Silica Gel

Silica Gel is an amorphous and porous form of silicon dioxide. It is a rigid 3D network of colloidal silica whose voids may contain liquid or gas. Silica gel is classified as aquagel (pores are filled with water), xerogel (by evaporation, the aqueous phase in the pores is removed), and aerogel (solvent removed by supercritical extraction).
Typical Physical Properties

100-200 mesh Grade (Davisil® Grade 923):

Pore size: 0.40 cm3/g pore volume, 30 Å
Surface area: 430-530 m2/g
Bp: 2230 ºC
Mp: >1600 ºC
SMILES string: O=Si=O
Davisil is a registered trademark of W.R. Grace & Co.

Typical Applications

Depending on the size of the crystal, silica gel has various uses. It can act as a desiccant and food additive and can be used in cat litter. In chemistry, silica gel is used in chromatography as a stationary phase. Other uses include water filtration and as a humidity indicator.

Packaging Options

50 GM, 250 GM, and 1 KG in plastic bottles. Larger quantities are available upon request.

Sustainable Qualities

Silica Gel, also known as Silicon Dioxide, is a highly sustainable material commonly used as a desiccant in various products, including electronics, food packaging, and pharmaceuticals. Silica Gel is a bio-based material, as it is derived from silica, a naturally occurring mineral. Silica Gel is also highly recyclable, making it a valuable contributor to a circular economy. By recycling Silica Gel, manufacturers can reduce their reliance on virgin materials, conserve resources, and reduce waste.
