    HBN Boron Nitride Ceramic Tube

    Boron nitride tubes made of hot pressed boron nitride ceramics have good electrical insulation, the breakdown voltage is about 3-4 times of alumina ceramic. Therefore, boron nitride tubes could be used as good insulators. By the way, boron nitride tubes also have high temperature resistance and good thermal shock resistance, they can work up to 2100 ℃ under atmosphere protection and 1900 ℃ under vaccum, cracks will not happen even when big temperature changes happen. Boron nitride tubes have low hardness and cannot be used in wear resistance jobs or applications with strong force impact. Any inquiry please email or call +86 13860446139
