点击图片查看原图电熔莫来石是一种人工合成的电熔制品，结晶体为针状，它具有热震稳定性好，抗折强度大，荷重软化温度高，硬度大，高温蠕变小等特点。
电熔莫来石广泛应用于低蠕变热风炉转，铁水包及鱼雷罐砖，高温工业窑炉砖，玻璃窑衬砖及高温匣钵、棚板等耐火制品。
Fused Mullite is a kind of artificially producedfusedproduct with acicular crystals, which has good thermalresistance,strong modulus of rupture, high refractoriness underload (RUL),high hardness, and good high-temperaturecreep-resistance.
Fused Mullite iswidely used in manufacturing manyrefractory products, like the lowcreep-rupture bricks for thehot-air stove, melting-iron groove ortorpedo car, high-temperatureindustrial kiln, glass meltingfurnace, as well as in producinghigh-temperature saggers or shedplanks, etc.
