Abstract

PURPOSE: To produce fibrous or mica-form calcium sodium silicate in a high yield by charging an SiO2-contg. cpd., Na2CO3 and a water sol. Ca cpd. in a specified ratio followed by hydrothermal reaction under press.
CONSTITUTION: An SiO2contg. cpd., Na2CO3 and a water col. Ca cpd. are charged as follows: considering Na2O in the raw materials to be Xmol, SiO2 to be Ymol, CaO to be Zmol and H2O to be Smol, the ratio of Y/Z is adjusted to 3.0W4.0, and alkalinity coefficient U to 0.002W0.01. The coefficient is calculated according to equations I and II in case Na salt other than Na hydrogencarbonate is by-produced or is not by-produced by reaction, respectively. The charged raw materials are then reacted in an aq. medium under press. at 150W250°C to obtain fibrous or mica- form calcium sodium silicate. This salt is used as an ion exchanger or a desiccating agent.
