莫來石簡介
?
? ? 莫來石是一種耐火原料，這一類礦物比較稀少。莫來石是鋁硅酸鹽在高溫下生成的礦物，人工加熱鋁硅酸鹽時會形成莫來石。天然的莫來石晶體為細長的針狀且呈放射簇狀。莫來石礦被用來生產高溫耐火材料。在C/C復合材料中多作為熱障涂層，應用廣泛。
?
? ? 莫來石AI203-SI02元系中常壓下穩定的二元固溶體，化學式為3AI203-2SI02天然的莫來石非常少，通常燒結法或電容法等人工合成。化學式A1xSi2-xO5.5-0.5x密度;3.16g/cm3莫式硬度；6-7耐火度：1800C是穩定1810C分解為剛玉和液相。

莫來石用途
?
? ? 莫來石在工業上運用的是比較多的，它可以制作成高純電熔莫來石，普通電熔莫來石，和輕燒莫來石等，它有磚塊狀和粉末狀的類別。高純電熔莫來石采用高純度石英砂，工業氧化鋁，在超大電弧爐上熔煉而成，電熔莫來石是一種人工合成的電熔耐火產品。
?
? ? 莫來石主要用于熔膜鑄造、石膏填料V法造型與真空吸鑄的造型材料，及大、中、小型鑄鋼、鑄銅件、爐襯材料，還用于制造水玻璃、耐火制品、混凝土材料等，廣泛用于機械、航空、兵器、冶金、石油、保溫、燒結、建筑等行業。

Introduction of mulliteMullite is a kind of excellent refractory raw material, this kind of mineral is scarce.Mullite is aluminum silicate at high temperatures generated minerals, artificial heating will form mullite aluminum silicate.Natural mullite crystals as elongated needle and radiation clumps.Mullite ore is used to produce high temperature refractory materials.In C/C composites as a thermal barrier coating, more widely used.Mullite AI203 - SI02 is stable under normal pressure in the binary solid solution, the chemical formula for 3 AI203-2 SI02 natural mullite were very small, usually sintering, such as synthetic or capacitance method.Chemical formula A1xSi2 xO5.5-0.5 x density;3.16 g/cm3 mo type hardness;6-7: refractoriness is 1800 c 1810 c is decomposed into corundum and liquid phase.Mullite purposesMullite in industry use is more, it can be made into high purity fused mullite, fused mullite, and light burning mullite, etc, it has brick block and the category of the powder.High purity fused mullite using high purity quartz sand, alumina industry, on the large electric arc furnace smelting, fused mullite is a kind of synthetic fused refractory products.Mullite is mainly used for melting membrane casting, plaster packing V method of modelling and vacuum suction casting molding materials, and large, medium and small cast steel, cast copper pieces, lining material, also used in the manufacture of sodium silicate, refractory products, concrete materials, widely used in machinery, aviation, weapons, metallurgy, oil, heat preservation, sintering, construction and other industries.
