Reputation depends on quality, quality comes from Hard!
Boron Nitride Ceramic:
The boron nitride usually produced is a graphite type structure, commonly known as white graphite. The other is a diamond type, which is similar to the principle that graphite is converted into diamond. Graphite-type boron nitride can be converted into diamond-type boron nitride at high temperature (1800 ° C) and high pressure (800 MPa). The boron nitride has a B-N bond length (156 pm) similar to that of diamond at C-C bond length (154 pm), and its density is similar to that of diamond. Its hardness is comparable to that of diamond, and heat resistance is better than diamond. It is a new high temperature resistant superhard material for making drills, abrasive tools and cutting tools. Boron nitride is a crystal composed of a nitrogen atom and a boron atom. The chemical composition is 43.6% boron and 56.4% nitrogen with four different variants: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) and wurtzite nitrogen. Boron (WBN).
properties:
It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dissipating material and high temperature insulating material. Boron nitride has good chemical stability and is resistant to most of the molten metal. It also has good self-lubricating properties. Boron nitride products have low hardness and can be machined with an accuracy of 1/100 mm.
Application industry:
Boron nitride can be used in the manufacture of high-temperature containers for metallurgical melting, semiconductor heat-dissipating insulation parts, high-temperature bearings, thermowells, and glass forming dies.
