Percy Gilchrist

Born 27 Dec 1851; died 16 Dec 1935 at age 83.Percy Carlyle Gilchrist was an English metallurgist who is known for the Thomas-Gilchrist process (1876-77) he developedwhile assistant to his cousin, Sidney Gilchrist Thomas. This process manufactured low-phosphorus steel known as Thomas steel, in Bessemer converters and was adopted throughout Europe where iron ore has phosphorus impurities. The key feature of this process is the use of lime (calcined dolomite) to line the converter instead of acidic silica. The lime is a base and it captures acidic phosphorus oxides produced when air is blown through the molten iron. The phosphorous content, which otherwise makes steel brittle, was reduced to about 0.04%. Additionally, the cinder waste product of the steelmaking could be used as valuable artificial fertilizer.«
