Ceramic High-Temperature Protection Ring Boron Nitride Sealing Vacuum Gasket Industrial Ceramic Part Cutting

                              Description                                             

High-Temperature Furnace Components

High-temperature furnaces (up to 2000°C) require components that can endure prolonged exposure to extreme heat
 without deformation or degradation—and hBN ceramics are engineered for this exact purpose. Hot-pressed at the
same extreme temperatures they’re designed to withstand (2000°C, 2000 psi), our hBN billets create dense, machinable
materials that excel as furnace linings, heating element supports, crucibles, and furnace fixtures.
Their exceptional thermal shock resistance and low thermal expansion ensure long service life,
reducing maintenance frequency and replacement costs. Whether you need standard or custom-shaped furnace components,
HBN ceramics deliver unmatched performance and durability for your high-temperature processing needs.

Boron Nitride Ceramic Insulating Parts

  • Excellent thermal shock resistance
  • High electrical resistivity – excluding aerosols, paints, and ZSBN
  • Low density
  • High thermal conductivity
  • Anisotropic (thermal conductance is different in different planes relative to pressing direction)
  • Corrosion resistant
  • Good chemical inertness
  • High temperature material
  • Non-wetting
  • High dielectric breakdown strength, >40 KV/mm
  • Low dielectric constant, k=4
  • Excellent machinability
