CALCIUM CARBIDE is a reducing agent. May react vigorously with oxidizing materials. The powdered mixture of the acetylide and iron oxide and iron chloride burns violently upon ignition, producing molten iron. Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305°C., respectively, [Mellor, 1946, Vol. 5, 862].
Published March 2017. Calcium carbide is an inorganic compound with the following primary commercial applications: generation of acetylene, production of calcium cyanamide (a nitrogen fertilizer), and use in the iron (foundry) and steel industries as a desulfurization reagent in the production of ductile iron and steel and as a slag modifier/conditioner (reducer) in steel production.

On May 2, 1892, in Spray (now Eden), Canadian chemist Thomas L. Willson accidentally produced calcium carbide and acetylene with an electric-arc furnace. In August, Willson applied for a patent for the new process. By 1897, acetylene was competing with electricity in providing lighting, especially in rural areas and those places where gasoline was unavailable.
