PROBLEM TO BE SOLVED: To provide a method for producing vanadium phosphate compounds, i.e., vanadyl hydrogenphosphate hemihydrate(VOHPO4.1/2H2O), vanadyl hydrogenphosphate monohydrate(β-VOHPO4.H2O) and trisvanadyl diphosphate pentahydrate((VO)3(PO4)2.5H2O). SOLUTION: This method for producing the above vanadium phosphate compounds comprises treating the corresponding vanadium compounds with formic acid, water and phosphorus compound(s).
