Watersetting cement based on hydroxylapatite and heattreated calcium monobasic phosphate

Experimental data are presented which demonstrate that hydroxylapatite, which per se cannot be cured by water, acquires the ability to set when mixed with calcined calcium monobasic phosphate. The content and extent of condensation of the phosphoric acids forming during the calcination of Ca(H2PO4)2...

Summary:Experimental data are presented which demonstrate that hydroxylapatite, which per se cannot be cured by water, acquires the ability to set when mixed with calcined calcium monobasic phosphate. The content and extent of condensation of the phosphoric acids forming during the calcination of Ca(H2PO4)2 are shown to have a strong effect on the nature and rates of the chemical and phase transformations involved and, accordingly, on the properties of the resulting cement. The calcination conditions are optimized to obtain materials suitable for eliminating injuries to dental and bone tissues.
