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.
