黑碳化硅 Black silicon carbide
黑碳化硅是以石英砂，石油焦和优质硅石为主要原料，通过电阻炉高温冶炼而成。其硬度介于刚玉和金刚石之间，机械强度高于刚玉，性脆而锋利。
黑色碳化硅是用石英砂和石油焦的混合物在高温电阻式炉中生产的。
黑色碳化硅的硬度大于熔融氧化铝，但小于合成金刚石。
其机械强度大于熔融氧化铝，但易碎且锋利。这种矿物具有一定的导电性和导热性。
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.
