Calcium | Element, Properties, Uses, Compounds

Feb 12, 2021· Calcium superoxide is formed by the reaction of metal peroxide with 30 percent hydrogen peroxide. The oxides react with water to form hydroxides and the basic properties of Group-2 hydroxides increase from beryllium to barium. Halides. All the crystalline halides of calcium are ionic in nature with a high melting point.

Rare-earth element - Preparation of the metals | Britannica

The metal is then heated in a high vacuum in a tantalum crucible to above its melting point to evaporate the excess calcium. At that point R may be further purified by sublimation or distillation. This procedure is used to prepare all the rare earths except samarium, europium, thulium, and ytterbium.
