Product Description

Features & Benefits

  • High thermal conductivity: 4-5 times higher than alumina
  • High electrical insulation: excellent dielectric properties
  • High strength and hardness: comparable to sapphire
  • Low coefficient of thermal expansion: close to that of silicon
  • Good thermal shock resistance: able to withstand rapid temperature changes

Markets & Applications

  • Electronic and semiconductor industries: as substrates for power modules, IC packages, and LED lighting
  • Aerospace and defense: as thermal management components for high-power electronics
  • Medical devices: as implantable electronic components due to biocompatibility and low electrical impedance
  • High-temperature processing industries: as crucibles and thermocouple protection tubes in furnaces and kilns.
