Hydrothermal synthesis of various carbonate containing calcium hydroxyapatites

Carbonate containing hydroxyapatites were prepared hydrothermally between 2000 and 20,000 psi and 250 and 900°C using H 2O or CO 2 pressure. On the basis of IR, x-ray and chemical investigations it is shown that under these conditions the CO 3 triangle can replace both the OH group and PO 4 tetrahed...

Description
Summary:Carbonate containing hydroxyapatites were prepared hydrothermally between 2000 and 20,000 psi and 250 and 900°C using H 2O or CO 2 pressure. On the basis of IR, x-ray and chemical investigations it is shown that under these conditions the CO 3 triangle can replace both the OH group and PO 4 tetrahedron in the apatite structure. Replacement is possible either in only one of these positions or also combined. The extent of the solid solubility, however, is still unknown.
