FIELD: silicate materials production.

SUBSTANCE: invention relates to the production of silicate materials, in particular synthetic zeolite, and can be used for the production of sorbents and catalysts. The method for producing synthetic aluminosilicate zeolite includes hydrothermal treatment of the initial mixture, which contains a source of aluminum oxide, a source of sodium oxide, liquid sodium glass, calcium oxide (lime). As a source of aluminum oxide and as a source of sodium oxide, the initial mixture contains a recycled solution of alumina production. In this case, the initial mixture has the following ratio of components, wt.%: recycled solution of alumina production 94-95.2; liquid sodium glass 1.6-2.2; calcium oxide 3.2-3.8.

EFFECT: development of a method for producing synthetic aluminosilicate zeolite, which makes it possible to simplify the production process and significantly reduce its duration.
