tungsten molybdenum developed

Molybdenum History + General Information Midwest Tungsten Tests designed to evaluate molybdenums ability to replace tungsten as an additive in tool steel were unsuccessful, primarily because of sulfur and phosphorus impurities in the molybdenum. In 1894, grey molybdenum oxide was produced in an electric furnace. The oxide contained 9% carbon, which made the compound hard enough to scratch glass.
