Aluminum Nitride(AlN)
Aluminum Nitride(AlN) is a covalent bond compound, atomic crystal, a diamond-like nitrate, hexagonal crystal system, non-toxin, white or gray white, theoretic bulk density 3.26g/cm3. |
|
AlN ceramic has following properties: | |
(1)High thermal conductivity (theoretic value 320W/m.K) (2)High electricity resistance (3)Low coefficient of heat expansion(4.5X10-6ºC)Good march with Si(3.5~4×10-6ºC) and GaAs(6×10-6ºC) (4)Excellent electricity properties(Dielectric constant, dielectric loss, bulk resistivity, dielectric strength). (5)Good mechanic properties (6)Excellent corrosion resistance (7) Good optical transmission property |
AlN ceramic has become an ideal material for heat radiation and package in industries of large scale IC, semiconductor module, high power IC and high power components, been widely utilized in HBLED, UVLED, high power IC, power module, RF/microwave communication,automotive,microelectronic semiconductor, image transmission. |
