Calcium - Wikipedia

2019-5-16 · Calcium metal is found in some drain cleaners, where it functions to generate heat and calcium hydroxide that saponifies the fats and liquefies the proteins (for example, those in hair) that block drains. Besides metallurgy, the reactivity of calcium is exploited to remove nitrogen from high-purity argon gas and as a getter for oxygen and nitrogen.

Electrolytic Production of Calcium Metal

The resulting calcium-tin alloy served as the anode for the electrorefming cell, which employed a CaC~-CaF2 fused salt as the electrolyte. Calcium metal was electrorefmed at 8500 C with a current efficiency of 85 pct based on calcium metal recovered. The calcium metal analyzed 99.2 pct, which is purer than commercially produced calcium.
