摘要：

The solubility in the quaternary water-salt system Zr(SO4)(2) center dot 4De(2)D-Na2SO4-H2SO4-H2O at 25A degrees C was studied. It was found that, in the system, there is crystallization of not only Na2SO4 and Zr(SO4)(4) center dot 4H(2)O, but also sodium sulfate zirconates Na2Zr(SO4)(2)(OH)(2) center dot 0.3H(2)O, Na4Zr(SO4)(4) center dot 3H(2)O, and Na2Zr(SO4)(2) center dot 3H(2)O and two new compounds, S-1 and S-2, which are presumably Na2ZrO(SO4)(2) center dot 2H(2)O and Na2Zr2O2(SO4)(3) center dot 6H(2)O.
