Hot-Press Boron Nitride BN Insulation Tubes, Sleeve, And Parts For Vacuum Furnace
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.
The main products of Boron Nitride Ceramics
Hot pressing hexagonal boron nirtride ceramic and boron nitride composite ceramic, includes:
