Abstract
The issue of waste-free use of mineral raw materials is crucial for the national economy. Mica- and glass-based composites combining high dielectric properties with chemical, thermal and mechanical strength are of special significance. For about fifty years, domestic composite materials have been based on aluminum borosilicate glass containing fluoride compounds which are harmful substances polluting the environment and worsening working conditions. The paper presents data on the uses of glass production waste and mica deposit waste for producing new composite materials which have better ecological characteristics and require lower production costs. It was identified that mica wetting depends on the chemical composition of the crystalline substance. The quantitative content of acidic oxides and the difference between the content of acidic and basic oxides have the greatest impact on the temperature interval of wetting.
