  • bioactive glass differs from conventional lime-sodium-silicate glasses in that it binds living tissue.
  • Bioactive glass refers to a glass that forms a firm bond with body tissue, forming a layer of hydroxyl apatite.
  • the object of the invention is to provide glass powder from glass compositions which avoid the disadvantages of the prior art, in particular can be produced without great effort.
  • a glass powder is understood to mean a powder comprising a large number of glass particles of any shape, including a glass fiber, for example a glass ball with a particle size of ⁇ 1 mm, preferably ⁇ 500 ⁇ m, or a glass fiber with a diameter of ⁇ 1 mm, preferably ⁇ 500 ⁇ m.
  • the glass powder can be added to products.
  • the glass powders are obtained by grinding in different grinding media.
  • the glass compositions of the glasses can be produced on an industrial scale using standard processes and are suitable, for example, for grinding in water, since the glass compositions have sufficient hydrolytic resistance, in contrast to glasses which contain a lot of phosphate, for example.

  • Glass powder comprising ion-exchangeable glasses according to the invention have an antimicrobial effect in aqueous media by increasing the pH value by ion exchange between a metal ion, such as an alkali metal or alkaline earth metal ion and the H + ions of the aqueous solution, and by ion-induced impairment of cell growth (osmotic pressure, Disruption of metabolic processes in the cells).
  • Ground glass powder with particles of small particle size and large surface area show a drastic increase in reactivity, which, due to the ion exchange already described, results in a strong antimicrobial effect.
  • the antimicrobial effect in the glass powders according to the invention is achieved by the ion exchange and not by the antimicrobial effect of the heavy metal ions. However, these can increase the antimicrobial effect as an additive.

  • Na 2 O is used as a flux when melting the glass. At concentrations less than 5%, the melting behavior is negatively affected. In addition, the necessary mechanism of ion exchange no longer works sufficiently to achieve an antimicrobial effect. At Na 2 O concentrations higher than 30% by weight, a deterioration in the chemical resistance or hydrolytic resistance can be observed, especially in connection with a decrease in the SiO 2 content.
  • Alkali and alkaline earth oxides can in particular be added to increase the ion exchange and thus to increase the antimicrobial effect.

  • ZnO is an essential component for the hot-forming properties of the glass. It improves crystallization stability and increases surface tension. It can also support the antimicrobial effect. With low SiO 2 contents, it increases the crystallization stability. To achieve an antimicrobial effect, up to 8% by weight of ZnO can be present.

  • components such as fluorine can be added to the glass up to a total concentration of 5% by weight.
  • the glass powder described in this invention is not water-soluble, but acts primarily by ion exchange or ion release, which is associated with a surface reaction, pH increase and metal ion release.

  • the glass was smelted from the raw materials in a platinum crucible at 1600 ° C and processed into semi-finished products or ribbons.

  • Trace elements are, for example, impurities contained in the glass, such as Fe 2 0 3 , K 2 O ; usual refining agents, for example Sb 2 O 3 , As 2 O 3 .
  • compositions according to the invention show an antimicrobial or biocidal action after grinding, for example to give a glass powder. This is surprising for the person skilled in the art, since glasses with a phosphorus content of less than 1% by weight based on oxide, for example soda-lime glasses, are unreactive as glass. A biocidal effect was only attributed to glasses containing phosphorus with a phosphorus content> 1% by weight, since these glasses are considered to be very reactive.
