黒炭化ケイ素は石英砂でできています, 石油コークスとシリカを主原料, 抵抗炉高温製錬を通して. その硬度はコランダムとダイヤモンドの間です, 機械的強度はコランダムより高い, もろくて鋭い.
What are the properties of black silicon carbide provided by black silicon carbide manufacturers? Let’s learn more about it with Henan Superior Abrasive.
黒色炭化ケイ素の利点
ブラックシリコンカーバイド, with metallic luster, contains more than 95% SiC, with greater strength than green silicon carbide, but lower hardness, mainly used for grinding cast iron and non-metallic materials.
Molecular formula is SiC, its hardness is between corundum and diamond, 機械的強度はコランダムより高い, can be used as abrasives and certain other industrial materials. Industrial silicon carbide was successfully developed in 1891 and is an early man-made abrasive. Although a small amount of silicon carbide exists in meteorites and the earth’s crust, no mining source has been found to date.
黒色炭化ケイ素は約 98.5% SiC, its toughness is higher than that of green silicon carbide, and is mostly used for processing materials with low tensile strength, ガラスなど, セラミック, 結石, 耐火材料, 鋳鉄および非鉄金属.
Silicon carbide advantages
Due to its stable chemical properties, 高い熱伝導率, 熱膨張係数が低く、耐摩耗性に優れています, 炭化ケイ素 is used as an abrasive, but also has many other uses, 例えば: 水力タービンの羽根車やシリンダー本体の内壁にコーティングされた炭化ケイ素粉末への特殊なプロセス, which can improve its wear resistance and extend the service life of 1 に 2 回; 耐火物を作るのに使われる, ヒートショック, 小さいサイズ, 軽量で高強度, 良い省エネ効果. 低品位炭化ケイ素 (約を含む 85% SiC) is a better deoxidizer, 製鉄のスピードを加速できる, 化学組成の制御を容易にする, 鋼の品質を向上させる. 加えて, silicon carbide is also used in large quantities to make electric heating elements silicon carbon rods.
Silicon carbide is very hard, has excellent thermal conductivity, is a semiconductor, and can resist oxidation at high temperatures.
