Development and Characterization of Lithium-Releasing Silicate Bioactive Glasses for Bone Repair

摘要

From these experiments it can be speculated that the addition of Li to the glasses causes a decrease in their glass transition, as evidenced by the softening of the BG particles at lower temperatures and an earlier densification with an increasing proportion of Li in the glass increases. Furthermore, the addition of Li did not impair the bioactivity of the Li-BGs as evidenced by the deposition of a layer of HA on the surface of samples immersed in SBF, however further studies are necessary to fully ascertain the effect of Li ions on the bioactivity of Li-BGs and to monitor Li release kinetics in suitable media.
