Thermalox CR Beryllia ceramic components convey an exceptional combination of properties:

  • Second only to Diamond among electrical insulating materials, Thermalox CR material is an exceptionally high purity crucible material with excellent etch resistance.
  • Low Dielectric Constant (6.76) and low tan╬┤ dielectric loss tangent (.0004 at 1 MHz), permitting improved circuit performance at high frequencies.
  • A Coefficient of Thermal Expansion (CTE) of 9.0 intermediate to silicon or gallium arsenide and metals.
  • Ten times greater thermal conductivity than alumina ceramics.
