Molybdenum (VI) oxide, also known as molybdenum xide, is a compound of molybdenum and oxygen with the approximate chemical formula of MoO 3. Typically, it a white or light yellow powder, although molybdenum (VI) oxide can adopt a high concentration of defects including oxygen vacancies that impart a bluish or greenish color.

The main molybdenum ore is molybdenite (molybdenum disulfide). It is processed by roasting to form molybdenum oxide, and then reducing to the metal. The main mining areas are in the USA, China, Chile and Peru. Some molybdenum is obtained as a by-product of tungsten and copper production. World production is around 200,000 tonnes per year.
