Data on the analysis of crystalline products of the subsidence of sodium hydrosilicate solutions with the solutions of salts of various metals are presented. Features of the chemical composition of subsidence crystalline products are shown: when using the salts of alkali-earth metals, the formation of a metal carbonate is observed that’s why in the course of the synthesis of hydrosilicates of alkali metals, it is reasonable to avoid the intensive agitation of the mix and air-entrainment ; when using amphoteric metals, the carbonization is not observed and the chemical composition of products is determined by the type of the metal used. The pH value of the synthesis medium when using amphoteric metals don’t influence on the degree of crystalliness of hydrosilicates obtained, but crystalline products with different content of combination water are formed. Conducting the synthesis at acid values of pH makes it possible to obtain a large amount of the product and synthesize the substance not containing sodium.
