AlN ceramic aluminum nitride part Casting Forming

Product Description
With its properties of electrical insulation and excellent thermal conductivity, Aluminum Nitride Ceramics is ideal for
applications where heat dissipation is required. In addition, since it offers a coefficient of thermal expansion (CTE) near that of silicon, and excellent plasma resistance, it is used for semiconductor processing equipment components.
Advantages:
· High thermal conductivity combined with good electrical insulation characteristics.
· Exceptional stability when exposed to many molten salts.
· Thermal stability up to at least 1500°C
· Favorable mechanical characteristics extending into the high temperature range.
· Low thermal expansion and resistance to thermal shock.
· Special optical and acoustic characteristics.

Physical Properties
· Flexural strength is 300 ± 5MPa
· Coefficient of thermal expansion is 5.6×10-6K-1 (20-1000°C)
