Hydrothermal Synthesis of Hydroxyapatite – Polymer Composite Materials

The hydrothermal syntheses of hydroxyapatite and polymer composite materials were studied. The apatite precursor slurry was prepared by agitating a mixture of CaCO3 and CaHPO4·2H2O, and 3 kinds of polymeric fibers were added. The mixture was treated under hydrothermal conditions at 180 °C for 5 hours. The XRD patterns of the products showed that the products were well-crystallized hydroxyapatit...
