黑碳化硅 Black silicon carbide
黑碳化硅是以石英砂，石油焦和優質硅石為主要原料，通過電阻爐高溫冶煉而成。其硬度介于剛玉和金剛石之間，機械強度高于剛玉，性脆而鋒利。
黑色碳化硅是用石英砂和石油焦的混合物在高溫電阻式爐中生產的。
黑色碳化硅的硬度大于熔融氧化鋁，但小于合成金剛石。
其機械強度大于熔融氧化鋁，但易碎且鋒利。這種礦物具有一定的導電性和導熱性。
Black Silicon Carbide is produced in a high temperature electric
resistance-type furnace from a mixture of quartz sand and petroleum coke.
The hardness of black silicon carbide is greater than fused alumina but less
than synthetic diamond.
Its mechanical intensity is greater than fused alumina, but is brittle and very
sharp. The mineral has some electrical and heat conductivity.
