The phase diagrams of Na_2CrO_4- (NH_4)_2CrO_4-H_2O system at 20℃ and 50℃ have been determined by solubility method. The experimental results have also been verified by mathematical method. The phase diagrams show that there is a double salt of NaNH_4Cro_4• 2H_2O formed in the system, which will decrease the purity of (NH_4)_2CrO_4 Consequently, a method is found to separate the fixture of ammonium chromate and double salt by analysing the phase diagrams.
