AlN/ZrO2 and Others
Description
-
AlN (Aluminium Nitride)
Aluminum Nitride (AlN) has flexural strength of 300MPa, similar to alumina, thermal conductivity of 170~200W/mK, 10 times higher than alumina, and coefficient of thermal expansion of 4.2ppm/℃, similar to silicon.
Such unique properties are increasing its application to the thermal emission substrates of power module, illuminators requiring high output of over 8W, and automobile head lamps

ZrO2 (Zirconium Dioxide, Zirconia)
In general Zirconia is another name of Zirconium dioxide. Zirconium dioxide is a kind of Fine Ceramics and a white crystalloid oxide of Zirconium. It is a ceramic material closest to metal and with the excellent mechanical properties it is in the spot-light as a material to replace metal
