Aluminum nitride is synthesized by carbothermal reduction of alumina or by direct nitridation of aluminum. Aluminum nitride density is 3.26g/cm3. Although it does not melt, it decomposes above 2500°C at atmospheric pressure.
Aluminum nitride is covalently bonded and can resist sintering without the help of liquid molding additives. In general, oxides such as Y2O3 or CaO allow sintering at temperatures between 1600 °C and 1900 °C.
Aluminum nitride Properties
AlN can resist the erosion of most molten metals, especially aluminum, lithium and copper.
It can resist the erosion of most molten salts, including chloride and cryolite.
High thermal conductivity of ceramic materials (second only to beryllium oxide).
High volume resistivity.
High dielectric strength.
It is eroded by acids and bases.
In powder form, it is easily hydrolyzed by water or moisture.
What is Aluminum nitride used for?
Aluminum nitride is an ideal material for thermal management and electrical applications because of its high thermal conductivity and electrical insulation. Aluminum nitride can be used to:
Radiator and radiator.
Electrical insulator of laser.
Chucks and clamps for semiconductor processing equipment.
Silicon wafer processing and processing.
Substrates and insulators for microelectronic and optoelectronic devices.
Electronic packaging substrate.
Chip carriers for sensors and detectors.
Laser thermal management module.
Molten metal fixture.
Microwave equipment packaging
