Aluminum Nitride Tube Properties 

High thermal conductivity,(170-230W/mK), up to 9.5 times than that of Alumina
Similar coefficient of thermal expansion to that of silicon(Si)
Higher electric insulation, and Smaller dielectric constant
Higher mechanical strength (450MPa)
Superior corrosion resistance against molten metal
Very high purity, no toxicity

Aluminum Nitride Tube is stable in inert atmospheres at temperatures over 2000°C. It exhibits high thermal conductivity but is, uniquely, a strong dielectric. This unusual combination of properties makes AlN a critical advanced material for many future applications in optics,lighting, electronics and renewable energy.
