Calcium is used to produce the minerals contained in bones, shells and teeth through a process called biomineralisation. Calcium phosphate (also known as hydroxyapatite) is the mineral component of bones and teeth and is a particularly good example of how organisms fabricate 'living' composite materials.alcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Uses. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
Calcium carbonate is the active ingredient in agricultural lime, and is created when calcium ions in hard water react with carbonate ions creating limescale.It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous.alcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate.
