摘要
根据ISO 13779-3和JIS T 0330-3对作为生物材料的磷酸钙进行粉末性能评价和检验。采用x射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、扫描电镜(SEM)、比表面积测量(SSA)、粒度分析和化学分析等方法研究了粉末的性能。晶体含量和化学杂质通过基于ISO 13779-3的检查来评估，溶解度通过基于JIS T 0330-3的检查来评估。这些结果表明，我们的产品是单相的，晶体含量和化学杂质在规格范围内。此外，根据合成方法的不同，羟基磷灰石的颗粒形态和SSA具有不同的特征。通过对溶解度的测定，证实了我们的产品在每个比表面积上的钙离子洗脱量是不同的。因此，这些产品有望作为生物材料的原材料，并通过应用我们的技术来提供所需的产品。(2016年10月25日收稿;接受2016年2月17日)
EVALUATION OF POWDER PROPERTY OF CALUCIUM PHOSPHATE
The evaluation of powder properties and the examination based on ISO 13779-3 and JIS T 0330-3 for calcium phosphates as biomaterial were performed. Powder properties were investigated by X-ray diffractometry (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), measurement of specific surface area (SSA), particle size analysis and chemical analysis. Crystalline content and chemical impurities were evaluated by the examination based on ISO 13779-3, and the solubility was evaluated by the examination based on JIS T 0330-3. These results indicated that our products were single phase, and crystalline content and chemical impurities were within the range of specification. Moreover, it was found that hydroxyapatite has different characteristics for particle morphology and SSA according to the difference of synthesis methods. It was comfirmed that the elution amounts of calcium (Ca 2+ ) ion per each specific surface area were different among our products from the examination of solubility. Consequently, these products are expected as raw materials for biomaterials, and the requiered products will be supplied by the application of our technology.
