【Abstract】 According to the structure characteristics of natural bone,the hydroxyapatite bionic bone material was prepared.The variations of microstructure and properties of the material with sintering conditions were studied.The results showed that the gradient structure of the material was similar to that of natural bone;sintering temperature and time influenced the porosity and grain size,which caused some changes in the strength of the material.更多还原
