Abstract:
A cyclic process for the preparation of barium sulphate and lithium-iron phosphate comprising (i) preparing an aqueous solution containing lithium and sulphate ions and (ii) adding solid barium hydroxide at a temperature of more than 50° C., wherein the barium hydroxide is added over a period of less than 15 minutes. Also, barium sulphate obtainable by the process according to the invention.
