FIELD: chemistry.
SUBSTANCE: invention relates to precipitated silicic acid and a method of obtaining said acid. Precipitated silicic acid has coefficient of extinction SiOHizolir equal to or greater than 1. The silicic acid is obtained through reaction of a silicate with an acidic substance. The obtained silicic acid is then filtered, washed, dried and annealed.
EFFECT: silicic acid in silicone rubber compositions provides high stability during storage, high strength and optimum fluidity characteristics.
