Strontium and barium tetraphosphates were made by hydrolyzing cyclo-tetraphosphate in a 5 mol dm−3 solution of sodium hydroxide, neutralizing the phosphate solution with 1 mol dm−3 hydrochloric acid, and then adding an aqueous solution of strontium or barium chloride to the solution. The P/M (M: Sr or Ba) ratio of the tetraphosphates was 1.3. The strontium and barium tetraphosphates were X-ray diffractometrically
