摘要： 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.

Abstract: With hydroxyapatite nanoparticles as the starting material, porous hydroxyapatite nanosolid was prepared by a unique solvothermal hot press method. The samples were characterized by X-ray diffraction, scanning electron microscope and thermal analysis method. The effects of solvent species and the uniformity of the distribution of solvents on the pore volume and pore radius of the porous hydroxyapatite nanosolids were investigated. Besides, the thermal stability of the porous hydroxyapatite nanosolids was also examined.
