Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7%,[1] along with silica and other dross, which makes it brittle and not useful directly as a material except for limited applications.[2]
