Molybdenum carbide Chemical Properties,Usage,Production
Description
Molybdenum carbide belongs to the transition metal carbide, which is a family of interstitial compounds with metallic properties formed by carbon entering the crystal lattice of the transition metal.
Chemical Properties
Molybdenum carbide is a gray hexagonal crystal. It has the characteristics of high melting point and hardness, good thermal and mechanical stability and good corrosion resistance. The melting point is 2692°C. Insoluble in water and lye, slightly soluble in nitric acid, sulfuric acid and hydrofluoric acid.
Uses
Molybdenum carbide has a high initial catalytic activity in the benzene hydrogenation reaction. Although the catalyst gradually deactivates as the reaction progresses, its steady-state conversion frequency (TOF) is still comparable to that of noble metals Pt or Ru.
Production Methods
Polymorphism in stoichiometric and non-stoichiometric MO carbides is described. Up to 1190 ℃ the stable phase is orthohrombic α Mo-C, between 1190 ℃ and 1655℃ hexagonal βMo2C is stable. Above 1655 ℃ a non-stoichiometric MO-C phase exists, hexagonal up to 1960 ℃ and face centred cubic between 1960 and the melting point, 2580 ℃ . Heating MO and C in a solar furnace at 1600 ℃ resulted in synthesis of non-stoichiometic hexagonal MoC（1-x）in 30 minutes. It is suggested that there is a photochemical reaction.
