Product Description
Product introduction:
The structure and composition of aluminum nitride AIN ceramics are mainly with aluminum nitride (AIN) as the main crystal phase. Chemical composition: AI 65.81%, N 34.19%, specific gravity 3.261g/cm3, white or off-white, colorless and transparent single crystal, sublimation decomposition temperature under normal pressure is 2450°C. Thermal expansion coefficient (4.0-6.0) X10-6/ºC, capable of withstanding extreme heat of 2200ºC.
Features:
Good machinability and oxidation resistance. It has the characteristics of not being corroded by molten aluminum, other molten metals and arsenide, and especially has excellent corrosion resistance to molten aluminum. Stable to acids, but easily corroded in alkaline solutions.
Application:
1. Can be used as crucible and firing mold materials for smelting aluminum, copper, silver, lead and other metals.
2. As the base material of semiconductor
3. Used as heat sink and insulating thermal substrate for semiconductor devices to improve heat dissipation capacity and packaging density of substrate material. It can be used in dual in-line packaging and flat packaging.
4. Made into high-frequency piezoelectric components, large scale integrated circuit substrates, etc., such as used on ceramic substrates such as LED lighting.
