Dispersion composition of basic zirconium sulfate precipitates
The goal of this work was to investigate in detail the dispersion degree of basic zirconium sulfate precipitates obtained from zirconium nitrate and chloride solutions at different temperatures. The precipitate of basic zirconium sulfate obtained from chloride solutions and containing 0.55 +/- 0.05 mole SO/sub 4//sup 2 -/ per mole Zr consists of aggregated particles whose size increases from 15-20 to 5-10 ..mu..m when the precipitation temperature is raised in the range of 60-100/sup 0/C. The size of primary particles, which comprise the aggregate, is about 1 ..mu..m. From nitrate solutions, basic zirconium sulfate precipitates below 85-90/sup 0/C in the form of the same aggregates as in the case of chloride solutions, and above this temperature, in the form of nonaggregated particles measuring 1-1.5 ..mu.. m. The same characteristics, regardless of the starting solution, are exhibited by basic zirconium precipitates containing less than 0.5 mole SO/sub 4//sup 2 -/ per mole Zr.
