Influence of temperature and Cl on the hydrothermal replacement of calcite by apatite and the development of porous microstructures

Calcite (CaCO3) powder was replaced by hydroxylapatite [Ca 5(PO4)3OH] in hydrothermal experiments at temperatures between 120 and 180 °C, and times between 2 and 12 h, in 1.0 M (NH4)2HPO4 solutions. Additional experiments using concentrations of up to 2.0 M NH4Cl as an additional component were carr...
