The invention relates to a method for producing double phosphates, in particular a double titanium phosphate and magnesium hydrate, and allows to increase the yield of the product and simplify its preparation. To obtain titanium double phosphate hydrate and magnesium, titanium and magnesium-containing compounds, which use titanium and ammonium sulfate and magnesium acetate, are treated with orthophosphoric acid at an initial molar ratio of: iTi -: POH-, equal to (10-15) 1: (13-20). Next, the product is filtered, washed and dried. As a result, the product yield is increased to 100%, the process of its preparation is simplified. 1 tab. ate about 00 ate ate |
