碳化硅简介
碳化硅（SiC）是用石英砂、石油焦（或煤焦）、木屑为原料通过电阻炉高温冶炼而成。碳化硅在大自然也存在罕见的矿物，莫桑石。碳化硅又称碳硅石。在当代C、N、B等非氧化物高技术耐火原料中，碳化硅为应用最广泛、最经济的一种。可以称为金钢砂或耐火砂。碳化硅是用石英砂、石油焦（或煤焦）、木屑（生产绿色碳化硅时需要加食盐）等原料在电阻炉内经高温冶炼而成。目前我国工业生产的碳化硅分为黑色碳化硅和绿色碳化硅两种，均为六方晶体，比重为3.20～3.25，显微硬度为2840～3320kg/mm2
Introduction of silicon carbide
Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting. There is also a rare mineral silicon carbide in nature, and the mo SangShi. Silicon carbide is also called the moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic. Can be called corundum sand or refractory. Silicon carbide is using quartz sand and petroleum coke or coal tar, wood chips (green silicon carbide production need to add salt) such as raw materials in the Canon of high-temperature resistance furnace smelting. At present, the industrial production of silicon carbide can be divided into two black silicon carbide and green silicon carbide, are the six-party crystal, specific gravity of 3.20 ~ 3.25, the microhardness of 2840 ~ 3320 kg/was

碳化硅用途
(1)作为磨料，可用来做磨具，如砂轮、油石、磨头、砂瓦类等。
(2)作为冶金脱氧剂和耐高温材料。
碳化硅主要有四大应用领域,即:功能陶瓷、高级耐火材料、磨料及冶金原料。目前碳化硅粗料已能大量供应,不能算高新技术产品,而技术含量极高的纳米级碳化硅粉体的应用短时间不可能形成规模经济。
(3)高纯度的单晶，可用于制造半导体、制造碳化硅纤维。
黑碳化硅称为黑碳化硅粒度砂，黑碳化硅分黑碳化硅粒度砂和黑碳化硅微粉两大类产品.
黑碳化硅粒度砂是用碳化硅自然块经过粉碎,研磨,酸碱洗,水洗,烘干,筛分等工艺,原料：石英砂(Sio2)和无烟煤或石油焦(c)，在摄氏1800度以上高温条件下生成的非金属矿产品,它具有硬度高,膨胀系数小,性脆,导热性好等特点,广泛应用于磨料磨具,电子产品研磨,耐火材料,特种陶瓷,泡沫陶瓷,涂料塑料添加改性,汽车配件,军工航空,炼钢用脱氧剂等。
