Silica gel
Silica gel packet

Description

Amorphous powder or granules of Silica. Silica gel is chemically inert, very porous and hygroscopic. It is used as a pollutant sorbent and as a humidity buffering agent. Silica gel absorbs moisture in humid environments and releases water in dry air. Once equilibrated to set moisture level, silica gel will maintain that humidity level in a closed environment. Examples of silica gel products preconditioned as humidity buffers are Art-Sorb®, Arten gel and GORE-TEX® silica tiles. Silica gel that is saturated with water can be dried by heat (110-200 C) and used again. Some brands of commercial silica gel include cobalt chloride as a humidity indicator (blue when dry and pink when moist). Silica gel has also been used as a desiccant in Dri-die cockroach formulation.

Synonyms and Related Terms

amorphous silica; gel de silice (Fr.); Britesorb [PQ Corp.]; Dri-die; Art-Sorb® [Fuji Silysia]; GORE-TEX® silica tiles; Arten gel; Arten tiles; dessicant
