Description

General description

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.

Application

Used in the solid state synthesis of a remarkable ternary, reduced molybdenum oxide, Pr₄Mo₉O₁₈, whose structure contains previously unknown Mo₇, Mo₁₃and Mo₁₉ clusters. The new cluster product is a small band gap semiconductor.

Precursor to LAMOX fast ion conductors and superconductors.
