黑碳化硅的分類碳化硅(SiC)是用石英砂、石油焦(或煤焦)、木屑為原料通過電阻爐高溫冶煉而成。碳化硅在大自然也存在罕見的礦物，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)濟的一種。可以稱為金鋼砂或耐火砂。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。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。另一種是黑碳化硅，有金屬光澤，含SiC95%以上，強度比綠碳化硅大，但硬度較低，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，機械強度高于剛玉，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。

style="text-indent:25px">如果與水、氫、氮、硫、鹵素等氣體及熔融的鋁、堿、鹽、熔融金屬、金屬氧化物接觸的話，也會發(fā)生反應(yīng)、腐蝕或氧化現(xiàn)象。硅碳棒在連續(xù)式窯爐與間歇式窯爐中，前者的壽命較長。硅碳棒在使用中表面氧化生成二氧化硅薄膜，長時間使用使二氧化硅皮膜增加，硅碳棒阻值也隨之增加。二氧化硅薄膜在結(jié)晶臨界點（270℃）附近發(fā)生異常膨脹、收縮。因在間歇式窯爐中間斷使用總在此溫度上下浮動，所以反復(fù)破二氧化硅薄膜，加速氧化。因此停電爐溫降至室溫時經(jīng)常急劇增加電阻。如果硅碳棒保護管阻值不同，串聯(lián)時電阻高的硅碳棒負荷較集中，易導(dǎo)致某一根硅碳棒的電阻快速增加，壽命變短。硅碳棒一般是串、并聯(lián)接線結(jié)合使用。建議采用2根串聯(lián)為一組后多組并聯(lián)。特別當(dāng)爐內(nèi)溫度超過1350℃時必須并聯(lián)。三相接線時建議使用開放三角形接線。奧翔硅碳擁有先進的產(chǎn)品生產(chǎn)設(shè)備，雄厚的技術(shù)力量。安徽電廠氮化硅保護管出口</p><p
