High-purity Boron Nitride Powder and Products
Boron Nitride Powder (hexa-boron nitride powder)
·
Characteristic :
Hexagonal boron nitride is a kind of white loose powder, similar to the nature of the graphite.
Subgroup of boron nitride powder, good electrical insulation, thermal conductivity and chemical corrosion resistance;
Oxidation temperature can reach 900 ℃,
When in the high temperature, also has good lubricity, is a kind of excellent high temperature solid lubricants;
Has a strong neutron absorption ability;
Chemical properties of stability, to almost all of the melt metals are shows chemical inertness, ability of high temperature to 2000 ℃.
Good performance of mechanical processing.
Hot-pressing boron nitride products
Hot-pressing boron nitride products by hexa-boron nitride powder high-temperature hot-pressing sintering and the mechanical processing into various shapes and specifications, mainly used for vacuum coating machine, power meter parts, rare earth metal smelting dry pot, heat conduction, heat resistant plate, etc
