Abstract: Non-agglomerating elastomeric organopolysiloxane particulates having a mean particle size ranging from 50 .mu.m to 3 mm, uniformly coated with silica powder on the face surfaces thereof and well adapted as a soft filler material for natural or synthetic polymers or as a controlled release dosage form, are produced by (a) forming an oil-in-water emulsion of .alpha.,.omega.-dihydroxydiorganopolysiloxane oils, silica powder, a platinum curing catalyst and, optionally, an active principle such as a medicament or an agrochemical, and then (b) breaking and polycondensation crosslinking such emulsion into the desired particles by heating it to a temperature ranging from 40.degree. to 100.degree. C.
