A process was developed in 1893 by Henri Moissan to produce ferrochromium in an electric furnace by the reaction of chromium oxide and carbon. In 1898 the German chemist Hans Goldschmidt produced chromium by the aluminothermic reduction of Cr 2 O 3. Other advances have included the production of chromium by aqueous electrolysis in 1954.
