黑碳化硅的分類(lèi)碳化硅(SiC)是用石英砂、石油焦(或煤焦)、木屑為原料通過(guò)電阻爐高溫冶煉而成。碳化硅在大自然也存在罕見(jiàn)的礦物，莫桑石。碳化硅又稱碳硅石。在當(dāng)代C、N、B等非氧化物高技術(shù)耐火原料中，碳化硅為應(yīng)用**普遍、**經(jīng)濟(jì)的一種。可以稱為金鋼砂或耐火砂，上海鋼廠氮化硅保護(hù)管批發(fā)。碳化硅是用石英砂、石油焦(或煤焦)、木屑(生產(chǎn)綠色碳化硅時(shí)需要加食鹽)等原料在電阻爐內(nèi)經(jīng)高溫冶煉而成。目前我國(guó)工業(yè)生產(chǎn)的碳化硅分為黑色碳化硅和綠色碳化硅兩種，均為六方晶體，比重為～，顯微硬度為2840～3320kg/mm2。包括黑碳化硅和綠碳化硅，其中：綠碳化硅是以石油焦和質(zhì)量硅石為主要原料,添加食鹽作為添加劑，通過(guò)電阻爐高溫冶煉而成。其硬度介于剛玉和金剛石之間,機(jī)械強(qiáng)度高于剛玉。常用的碳化硅磨料有兩種不同的晶體，一種是綠碳化硅，含SiC97%以上，主要用于磨硬質(zhì)含金工具，上海鋼廠氮化硅保護(hù)管批發(fā)。另一種是黑碳化硅，有金屬光澤，含SiC95%以上，強(qiáng)度比綠碳化硅大，但硬度較低，上海鋼廠氮化硅保護(hù)管批發(fā)，主要用于磨鑄鐵和非金屬材料。分子式為SiC，其硬度介于剛玉和金剛石之間，機(jī)械強(qiáng)度高于剛玉，可作為磨料和其他某些工業(yè)材料使用。工業(yè)用碳化硅于1891年研制成功，是**早的人造磨料。在隕石和地殼中雖有少量碳化硅存在。奧翔硅碳愿和各界朋友真誠(chéng)合作一同開(kāi)拓。上海鋼廠氮化硅保護(hù)管批發(fā)</p><div
