The quantum chemical calculations on the spatial and electronic structure of phosphorus-containing radical sites of aerosil surface have shown a good opening of the use of chemically modified silica materials as cheap fire extinguishing compositions. Their effectiveness is conditioned by low destruction energy of surface compounds as compared with the dissociation energies of the molecules of relative modifiers. A consequence of the elementary steps has been substantiated theoretically for the inhibiting flame active centers due to effect of silica surface sites.
