Abstract
The modeling of various modes of formation of microporous silica using high-pressure helium was carried out by the methods of molecular dynamics. It is shown that by controlling the helium pressure in the process of quenching the silica melt, the structure of the obtained glasses can be changed continuously and within wide limits. The density of the obtained glasses varies in the range from 2.2 to 1.5 g / cm3 and the Ostwald solubility coefficients for helium and neon are more than an order of magnitude
