Description and Uses
Calcium is a silvery-white metal when freshlycut, which tarnishes to a blue-gray color in air. It can alsobe found as a powder. Molecular weight=40.1; Specificgravity (H2O:1)=1.54; Boiling point=1485℃; Freezing/Melting point=849℃. Hazard Identification (based onNFPA-704 M Rating System): Health 3, Flammability 1,Reactivity 2. Reacts with water.
Calcium is largely used in the production of steel however it may also be applied to various health treatments involving the calcium-channel and anti-depressant activity. In addition it may be a necessary supplement in fracture healing of bones in mammals.
