Choice of the structural parameters upon developing chemical compositions of glass microspheres

The analysis of some parameters that determine the structure of glasses, which must be taken into account when designing the chemical compositions of microspheres, including molar volume, silicate modulus (in the case of silicate glasses), gas permeability coefficient, structure connectivity factor. In addition, an "internal porosity" parameter has been proposed. Tab. 1, ill. 1, bibliography: 9 titles.
