羟基磷灰石 (HAp) 通过 Ca(EDTA) 络合物在磷酸根离子存在下分解而合成。离子浓度比之前报道的要高得多。该途径允许在低于 140 摄氏度的温度和不同的 pH 值下形成 HAp。通过FTIR、SEM、XRD和EDS研究了所得产物的物相鉴定、结晶度和形貌。 (C) 2004 Elsevier Ltd. 保留所有权利。
Hydroxyapatite (HAp) was synthesized through the decomposition of a Ca(EDTA) complex in presence of phosphate ions. Ion concentrations are much higher than previously reported. This route allows the formation of HAp at temperatures below 140 degreesC and at different pH values. Phase identification, crystallinity and morphology of the obtained products were studied via FTIR, SEM, XRD and EDS. (C) 2004 Elsevier Ltd. All rights reserved.
