Crystal growth of carbonate apatite using a CaCO3 flux

J Mater Sci Mater Med. 1999 Sep;10(9):561-6. doi: 10.1023/a:1008972432076.

Abstract

Single crystals of carbonate apatite were grown using a CaCO3 flux under an Ar gas pressure of 55 MPa. The crystals obtained were observed by scanning electron microscopy, optical microscopy and X-ray diffraction. Electron probe microanalyses and thermal analyses were performed. CO3 ions in planar triangle form replaced both OH sites and PO4 tetrahedral sites in the apatite structure: in particular, the OH sites were perfectly substituted by CO3 ions using this method.
