Davy made a paste of slaked lime [calcium oxide, slightly moistened to form calcium hydroxide] and red oxide of mercury [mercury (II) oxide]. (3) He made a depression in the paste and placed about 3.5 grams of mercury metal there to act as an electrode. Platinum was used as the counter electrode.

Magnesium calcium oxide composite - Google Patents

A product and method of manufacture are set forth. The product is used in desulfurizing steel. Magnesium is in its molten state, and with vigorous stirring, lime is added. A relatively brittle material is obtained upon cooling which can be ground to a particulate form and used in steel desulfurization. The composite is both a mixture of magnesium and lime and also includes Mg 2 Ca alloy.

Calcium - Element information, properties and uses

Lime (calcium oxide, CaO) was the useful material obtained by heating limestone and used for centuries to make plaster and mortar. Antoine Lavoisier classified it as an ‘earth’ because it seemed impossible to reduce it further, but he suspected it was the oxide of an unknown element.

Calcium Facts, Syol, Discovery, Properties, Uses

The surface of the metal remains covered by a thin layer of its oxide that prevents further attack by air (oxygen). When heated in air, it burns to produce a mixture of calcium oxide and calcium nitride. It is highly reactive towards the halogens chlorine, bromine, iodine and fluorine to form calcium dihalides [4].
