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

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.
