摘要
The invention relates to a color-stable, antimicrobial glass powder, obtained by partial ion exchange at a temperature of 300 to 350 ° C and a replacement time of 1 to 120 minutes consisting of a mixture of: - Porous glass particles with micropores and macropores from continuously foamed by extrusion borosilicate glass with a Fe 2 O 3 content 0.2 wt .-%, wherein the glass foam obtained then comminuted by dry milling to average particle sizes of 1.0 to 8.0 microns becomes, Color stabilizers containing from 0.1% to 0.2% of ammonium ions, - Antimicrobial metal ions from dissolved metal salts, wherein the metal ions may be silver and / or zinc and / or copper ions.
