Calcium is a silvery white metal. The surface of calcium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium. Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium
Calcium metal is commonly employed in the high quality and special types of steelmaking. The calcium treatment can control shape, distribution and fluidity of the modified inclusions. The following are beneficial effects of using calcium metal in secondary refining. …
