Definitions

  • U.S. Pat. No. 3,435,398 discloses the doping of cubic boron nitride with beryllium, sulfur, selenium, boron, silicon, germanium, etc., and the use of a single crystal thereof in a thermistor device.
  • Both boron nitride abrasive, hereinafter referred to as CBN, and diamond must be formed under conditions of very high temperature and pressure.
  • Silicon carbide on the other hand, can be formed at atmospheric pressure under high temperature conditions. Thus, in order to add dopant to silicon carbide it is only necessary to have the dopant material, which may be a boron compound, present in the melt.
