Opis ogólny

Molybdenum(VI) oxide, also known as molybdenum trioxide, is a compound of molybdenum and oxygen with the approximate chemical formula of MoO3. 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. Molybdenum(VI) oxide has a high melting point of 2,620 °C. Chemically, molybdenum(VI) oxide is a strong oxidizing agent and has a high work function. Consequently, it is used as a catalyst in chemical reactions and as a starting material to produce other molybdenum compounds. In addition, it is added to pigments, glasses, lubricants, and plastics.

Zastosowanie

Precursor to LAMOX fast ion conductors and superconductors.
Used in the solid state synthesis of a remarkable ternary, reduced molybdenum oxide, Pr4Mo9O18, whose structure contains previously unknown Mo7, Mo13 and Mo19 clusters. The new cluster product is a small band gap semiconductor.
