Description

A jelly-like semi-solid material composed of hydrated silicon dioxide. Silicic acid, or hydrated silica, is prepared by acidifying a solution of sodium silicate. When dried, silicic acid forms amorphous lumps that are called silica gel. Hydrated silica is used for paper and textile coatings.

Synonyms and Related Terms

hydrated silica; silica gel (hydrated)
