A gallium silica glass composition is described. The glass can be used in variety of biomedical applications.

A sol-gel bioactive glass precursor, method for making sol-gel glasses, resultant sol-gel bioactive glasses, and methods of use thereof, which include introducing Na.sub.2O into the glass network during the sol-gel process through the use of Na-ethoxide, NaCl, or sodium silicate rather than sodium nitrate. Medical and industrial uses of such glasses.

Acid-resistant and biosoluble glass compositions and products made therefrom. The glass compositions exhibit acid resistance, durability in white water as may be used in a wet laid fabrication process, and good biosolubility. In another aspect, a glass fiber mat is made from such a glass composition, and may be used in the manufacture of lead-acid batteries, for example as a pasting material or battery separator.

Provided is an antimicrobial glass which can be accommodated in a narrow accommodation space of an antimicrobial water unit for supplying antimicrobial water to a washing tub of a washing machine, and also can effectively suppress an occurrence of black mold or the like in a washing tub and can effectively protect a subject for washing against microbes while suppressing the coloration of the subject.

As an antimicrobial glass for exhibiting an antimicrobial effect by releasing silver ions when brought into direct contact with water, when the total amount is 100% by weight, the content of Ag.sub.2O has a value within the range of above 5% by weight but less than 10% by weight, the content of P.sub.2O.sub.5 and CaO has a value within a predetermined range, the content of ZnO has a value of below 10% by weight, the content of K.sub.2O, Al.sub.2O.sub.3, and MgO has a value within a predetermined range, and the antimicrobial glass has a tablet shape with a maximum diameter value in a predetermined range.

A pelletized expanded glass material is provided, which is particularly suitable as a growth support for microorganisms, especially for use in a biogas plant or an anaerobic sewage treatment plant. The production process of the invention for the pelletized expanded glass material contains the steps of: mixing a ground glass, an expanding agent and a binder to give a starting mixture. The starting mixture is pelletized to give ground glass pellet green bodies. The ground glass pellet green bodies are foamed to give expanded glass pellet particles at temperatures of 600 to 950 C. Accordingly, especially in the production of the starting mixture, minerals and or trace elements are added, which serve especially for the nutrient supply of microorganisms used in the biogas plant or the anaerobic sewage treatment plant.

A material that is less populated by biofilms than known materials and is well tolerated by the body is provided. The material is an element introducible into or attachable on a human or animal body and includes a glass and/or glass ceramic and/or ceramic material at least in some areas thereof, which inhibits the formation of biofilms and/or on which human or animal cells grow if the element is introduced into the human or animal body or attached thereto, wherein the glass and/or glass ceramic material comprises at least: SiO.sub.2 in a range from 60 to 75 wt % and ZnO in a range from 1 to 7 wt %.

Acid-resistant and biosoluble glass compositions and products made therefrom. The glass compositions exhibit acid resistance, durability in white water as may be used in a wet laid fabrication process, and good biosolubility. In another aspect, a glass fiber mat is made from such a glass composition, and may be used in the manufacture of lead-acid batteries, for example as a pasting material or battery separator.

The present disclosure relates to mesoporous glasses as well as uses of such glasses, for example, as hemostats

A material that is less populated by biofilms than known materials and is well tolerated by the body is provided.
