摘要

摘要本文对羟基磷灰石粉体的合成进行了比较研究。选择化学共沉淀法合成该生物材料。采用x射线衍射、红外光谱(FTIR)、动态光扩散DLS技术和扫描电子显微镜(sem)对制备的粉末进行了结构、尺寸和形貌分析。所得结果与市售羟基磷灰石粉末所得结果进行了比较。研究方法证实了一种具有最佳结晶度和结晶度的高纯度羟基磷灰石的合成，可用于硬组织的重建和再生。

Comparative Study of Bioceramic Powders Synthesis Based on Calcium and Phosphates

Abstract In this paper is presented a comparative study regarding the synthesis of hydroxyapatite powders. The chosen method of synthesis of this biomaterial was chemical co-precipitation. The structure, size and morphology of the obtained powders were analyzed by X-ray diffraction, infrared spectroscopy - FTIR, dynamic light diffusion DLS tehnique and scanning electron microscopy-SEM. The results obtained were compared with those obtained on a commercial hydroxyapatite powder. Investigation methods have confirmed the synthesis of a high purity hydroxyapatite with a optimal degree of crystallization and crystallinity for the reconstruction and regeneration of hard tissue.
