubricant and antiwear agent.

4. High thermal conductive plastic.

5. In smelting non-ferrous metal andsemiconductor material gallium arsenide crucible, evaporation, thermocoupleprotecting tube, high-temperature insulation parts, microwave dielectricmaterials, thermal stability and corrosion resisting structural ceramic,transparent AlN microwave ceramic, etc.
