摘要：

The stability of sintered hydroxylapatite particles was studied in glass matrices of the system SiO2-CaO-P2O5-Na2O-Al2O3-B2O3 at sintering temperatures between 700 and 1000-degrees-C. The results from X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDX) analysis, transmission electron microscopy (TEM) and electron diffraction showed that above 700-degrees-C the Na+ ions diffuse into the hydroxylapatite particles which then transform into rhenanite. The glass matrix undergoes crystallization yielding wollastonite crystals and a silica rich matrix.
