Aluminium nitride

TOYALNITE™

TOYALNITE™ is a high purity aluminium nitride (AlN) powder with excellent thermal conductivity and insulating properties.

For sintering, filler and beyond …

Characteristics

  • Very high purity AlN => Provides high thermal conductivity after sintering.

  • Particle size distribution adjustment => Reduces shrinkage of molded part and increases strength of sintered part.

  • Consistent quality management => Achieves stable quality.

Application examples

Electronic materials : substrate for power semiconductor device, substrate for LED, semiconductor manufacturing equipment, thermal conductive filler for TIM.
