天然硅灰石是一种节能型矿物原料,能降低烧成温度,加快烧成周期。但由于天然硅灰石资源短缺,在釉面砖生产中的应用数量十分有限。俄罗期某研究院利用磷石膏废料、硅砂和其他原料,在1200℃下合成人造硅灰石,用于二次快烧釉面砖获得成功。经矿物鉴定分析,烧成的釉面砖主要锆相晶是α-硅灰石、长石和钙镁橄榄石。试验中用30％～50％合成硅 Natural wollastonite is an energy-saving mineral raw materials, can reduce the firing temperature and speed up the firing cycle. However, due to the shortage of natural wollastonite resources, the application of glazed tile production is very limited. An institute in Russia made use of phosphogypsum scrap, silica sand and other raw materials to synthesize artificial wollastonite at 1200 ° C for the success of the second flash fired glazed tile. The mineral identification analysis, the main glazed zirconia crystal phase is a-wollastonite, feldspar and calcium and forsterite. Test with 30% to 50% synthetic silicon
