Product Description High Temperature Material Hexagonal Boron Nitride Ceramic Tube Pipe BushProduct Description Boron Nitride Ceramics:Boron nitride crystal belongs to the hexagonal crystal system, its structure is similar to that of graphite, and its performance has many similarities, so it is also called "white graphite". 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:Boron nitride ceramic has good heat resistance, thermal stability, thermal conductivity and high temperature dielectric strength. It 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. 1) BN is the only machinable ceramic with a processing precision of 0.01mm; 2) Insulation strength 2300v / cm, 8 times Al2O3; RT resistance > 10Ω.cm at 1000 ° C; 3) Its melting point is as high as 2800 ° C, it is a typical electrical insulator, and also an excellent thermal conductor; 4) Excellent thermal shock resistance, returning 100 times from 20 ° C to 1000 ° C without damage; 5) General metals (iron, copper, aluminum, lead, etc.), rare earth metals, precious metals, semiconductor materials (silicon, potassium arsenide), glass, molten salt (crystal, fluoride, slag), inorganic acids, alkalis Does not react.Boron nitride has excellent insulation properties, high thermal conductivity, chemical stability and machinabilityAs a semiconductor processing member, an electric furnace member, an electronic component assembly jig, etc. Application:Boron nitride ceramics 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.
