Calcium - Wikipedia

On a large scale, it is prepared by passing carbon dioxide gas through calcium hydroxide (slaked lime). However, if carbon dioxide is passed in excess, it forms the soluble calcium hydrogen-carbonate. Ca (OH)2 + CO2→ CaCO3 + H2O Properties of CaCO3 It is a fluffy powder. It decomposes to give carbon dioxide when heated up to 1200K.

Calcium (Ca) - Chemical properties, Health and Environmental effects

Calcium is a very reactive metal and coines readily with oxygen to form oxides. Loss of calcium leads to very soft grids that are difficult to handle and process, excessive drossing, and suspended oxides in the alloy. The suspended oxides produce casting defects and subsequently early grid failure in corrosion.
