Abstract

The thermodynamics analyse of systems of Ca-P2O5-H2O and Ca(OH)2-H3PO4-H2O in the water solution when synthesize hydroxyapatite using Sol-gel method was made. The relation figure of distributing coefficient of phosphorous acid and all the phosphorous acid radical hydroniums in the water solution and PH value and the relation figure of lg[Ca]T and PH value were drawn, and the appropriate condition to synthesize hydroxyapatite was get.
