High purity calcium metal

(1)Property

Atomic weight: 40.078

Melting point: 842 ℃

Boiling point: 1484 ℃

Density: 1.54 g/cm³

Calcium is a soft silver-white metallic element that is highly reactive chemically, and easily reacts with halogens, sulfur, nitrogen and oxygen. The rate of surface blackening decreases with metal purity in the air.
