莫来石的主要成分是氧化铝和二氧化硅，统称为铝硅酸盐矿物。它是由铝硅酸盐在高温条件下形成的一种矿物。当铝硅酸盐被人工加热时，也会形成莫来石。石头。近年来，我国煤炭资源的清洁利用不断提高。电厂生产的粉煤灰中也含有莫来石相。其中准格尔电厂粉煤灰中莫来石含量约为40%。莫来石的化学成分为3Al2O3·2SiO2-2Al2O3·SiO2。从相图上看，莫来石是二元相图体系中唯一稳定的结晶铝硅酸盐。其晶体结构由硅氧四面体和铝氧四面体沿C轴随机排列形成双股。 The double strands are connected by aluminoxy octahedra. In its structure, the aluminoxy octahedron plays a role in the entire structure. The support of the skeleton and the two ordering methods of incommensurate amplitude modulation make it have stable energy, so mullite has very good chemical stability. At the same time, it has good properties such as high refractoriness, strong electrical insulation, chemical corrosion resistance, good shock resistance, high load softening temperature, and creep resistance. It is now widely used in metallurgy, chemical industry, petroleum, electric power, national defense, etc. Many industrial fields.
