FIELD: chemistry.
SUBSTANCE: present invention relates to modified silicon dioxide, a method for production thereof and use thereof. Modified silicon dioxide has the following physical and chemical parameters: CTABmod-surface: less than 200 m2/g, BET MR-surface: 50 m2/g to 500 m2/g, CTABmod-surface - BET MR-surface: less than 0 m2/g, C content: more than 0.5 wt.%, modemod according to particle size determination in CPS centrifuge: more than 50 nm, D75,mod according to particle size determination in CPS centrifuge: from 20 nm to 150 nm, Rmin according to pore size determination by mercury porosimetry, in a compacted state: less than 10.0 nm, sulphur content: not more than 1.50 wt.%.
EFFECT: disclosed is silicon dioxide, having improved processability of mixtures containing it with improved dynamic properties, as well as improved quality of dispersion of ingredients.
