Ammonium polyphosphate forms II, V, and VI have been prepared by new preparation processes using ammonium orthophosphate, urea and/or phosphorus pentaoxide as starting materials. The preparation processes are very useful for a large scale preparation

Calcium phosphate cements were prepared by mixing α-type calcium phosphate, aqueous solutions of polyvinyl alcohol and citric acid, and silicate sand. Higher concentration of polyvinyl alcohol and citric acid gave a cured body having higher mechanic

Preparations of small-ring and short-chain condensed phosphates were made by dry and wet processes, respectively. The crystallization of tetra- hexa-, and octaphosphates from the phosphate solution was not easy, and metal salts of these oligophosphat
