Heating furnaces - Import export

Boron nitride can be long-term used at 1800 degrees under vacuum atmosphere. With gas protection, Boron Nitride can be used at 2100°. Boron Nitride is with high thermal shock resistance, no cracks under extreme cold & high temperature. If you take out Boron Nitride from 1000 degree furnace and colding it within short minutes. It still won't break even repeat this test with 100 times. > Matching materials: BN-99, BN-AL > Advantages: high temperature resistance (2000℃), thermal shock resistance, high electrical breakdown strength (3 -4 times that of alumina), carbon atmosphere corrosion resistance is much stronger than alumina > Used for polysilicon ingot furnace, graphitization heat treatment furnace, vacuum sintering furnace, atmosphere furnace ect. Grades 5 grades of boron nitrides are involved in Boron Nitride product series. * BN99 ● CABN ● ALBN ● ZRBN ● ZABN ● SB
