Abstract
The obtaining of elastomers-reinforcers silica powders from SiO2 alkal i hydrosols was studied. The conditions of obtaining and maturation of hydrosol were established : temperature, degree of neutralization, Si O2 concentration, concentration of dispersing agent added to the solut ion, time of ageing. The powders obtained were characterizated from th e point of view of oil index, specific surface, porosity and apparent density.
