Process for the preparation of crystalline sodium disilicates
In order to prepare crystalline sodium disilicates having a sheet structure, a molar ratio of SiO2 to Na2O of (from 1.9 to 2.1):1 and a water content of less than 0.3% by weight, a water glass solution is first obtained by reacting sand with aqueous sodium hydroxide in a molar ratio SiO2 to Na2O of...
