Abstract

Using X-ray diffraction analysis, transmission electron microscopy, and complex thermal analysis, it was shown that brushite crystals are formed from aqueous solutions of ammonium hydrogen phosphate and calcium nitrate. The hydrothermal treatment of brushite results in the formation of quasi-one-dimensional hydroxyapatite nanoparticles, the longitudinal size of which is about 400 nm, and the transverse size is 40 nm. It was demonstrated that hydroxyapatite nanoparticles can be used as fillers of composite matrices for tissue engineering, in particular, in bone grafting.

水热条件下各向异性羟基磷灰石颗粒的形成

摘要

使用X射线衍射分析，透射电子显微镜和复杂的热分析，表明透钙磷石晶体是由磷酸氢铵和硝酸钙的水溶液形成的。透钙磷石的水热处理导致形成准一维羟基磷灰石纳米颗粒，其纵向尺寸为约400nm，横向尺寸为40nm。已证明羟基磷灰石纳米颗粒可以用作组织工程尤其是骨移植中的复合基质的填料。
