Aluminum Nitride powder Aug 10, 2009

The characteristic of Aluminum Nitride:
High thermal conductivity - About 10 times that of alumina, up to 220 W. These devices have high hardness,high modulus,very high dielectric properties,good oxidation-resistant property and low-thermal expansion efficient,which is approximate to that of Silicon . When the ALN powers is used to make composites its interface compatibleness is good . It can improve mechanical properties,thermal conductance and dielectric properties of composites .
Applications of Aluminum Nitride:
Circuit substrates ouch as f semiconductor modules and IC packages
Heat sink materials for power transistors,thyristors,LDs and LEDs
Crucibles for molten metals,vacuum deposition and preparing single crystals
Window materials for infrared and radar applications
