Research on the basis of foam glass substrates with additions of copper compounds

Abstract

Obtained artificial substrates, representing a porous glass (foam glass) with additives of 3 to 10% of the mass. copper ions. Glass raw materials were used as raw materials for the synthesis of substrates. In order to create open porosity, a carbonate blowing agent (chalk) was introduced into the initial mixture. Foaming additive served as sodium nitrate, a source of copper ions - copper sulfate (copper sulfate). A distinctive feature of the synthesis method was the combination of wetting the initial mixture and its rapid heating to maximum temperature. This mode was used to increase the porosity of the resulting structure. It was found that the water absorption of the obtained substrates increases with an increase in the concentration of copper ions in them. The resulting materials, due to the increased content of copper ions in them, may have a fungicidal effect. Perhaps their use in crop production, landscape design, the construction industry in conditions of high humidity.
