Calcium | Ca (Element) - PubChem

Calcium, a metallic element, is fifth in abundance in the earth''s crust, of which it forms more than 3%. It is an essential constituent of leaves, bones, teeth, and shells. Never found in nature uncoined, it occurs abundantly as limestone, gypsum, and fluorite. Apatite is the fluorophosphate or chlorophosphate of calcium.

Flame Retardants

2021/7/30· Flame retardants are chemicals that are applied to materials to prevent the start or slow the growth of fire. They have been used in many consumer and industrial products since the 1970s, to decrease the ability of materials to ignite. Flame retardants are often added or applied to the following products. Furnishings, such as foam, upholstery

Borosilie Glass - an overview | ScienceDirect Topics

Borosilie glass is a type of glass with the main glass-forming constituents’ silica and boron oxide. Borosilie glasses are known for having very low coefficients of thermal expansion (∼5 × 10 −6 / °C at 20 °C) making them resistant to thermal shock more so than any other common glass.
