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.
