INNOVACERA® Hot Press Boron Nitride Rod Diameter 20 mm, 3 length in stock (1 mm, 25 mm, 100 mm), custom length 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
