FIELD: chemistry.

SUBSTANCE: invention pertains to modified silane oxide or silica filler, the method of obtaining it and its use. The modified silane oxide or silica filler consists of a fraction with grain size less than 75 mcm with percentage mass ratio less than 15%, and average particle size from 130 to 500 mcm. The proposed filler is obtained from reaction of at least one micro-grained oxide or silica filler in a liquefied gas with at least one silane. The modified silane oxide or silica filler can be used as lacquer, coating, cosmetic products, synthetic materials and rubber.

EFFECT: obtaining of dust-free modified silane filler, without use of water and organic solvents.
