SODIUM ZIRCONIUM CARBONATE AND ZIRCONIUM BASIC CARBONATE AND METHODS OF MAKING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method of producing zirconium phosphate.SOLUTION: The method for producing zirconium phosphate includes: making a mixture of zirconium oxychloride and soda ash; and heating the mixture at a sufficient temperature and for a sufficient time to form sodium zirconium carbonate. Afterwards, the sodium zirconium carbonate is treated with a caustic soda to form alkaline hydrous zirconium oxide. The alkaline hydrous zirconium oxide is then mixed and heated with a phosphoric acid to form acid zirconium phosphate. Afterwards, the acid zirconium phosphate is titrated using a caustic soda to obtain desired zirconium phosphate.
