ABSTRACT OF THE DISCLOSURE There is disclosed a particulate sodium zirconium car- bonate hydrate compound having an ionic composition corresponding to analysis, exclusive of water of hydration, as follows:- (Na)A (Zr)B (CO3)C wherein, when B, measured as ZrO2, is assigned the value 1, A has a value of from about 0.8 to about 1.2 and C, measured as CO2, has a value of from about 0.8 to about 1.2. The method of pre- paration of this compound is as follows: 1) preparing a metastable solution comprising zirconium, sodium, sulfate and carbonate ions and having a pH of from about 8 to a- bout 11.5, the molar ratios of said sodium. sulfate and carbon- ate ions to each zirconium ion being within the ranges of from about 6 to about 10, from about 2 to about 3 and from about 2 to about 4 respectively and the concentration of said zirconium ions in said solution being from about 0.3 molar to about 009 molar, 2) heating said metastable solution to greater than about 90°C; and, 3) holding said solution at greater than about 90°C for sufficient time to allow formation of said product. The compound exhibits a substantially uniform particle size which makes it suitable for the preparation of zirconium phosphate.
