PREPARATION METHOD OF ANHYDROUS CALCIUM SILICATE AND ANHYDROUS CALCIUM ALUMINA SILICATE USING CALCIUM OXIDE OR CALCIUM HYDROXIDE, BY HEATING AT HIGH TEMPERATURE

摘要

Purpose: providing the above method and prepare anhydrous calcium silicates and anhydrous calcium aluminium hydrosilicate, obtains the porous material with good high temperature resistant, insulation and voice testing by recycling waste. Construction: anhydrous calcium silicates (CaO-nSiO2) forms mixture preparation by mixing CaO, Ca (OH) 2 and SiO2; In 700-1.050C.At a temperature of the heating anhydrous calcium aluminium hydrosilicate (CaO-mAl2O3-nSiO2) of mold body by mixing CaO, Ca (OH) 2, aluminium oxide, Al (OH) 3 and SiO2, form mixture preparation; In 800-1,350C.At a temperature of heat mold body
