| Calcium silicate Usage And Synthesis |
| Description | Calcium Silicate is a hydrous or anhydrous silicate with varying proportions of calcium oxideand silica. many different calcium silicates occur in nature in mineral form (e.g.,wollastonite, afwillite, grammite). 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+ heat→CaSiO3. 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. |
| Chemical Properties | Calcium silicate occurs as a crystalline or amorphous white or off white material, and often exists in different hydrate forms. It consists of different ratios of CaO and SiO4, including tricalcium silicate (3CaO.SiO2) and dicalcium silicate Ca2SiO4. It is insoluble in water and forms a gel with inorganic acids. The pH of 5% suspension is 8.4~10.2. |
| 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 | Calcium silicate is made in various ways by reacting siliceous material (such as diatomaceous earth) and calcium compounds (such as calcium hydroxide (Ca (OH) 2).The refinement of wollastonite ore into high-grade wollastonite was originally done by manual selection at many mines. This process is now performed by screening and magnetic separators, sometimes in combination with flotation and vacuum filtration. Grinding and milling operations can produce variable mesh powders or aggregates. |
| Application | 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). It is also used as anticaking agent in table salt, foods, pharmaceuticals, and agricultural pesticides; replacement for asbestos in thermal insulation; 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. |
| Preparation | Calcium silicate is a naturally occurring mineral, but for commercial applications it is usually prepared from lime and diatomaceous earth under carefully controlled conditions. |
