氮化硼陶瓷真空下長(zhǎng)期使用溫度1800度,**使用溫度1900度;氣氛保護(hù)下長(zhǎng)期使用溫度2000度,**使用溫度2100度。高溫絕緣,電絕緣性能隨著溫度升高而變強(qiáng),抗急冷急熱。空氣中使用超過(guò)900度會(huì)氧化。
The the max. service temperature BN ceramics: 1800 ℃~1900 ℃ in vacuum,2000 ℃~2100℃ in inert. BN ceramic is high-temperature insulation, electrical insulation with the temperature rise and become strong, resistant to sudden cold and hot. It will be oxidizing in over 900 ℃.
