- Synthesis of hexaphosphate by hydrolysis of cyclo-hexaphosphate
-
Sodium and ammonium hexaphosphates were prepared by hydrolyzing cyclo-hexaphosphate in a 10M sodium hydroxide solution at -7°C for 20h. Sodium hexaphosphate was amorphous and unstable at room temperature. Ammonium hexaphosphate was crystalline and stable at room temperature.

- The preparation and properties of the twelve-membered ring hexametaphosphate anion
-
A true hexametaphosphate anion was prepared and some of its physical properties were measured. The hydrolysis rates for the ring opening to sodium hexapolyphosphate were determined at 30 and 60° at pH values of 4, 7, and 11. X-Ray powder patterns were obtained for the following salts: Na6P6O18, Na6P6O18·6H2O, Li6P6O18, and Li6P6O18·6H2O.
