摘要

采用热分解法从鸵鸟皮质骨中提取一种新型天然羟基磷灰石(HAp)生物陶瓷。利用热重分析(TGA)、傅里叶变换红外光谱(FTIR)、x射线衍射(XRD)和扫描电镜(SEM)等分析工具对HAp进行了表征。通过热重分析证实了骨粉中有机杂质的去除。羟基磷灰石的FTIR光谱证实了生物陶瓷中主要官能团如磷酸(po43 -)、羟基(OH-)和碳酸盐(co32 -)的存在。XRD分析表明HAp为骨粉950℃煅烧后的结晶相,SEM分析证实HAp具有典型的片状结构。

Extraction and Characterization of Novel Natural Hydroxyapatite Bioceramic by Thermal Decomposition of Waste Ostrich Bone.

A novel natural hydroxyapatite (HAp) bioceramic was extracted from the ostrich cortical bone by the thermal decomposition method. HAp was characterized by different analytical tools such as thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) analysis, and scanning electron microscopy (SEM). Removal of organic impurities from the bone powder was confirmed by TGA analysis. FTIR spectra of HAp confirmed the presence of the major functional groups such as phosphate (PO4 3-), hydroxyl (OH-), and carbonate (CO3 2-) in the bioceramic. The XRD data revealed that the HAp was the crystalline phase obtained by calcination of the bone powder at 950°C, and the SEM analyses confirmed the typical plate-like texture of the nanosized HAp crystals.
