How it is made
Produced by electrolysis of calcium chloride: Rathenau, Suter, Ger. Pat. 155,433 (1903): Z Elektrochem 10, 502 (1904), Goodwin, J Am Chem Soc 27, 1403 (1905), also by thermal reduction of lime with aluminum, or with silicon. Prepn of pure metal for laboratory use: Whaley, Inorg Syn 6, 18 (1960). Purification of commercial material: Marshall, Whaley, ibid 24.
Calcium is produced by high-temperature vacuum reduction with aluminum
Redistillation is used to prepare calcium with a purity of 99+%
