Description

INNOVACERA® Hot Press Boron Nitride Sheet Thickness 13 mm,  2 Square in stock (25 x 25 mm, 50 x 50 mm), custom size is available. White in color.

Hexagonal Boron Nitride has a microstructure similar to that of Graphite. In both materials, this structure made up of layers of tiny platelets is responsible for excellent machinability and low-friction properties. We called hexagonal boron nitride (HBN) or white graphite.

Features of Boron Nitride

  • High thermal conductivity
  • Low thermal expansion
  • Good thermal shock resistance
  • High electrical resistance
  • Low dielectric constant and loss tangent
  • Microwave transparency
  • Non-toxic
  • Easily machined — non-abrasive and lubricious
  • Chemically inert
  • Not wet by most molten metals
