A mixture with different compositions of HA and TCP were synthesize in this work by precipitation method using Ca(NO3)2 4H2 and (NH4)2HPO4 as the starting materials. A mixture with HA and TCP phases in different ratios were produced. The powders were sintered from 1000 degrees C to 1250 degrees C. The phase compositions of the mixtures were then studied via XRD. This work shows that the pH value determines the different phase compositions of the HA-TCP mixture. Chemical analyses were carried out by FTIR. The microstructure was observed under SEM.
在本工作中，以Ca(NO₃)₂·4H₂O和(NH₄)₂HPO₄为原料，采用沉淀法合成了具有不同HA和TCP组成的混合物。制备出了具有不同比例HA和TCP相的混合物。将这些粉末在1000℃至1250℃下进行烧结。然后通过XRD研究混合物的相组成。本工作表明，pH值决定了HA-TCP混合物的不同相组成。通过FTIR进行化学分析。在SEM下观察微观结构。
