利用溶剂热压方法,以羟基磷灰石(HAP)纳米颗粒为原料制备了一种介于纳米粉体和纳米陶瓷体之间的过渡态——体块HAP多孔纳米固体,并用X射线衍射(XRD)、扫描电子显微镜(SEM)、压汞仪和热分析(DSC和TGA)等方法对样品进行了表征,初步研究了溶剂的种类、分布均匀性等因素对HAP多孔纳米固体的孔容和孔径分布的影响,并对HAP多孔纳米固体的热稳定性进行了分析. A HAP nanoporous solid was used as a transitional state between nanopowders and nanocrystalline ceramics by hydrothermal method using hydroxyapatite (HAP) as raw material. X-ray diffraction (XRD) XRD, SEM, mercury porosimetry and thermal analysis (DSC and TGA) were used to characterize the samples. The effects of solvent type, distribution uniformity and other factors on the pore volume of porous nano-solid HAP Pore ​​size distribution, and the thermal stability of HAP porous nano-solid was analyzed.
