碳化硅是一種理想的密封材料，具有優(yōu)良的耐化學腐蝕性能，較高的機械強度，耐高溫，耐磨性好，自潤滑性好，組對 性能好，摩擦系數小，優(yōu)異的熱傳導性等特點。特別是常壓燒結碳化硅，能夠滿足更為苛刻的工況條件。

碳化硅作為高溫結構材料，已廣泛地應用于石油，化工，機械，軍工，船舶，航天，汽車等領域。并可廣泛地用作機械 密封的摩擦副付材料，尤其是泥漿泵用的摩擦付材料。

Silicon carbide is the idea sealing material.lt has good corrosion resistance,higher mechanical intensity, excellent resisting wearability and high temperature, good self-lubricity and making-group, low friction factor , good heat-conduction and so on. Especially self sintered silicon carbide, it can suit for the hard working condition.

The silicon carbide ,as the high- temperature structural material, is widely used in the petroleum, the chemical industry, Machinery ,war industry, shiping, spaceflight, the automobile and other fields.Also, it is widely applied to friction material of mechanical seals, especially friction material of slush pump.
