China Supplier Hexagonal Boron Nitride/Cubic Boron Nitride with CAS 10043-11-5
Hexagonal Boron Nitride 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 0.7.
-Good Chemical inertness.
-Electrical Insulator
-Thermal Conductor (result:better heat dissipation).
-High Temperature Stability,1000C in Air,1400C in Vacuum and 1800C 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.
