Preparation method of superfine porous calcium silicate ceramic membrane

The invention discloses a preparation method of a superfine porous calcium silicate ceramic membrane. The preparation method comprises the following steps: by using CaCO3 and SiO2 as raw materials, synthesizing calcium silicate powder at 1270-1290 DEG C, carrying out double-roller crushing, and passing through a 325-mesh screen; and adding the screened calcium silicate powder into deionized water or glucose-dissolved deionized water, stirring and mixing, carrying out spray drying, carrying out compression molding in a mold, keeping the temperature to volatilize water, cooling, carrying out isostatic pressing in an isostatic pressing machine, and sintering to obtain the superfine porous calcium silicate ceramic membrane. The calcium silicate ceramic membrane has the characteristics of small pore size and uniform pore distribution, and has important application prospects in the fields of filtration, purification separation, chemical catalytic supports and the like. 本发明公开的超细多孔硅酸钙陶瓷膜的制备方法，步骤如下：先以CaCO和SiO为原料，在1270
