FIELD: chemistry. ^ SUBSTANCE: hydrophobic silicon dioxide was obtained pyrogenically, by oxidation in the flame or (which is more preferentially) by hydrolysis in the flame; it contains potassium in the range from 0.000001 to 40 wt %. Silicon dioxide potassium-doped with aerosol hydrophobic can be superficially modified using one or more compounds. The method of such silicon dioxide obtaining and the silicon rubber containing the latter as filler are claimed. ^ EFFECT: increase of cut-growth resistance and transparency after curing of the liquid rubber mixture. ^ 8 cl, 6 tbl, 6 ex |
