Aluminium Nitride powder for sintering; TOYALNITE®
Outline
TOYALNITE® is an aluminium nitride powder that has high thermal-conductivity with insulating properties.
Features
| High thermal-conductivity | High purity makes high thermal-conductivity after sintering. |
|---|---|
| High bending strength | High strength of sintered body is gained by broad particle size distribution. |
| Insulation/Thermal expansion | High insulation-properties. Coefficient of thermal-expansion close to Si-chip. |
