Description
Calcium silicate, also known as calcium orthosilicate, is a white powder derived from diatomaceous earth and limestone. It is obtained by reacting calcium oxide and silica in various ratios. Calcium silicate possesses properties such as high physical water absorption and low bulk density. Due to these special physical characteristics calcium silicate has several applications in the construction sector. It is also used as a food additive in the food processing industry.
Description
Calcium hydroxide is a product derived from lime. Lime has two product forms: quick lime and hydrated lime. Quick lime is also known as carbon oxide and is solid, white and crystalline compound at the room temperature. Hydrated lime has various names such as calcium hydroxide, calcium hydrate, slaked lime, caustic lime, pickling lime and many others. It is a soft, white, powdery material with a bitter taste. It is insoluble in ethanol and slightly soluble in water and glycerol, forming a medium strong base which is known to react violently with acids, attacking many metals in the presence of water.
Description
Calcium carbide, CaC2 when pure, is transparent and colorless, with a specific gravity of 2.22 at 180oC. Commercial calcium carbide is the main source of acetylene, and acetylene is used principally in the synthesis of a series of organic chemicals, resins, and plastics and in oxyacetylene welding and cutting of metals. The main raw materials required for the manufacture of the product are limestone containing at least 98 per cent of calcium carbide, charcoal and petroleum coke. 
Description
Butane is a hydrocarbon of the alkane family with four carbon atoms attached to it. Butanes may refer to either to either of two structural isomers, n-butane (normal butane) or isobutene or to a mixture of these two isomers. Butane is a colorless, flammable and easily liquefied gas. Butane is heavier than the air with a density of approximately 575 kg per cubic meters at 15 degree Celsius. The boiling point of butane is approximately -1 degree Celsius whereas, the flash point of butane is approximately -40 degree Celsius.
