<p>A process for providing a zirconium basic sulfate includes providing a zirconium oxychloride solution, and then dialyzing the solution against a liquid selected from water and an aqueous solution across at least one anion exchange membra ne to provide a dialyzate and diffusate. The dialyzate includes at least 90 percen t of the zirconium ions of the zirconium oxychloride chloride solution and has a tota l acidity that is lower than the original zirconium oxychloride solution. A precipitate including zirconium basic sulfate may be formed from at least a portion of the diffusate. The zirconium oxychloride solution may be provided, for example, by dissolving zirconium tetrachloride in one of water and a hydrochloric acid solution. A material including zirconium basic sulfate produced by the process of the invention also is disclosed.</p> |
