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.

Ion - Wikipedia

2019-4-26 · An ion (/ ˈ aɪ ɒ n, -ə n /) is an atom or molecule that has a net electrical charge.Since the charge of the electron (considered "negative" by convention) is equal and opposite to that of the proton (considered "positive" by convention), the net charge of an ion is non-zero due to its total nuer of electrons being unequal to its total nuer of protons.

Calcium hydride - Wikipedia

2019-5-4 · Calcium hydride is a relatively mild desiccant and, compared to molecular sieves, probably inefficient. Its use is safer than more reactive agents such as sodium metal or sodium-potassium alloy. Calcium hydride is widely used as a desiccant for basic solvents such as amines and pyridine. It is also used to dry alcohols.
