FIELD: production of synthetic zeolites, types A not containing binder. SUBSTANCE: natural aluminosilicate is mixed with commercial carbon in the amount of 2 to 8%. Then mixture is treated with 3-% solution of sodium chloride till plastic mass is obtained, after which it is granulated. Granules are subjected to heat treatment and then to cooling followed by hydrothermal crystallization, washing with solution of orthophosphoric acid at pH of 4 to 5 and drying. EFFECT: enhanced strength of zeolite as compared with zeolites produced by known methods. 1 tbl, 6 ex
