calcium silicate Chemical Properties,Uses,Production

Description

Calcium orthosilicate is commonly used as a safe alternative to asbestos for high-temperature insulation materials. Industrial grade piping and equipment insulation are often fabricated from calcium orthosilicate.

Description

The stoichiometry of the hydrate in cement paste is variable and the state of the chemically and physically bound water in its structure is not clear. Thus, calcium silicate can be prepared by calcining the oxide with silica, SiO2, at an elevated temperature: CaO + SiO2+ hea?CaSiO3

Chemical Properties

white or cream powder

Chemical Properties

Calcium silicate occurs as a crystalline or amorphous white or offwhite material, and often exists in different hydrate forms.

Uses

Constituent (produced in situ) of lime glass, portland cement; reinforcing filler in elastomers and plastics; absorbent for liquids, gases, vapors; as anti-caking agent, suspension agent, pigment and pigment extender; binder for refractory material; in chromatography; in road construction.

Uses

Calcium Silicate is an anticaking agent that exists in different forms, which are insoluble in water. it is used in salt to enhance flowability under extremely high humidity conditions. it is also used in baking powder and fabricated chips to absorb water or other liquids.

Production Methods

When used in oral formulations, calcium silicate is practically nontoxic. Inhalation of the dust particles may cause respiratory tract irritation.

Hazard

Irritating dust. Use in foods restricted to 5% in baking powder, 2% in table salt. Upper res- piratory tract irritant. Questionable carcinogen.

Pharmaceutical Applications

Calcium silicate is used as a filler aid for oral pharmaceuticals. It has also been used in pharmaceutical preparations as an antacid.
The main applications of calcium silicate relate to its anticaking properties, and it has therefore been used in dusting powders and a range of different cosmetic products (e.g. face powders, eye shadow).

Safety Profile

A nuisance dust

Safety

GRAS listed. Included in the FDA Inactive Ingredients Database (oral dosage forms). Included in nonparenteral (oral, orodispersible, effervescent and enteric-coated tablets) formulations licensed in the UK.

storage

Calcium silicate is chemically stable and nonflammable, but it should be protected from moisture. Store in airtight containers in a cool, dry place.

Incompatibilities

Calcium silicate is a naturally occurring mineral, but for commercial applications it is usually prepared from lime and diatomaceous earth under carefully controlled conditions.

Regulatory Status

Calcium diorthosilicate; calcium trisilicate.
