Boron Nitride Powder (hBN) is also known as 'White Graphite', has similar (hexagonal) crystal structure as of Graphite. This crystal structure provides excellent lubricating properties. HBN is much superior to Graphite and has following characteristics:
Excellent Lubricating Properties due to low Coefficient of Friction at 0.15 to 0.70
Good Chemical Inertness
Electrical Insulator
Thermal Conductor (result: Better heat dissipation)
High Temperature Stability, 1000º C in Air, 1400º C in Vacuum and 1800º C in Inert gas
Low Thermal Expansion
Low Dielectric Constant
High Load bearing properties
Non-Wetting: HBN is not wetted by Glasses, Salts and (most) metals, therefore it provides strong resistance to chemical attack Easy Machineability (in hot pressed state). Complex shapes can be machined from hot pressed structure.
