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.

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.


Most of our products are customized according to customers' drawing or designs,please send you drawings or designs to us,we will check it and send quotation to you.
