Precipitation and complex solubility of zirconium

neutral zirconium sulfate Zr(S04) 2 as the slope of the solubility line over this range is - 2. This is easily disproved as it is known that the neutral zirconium sulfate is an extremely soluble salt (3, 18, 19). The reported solubility exceeds by several orders of magnitude the value calculated for this work.Zirconium Basic Sulphate Zircomet Limited - Zirconium,,This high purity zirconium sulphate is produced by the precipitation of zirconium oxychloride.
