一、前言硅灰石矿物是一种自然产出的偏硅酸钙。它作为工业矿物仅有二十余年的历史。硅灰石的主要用途是作为陶瓷工业的配料,此外还在涂料工业、塑料与胶橡工业、磨料工业、电焊和绝缘产品等方面也得到应用。硅灰石的分子式为〔CaO·SiO_2〕_3,其理论组成是 CaO 48.3%、SiO_2 51.7%,组份中的钙可被少量的铁、锰及镁所置换。它是一种接触变质矿物,与其共生的常见矿物有石英、方解石,透辉石、石榴石、白云石。我省长崴子硅灰石矿经 X 光衍射和镜下观察,
First, the foreword Wollastonite mineral is a natural calcium metasilicate. It has only twenty years of history as an industrial mineral. Wollastonite is mainly used as a ceramic industry ingredients, in addition to the coatings industry, plastics and rubber and rubber industry, abrasive industry, welding and insulation products have also been applied. Wollastonite formula [CaO · SiO_2] _3, the theoretical composition of CaO 48.3%, 51.7% SiO 2, the composition of calcium can be a small amount of iron, manganese and magnesium replacement. It is a contact metamorphic minerals, symbiotic common minerals quartz, calcite, diopside, garnet, dolomite. Governor Wei Wei wollastonite mine by X-ray diffraction and microscopic observation,
