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.
1 Calcium may be used as a reducing agent in the process of metal extraction. 2  Calcium is also used in the production of some metals, as an allying agent. 3  Calcium carbonate is used to make cement and mortar and also in the glass industry.4  alcium carbonate is also added to toothpaste and mineral supplements. Calcium phosphate is used in animal feed and fertilizers. 2  Calcium hydroxide solution is used as blackboard chalk and as Plaster of Paris in its hemihydrate form. 3  Calcium gluconate is used as a food additive. 4  Calcium stearate is used to make wax crayons, cosmetics, plastics and paints.
