前言硅灰石是一种自然产出的偏硅酸钙CaSiO_3,它作为工业矿物,应用的历史很短。直到1950年,硅灰石还未以任何数量进入市场。从六十年代起,它作为一种低温快速烧成釉面砖的理想原料,在釉面砖生产上获得广泛的应用。此外,硅灰石还用于涂料、油漆、塑料和橡胶等工业部门。世界市场硅灰石的来源主要是美国。目前,美国年产约10万吨。其中80%用于本国,其
Wollastonite is a naturally occurring calcium metasilicate, CaSiO 3, which has a short history of application as an industrial mineral. Wollastonite did not enter the market in any amount until 1950. Since the 1960s, it has been widely used in the production of glazed tiles as an ideal raw material for the rapid firing of glazed tiles at low temperatures. In addition, wollastonite is also used in coatings, paints, plastics and rubber and other industrial sectors. The source of wollastonite in the world market is mainly the United States. At present, the United States has an annual output of about 100,000 tons. 80% of them are used domestically
