摘要
结合溶胶凝胶法可制得成分高度均匀的湿凝胶和自蔓延法可简单快捷地制得超细粉的优点 ,提出利用溶胶凝胶自蔓延法制备多元生物玻璃超细粉。对制得粉末的性能和形貌进行了分析 ,并与高温熔化法和溶胶凝胶法制得的粉末进行了对比。实验结果表明 :利用溶胶凝胶自蔓延法可快速制得成分均匀的生物玻璃前驱粉 ,粉末的粒径分布范围窄 ,平均粒度为 2 0 0nm。此外 ,该种粉末还具有优秀的压制性能。
Based on the combination of Sol-Gel and Self-propagating synthesis, a new chemical process, termed SGS process, has been developed to synthesize ultrafine bioglass powder. Characteristic of powder has been analyzed by XRD, TEM and Laser granularity analyzer. Experiment results showed that bioglass precursor powder could be manufactured rapidly and conveniently by SGS process. Compared with HTM powder and SG powder, SGS powder has more homogeneous composition and ultrafine particles(～200nm). In addition, the powder can be formed easily under pressure.
