Microporous materials were obtained by pyrocarbon modification of matrices based on a highly dispersed silicon dioxide. The modification involved polystyrene carbonization at 400 and 700°C in an argon flow. The possibility was elucidated of varying the properties of porous materials (density, porosity, sorption of organic solvents, and compression strength) by varying the way of introduction of polystyrene solutions into the matrix and their concentrations.
