Calcium metal possesses a silvery appearance that turns grayish white on exposure to air. It has no odor and reacts with water at ambient conditions. It is soft at ordinary temperatures and is found naturally in rocks, animals, plants, soil, and volcanic dust/gases. It is an alkaline earth metal that can oxidize in air to form a protective film of oxide. It can be easily machined, extruded, or drawn into shapes. On a commercial scale, it can be produced by electrolysis of Calcium Chloride or by high-temperature vacuum reduction with Aluminum. Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity.
