Abstract

Bioglass is a good bioactive material and has been used in many medical fields, include drug delivery systems, non-load-bearing implants and bone cements. Sol-gel is a good method in the preparation of coating materials. It also can be used in the preparation of bioactive glass. In this paper, the principles and technical processes are introduced. The effects on characteristics of bioactive glasses of the factors such as H2O dosage, ethanol dosage, gel temperature and activator are analyzed in detail. The research progress in preparation of sol-gel bioactive glasses is summarized. Finally the development foreground of sol-gel bioglass is also expected.
