Removal of oxygen from metal oxides and solid …

19/8/2004· We claim: 1. A method for removing a substance (X) from a solid metal, a metal compound or semi-metal compound (M 1 X) by electrolysis in a fused salt of M 2 Y or a mixture of salts, which comprises conducting the electrolysis under conditions such that reaction of X rather than M 2 deposition occurs at an electrode surface, and that X dissolves in the electrolyte M 2 Y.

Calcium - Wikipedia

The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium and less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in the air to form a mixture of calcium oxide and calcium nitride.
