A polymeric sol-gel combustion method has been used to synthesize nanocrystalline hydroxyapatite (HA) powder from calcium nitrate and triethyl phosphate with the addition of NH(4)OH. The sol-gel combustion process generates phase-pure nanocrystalline HA powder, as characterized using Fourier transform infrared (FTIR), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Sintering of the HA powder compact at 1200 degrees C for 2 h leads to a 93% theoretical dense ceramic body. This method offers an easy route for the preparation of phase-pure nanocrystalline HA powder.
采用聚合物溶胶 - 凝胶燃烧法，以硝酸钙、磷酸三乙酯为原料，并添加氢氧化铵来合成纳米晶羟基磷灰石（HA）粉末。溶胶 - 凝胶燃烧过程生成了相纯的纳米晶HA粉末，通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和透射电子显微镜（TEM）对其进行了表征。将HA粉末压块在1200℃下烧结2小时，得到了理论密度为93%的陶瓷体。该方法为制备相纯的纳米晶HA粉末提供了一条简便途径。
