USES: Calcium metal is used in the manufacture of steel as a flux or purifier(scavenger), in the removal of bismuth from lead and in the alloying of lead for battery grid (lead acid batteries).

HANDLING: The appearance of calcium metal is silver to silver white. It is highly reactive and unstable in moist air. In air, calcium forms a "hydration" coating. Calcium can be stored in dry air (30% or less relative humidity) - this is not recommended! Calcium reacts with water liberating hydrogen which may be auto-ignitable. Finely divided calcium will auto-ignite in air. Calcium metal must be kept dry and stored in sealed metal containers under an atmosphere of argon! Storage in well ventilated area is essential. See SDS for more information.
