    • An antibacterial phosphate glass composition contains phosphorous pentoxide at 45-90 wt.% on an oxide basis together with a range of other oxides such that (A) the sum of titanium dioxide + zirconium dioxide + barium oxide + lanthanum oxide + chromium oxide + niobium oxide is 0.01-40 wt.%; (B) the sum of silver oxide + zinc oxide + cupric oxide + chromium oxide + iodine + tellurium oxide + germanium oxide is 0.1-40 wt.%; and (C) the composition is free of tin. An antibacterial phosphate glass composition contains phosphorous pentoxide at 45-90 wt.% on an oxide basis together with a range of other oxides (see below) such that (A) the sum of titanium dioxide + zirconium dioxide + barium oxide + lanthanum oxide + chromium oxide + niobium oxide is 0.01-40 wt.%; (B) the sum of silver oxide + zinc oxide + cupric oxide + chromium oxide +iodine + tellurium oxide + germanium oxide is 0.1-40 wt.%; and (C) the composition is free of tin. The other oxides with their amounts by weight on an oxide basis are as follows : B 2O 3 (0-60%), SiO 2 (0-40%), Al 2O 3 (0-20%), SO 3 (0-30%), Li 2O (0- 0.1%), Na 2O (0-0.1%), K 2O (0-0.1%), CaO (0-40%), MgO (0-40%), SrO (0-15%), BaO (0-40%), ZnO (0-40%), Ag 2O (0-5%), CuO (0-15%), Cr 2O 3 (0-10%), iodine (0-10%), TeO 2 (0-10%), GeO 2 (0-10%), TiO 2 (0-10%), ZrO 2 (0-10%), La 2O 3 (0-10%), Nb 2O 3 (0-5%), CeO 2 (0-5%), Fe 2O 3 (0-5%), WO 3 (0- 5%), Bi 2O 3 (0-5%) and MoO 3 (0-5%). Independent claims are also included for (1) antimicrobial glasses or glass-ceramics and their powders, the ceramic being made from the oxide composition; (2) polymer-glass composites made from the glass and/or glass-ceramic; (3) production of the polymer-glass composites or their granulates by heating a mixture of the polymer and glass powder to 50-350[deg]C and optionally granulating; (4) production of the antimicrobial glasses by melting all of the components , including Ag 2O, ZnO and other antimicrobial components in a crucible; and (5) production of plastics (semi-finished) products by processing the polymer-glass composites.
