A／W生物活性微晶玻璃的制备

生物活性玻璃陶瓷材料由于能够与活体组织自发产生紧密的化学键合而成为骨修复材料中的重要分支，其中A／W生物微晶玻璃更是由于在保持良好生物活性的基础上，力学性能接近甚至超过自然骨而作为承重的生物活性材料应用于临床。采用正硅酸乙酯和磷酸三乙酯，利用溶胶-凝胶法制备玻璃粉体，这种玻璃粉体经过一定的热处理工艺可以得到含有磷灰石和硅灰石的A／W生物微晶玻璃。

Preparation of A/W Bioactive Glass-Ceramic

As bioactive glass and ceramics can be bonded to form living tissue and bone spontaneously,they have become important branches of bone repair materials.Among them,A/W microcrystalline bioglass has been used in clinical operations as loading biomaterial,because not only they have high bioactive,but also their mechanical properties are close or exceed to human bone.Using triethy phosphate and ethyl silicate,glass powder was get on sol-gel method.After a certain heat treatment process on this glass powder,A/W ...
