AlN Manufacturer Multi-Protruding disc Aluminum nitride ceramic substrate

Aluminium Nitride (AlN) - high Thermal Conductivity & Electrical Insulation Capacity.

Aluminum Nitride has high thermal conductivity and electrical insulation properties, and is used for heat dissipation or heat uniformity parts, such as those found in semiconductor processing equipment.

	Chemical formula for aluminium nitride:
	Aluminium nitride has the chemical formula AlN and the chemical composition AI 65.81%, N 34.19%. Its powder is white or off-white, single crystal colourless and transparent, sublimation decomposition temperature at atmospheric pressure is 2450℃.

	Aluminium nitride ceramic thermal conductivity:
	The thermal conductivity of aluminium nitride polycrystalline material is 70~210 W / (m.k), and the single crystal can be as high as 275 W / (m.k) or more, which is 5 times of alumina.

	Aluminium nitride ceramic substrates:
	High thermal conductivity, low coefficient of expansion, high strength, high temperature resistance, chemical corrosion resistance, high resistivity, low dielectric loss, is the ideal large-scale integrated circuit heat dissipation substrate and packaging materials.

Properties of aluminium nitride:

High thermal conductivity (>170W/m-K), close to BeO and SiC, more than 5 times that of Al2O3; Thermal expansion coefficient matches Si and GaAs; Excellent various electrical properties (dielectric constant, dielectric loss, body resistivity, dielectric strength); Good mechanical properties, higher flexural strength than Al2O3 and BeO ceramics, can be sintered at atmospheric pressure; Can be made by casting process. It is a promising substrate and packaging material for high power integrated circuits.
