Abstract
A new synthesis is disclosed which produces synthetic crystalline hydroxyapatite. The process comprises reacting anhydrous trisodium phosphate wih calcium chloride in a formamide/water solution. Good yields of hydroxyapatite are obtained quickly, simply, and at low temperatures.
Claims4
A process for preparing crystalline hydroxyapatite comprising contacting a source of calcium ions with about a stoichiometric amount of anhydrous trisodium phosphate in a combination solvent comprising from about 10 to about 75 weight percent of a polar, aprotic organic solvent and from about 25 to about 90 weight percent of water and thereafter recovering said crystalline hydroxyapatite.
