Solid composites of calcium phosphates and hydroxypropylmethylcellulose (HPMC) were prepared at temperatures of 121 degrees C. Three biologically relevant calcium phosphates were studied: CaHPO(4). 2H(2)O (DCPD), calcium deficient apatite (CDA), and biphasic calcium phosphate (BCP). Properties of the solid composites obtained were studied with FTIR, X-ray diffraction, and SEM techniques. Special attention was devoted to seeking a possible chemical interaction between calcium phosphates and HPMC. No interaction was found. Thus, HPMC was proven to have no influence on chemical properties of calcium phosphates.
在121摄氏度的温度下制备了磷酸钙与羟丙基甲基纤维素（HPMC）的固体复合材料。研究了三种具有生物学相关性的磷酸钙：磷酸二氢钙二水合物（DCPD）、缺钙磷灰石（CDA）和双相磷酸钙（BCP）。利用傅里叶变换红外光谱（FTIR）、X射线衍射和扫描电子显微镜（SEM）技术研究了所得固体复合材料的性能。特别关注了寻找磷酸钙与HPMC之间可能的化学相互作用。未发现相互作用。因此，证明HPMC对磷酸钙的化学性质没有影响。
