The soluble glass contains antibacterial metal ions selected from the group consisting of Ag+, Cu+, Cu2+ and Zn2+. The antibacterial ions contained are forming a solid solution with the components of soluble glass and elute along with the dissolution of the soluble glass skeletal network. The eluting rate of metallic ions is determined by the dissolving rate of the soluble glass and is not affected by the environmental concentration of alkaline metal ions, such as Na+. | |
