One of these poisons is called calcium carbide. Kirk-Othmer Encyclopedia of Chemical Technology. One of the older uses of this material was in a device called the carbide lamp. The calcium carbide reagent used with the Speedy tester is a hazardous product that must be handled with care by the user and with consideration for the environment. The equipment used for the smelting of calcium carbide is similar to that employed in electric furnaces used for other forms of ferroalloys processing, where carbon is used as a reductant. Users of the Speedy must be familiar with the Speedy Moisture Test Procedure detailed in this manual. It is used as a deoxidizer i.e it helps in the removal of oxygen during the manufacturing of steel. Calcium carbide is a powerful and effective chemical reducing agent, and can also be used as a source of energy. Uses of Calcium Carbide There are various uses of it. In industry, it is widely used in the production of acetic acid and ethyl alcohol, as well as it can be used in the production of plastics, rubber, and rocket engines. Carbide lamps were still commonly used in early cars, motorcycles and bicycles as headlights, but were eventually replaced by electric lamps. The carbon needed for the synthesis of calcium acetylide is mined in an unsustainable way. In 1800, while experimenting with a voltaic cell, Humphry Davy produced the first arc light by passing an electric current between two carbon rods, which touched each other, and then drawing them apart.
