【碳化硅產(chǎn)品介紹】:
 
     碳化硅俗稱金剛砂（SiC）或耐火砂、碳硅石，主要分為黑色碳化硅和綠色碳化硅，是用石英砂、石油焦（或煤焦）、木屑為原料（生產(chǎn)綠色碳化硅時需要加食鹽）通過電阻爐高溫冶煉而成，均為六方晶體。
 
【碳化硅的分類】:
 
      碳化硅主要分為以下兩種：
    （1）黑碳化硅含SiC約95%，其韌性**綠碳化硅，大多用于加工抗張強(qiáng)度低的材料，如玻璃、陶瓷、石材、耐火材料、鑄鐵和有色金屬等。
    （2）綠碳化硅含SiC約97%以上，自銳性好，大多用于加工硬質(zhì)合金、鈦合金和光學(xué)玻璃，也用于珩磨汽缸套和精磨高速鋼刀具。
