Abstract
The solubility in the quaternary water–salt system Zr(SO4)2 · 4Н2О–Na2SO4–H2SO4–H2O at 25°C was studied. It was found that, in the system, there is crystallization of not only Na2SO4 and Zr(SO4)4 · 4H2O, but also sodium sulfate zirconates Na2Zr(SO4)2(OH)2 · 0.3H2O, Na4Zr(SO4)4 · 3H2O, and Na2Zr(SO4)2 · 3H2O and two new compounds, S1 and S2, which are presumably Na2ZrO(SO4)2 · 2H2O and Na2Zr2O2(SO4)3 · 6H2O.
