Hot Pressed Boron Nitride

Boron nitride can be hot pressed to form complex shapes, as well as used as an additive in other materials like alloys, plastics, and even cosmetics.

Hot pressed boron nitride shapes are used as critical components in applications where excellent thermal shock resistance, high electrical resistivity and chemical and corrosion resistance is required.

  • High temperature insulators
  • Thermocouple tubes
  • Molten metal crucibles and nozzles
  • High temperature furnace components
  • Rollers and formers for the glass industry
