Porous glass-ceramics with bacteriostatic properties in silver-containing titanium phosphates: control of release of silver Ions from glass-ceramics into aqueous solution

摘要

Porous glass-ceramics with the surface phase consisting predominantly of AgTi_2(PO)_4_3 crystal and the interior phase of LiTi_2(PO_4)_3 crystal are prepared by exchange of Ag+ ions for Li+ ions. In the present work, the release of Ag+ ions from glass-ceramics into aqueous solutions was Investigated. Exchanged Ag+ ions were chemically stable in Water.
