obtained, with silver ions doped, antimicrobial, porous glass powder, as well as a method for the manufacture of such a at high temperatures and its use

摘要

The present invention relates to a obtained, an 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 by means of extrusion continuously foamed borosilicate glass having an fe₂O₃-Content of 0,2 w -%, wherein the resulting glass foam, subsequently, by dry milling on average particle sizes of 1,0 to 8,0 μm is comminuted,Colour stabilisers, the 0,1% to 0,2% ammonium ions,antimicrobial metal ions from dissolved metal salts, wherein the metal ions silver - and / or zinc - and / or copper ions can be.n="31"
