Abstract

To prepare hydroxyapatite at low temperatures, several kinds of calcium carbonate powders and single crystal calcite were reacted with diammonium hydrogenphosphate. In the case of calcium carbonate powders, hydroxyapatite was produced after the reaction at 40°C for 4 h. In the case of single crystal calcite, althouth the products were observed on calcite surface, identification of the products was not simple.
