Applications Of Molybdenum And Its Alloy

With the development of science and technology, the application of Molybdenum in high technology and other fields has increased. We will now examine the applications of Molybdenum and its alloys.

Iron and Steel Industry

Molybdenum is an element that forms carbides and does not oxidise during steel production. It can be used alone or with other alloying elements. Molybdenum is combined with chromium, nickel, manganese and silicon to manufacture various types of stainless steel, tool steel, high‐speed steel and alloy steel.

Electrical and Electronics Industry

Molybdenum exhibits high electrical conductivity and maintains its properties at elevated temperatures, given that its thermal expansion coefficient closely corresponds to that of glass. It is frequently used for the core, lead, support rod and other components of the coiled filament in incandescent bulbs, and as a grid and anode support in electron tubes.

In addition to using pure Molybdenum in modern electronics, Mo-Re alloys are employed as structural materials for electron tubes and specialised incandescent bulbs. Moreover, Mo-50Re and TZM alloys serve as structural components for thermionic cathodes in high-performance microwave tubes and millimetre-wave tubes.

Automotive Coating

Molybdenum has a melting point of up to 2 620 °C. It exhibits high temperature and corrosion resistance and bonds strongly with steel. Therefore, it is the primary material for thermal spraying in the manufacture of automotive parts. Thermal spray materials enhance the performance of piston rings, synchronising rings, shift forks and other worn components, and are also used for repairing worn crankshafts, rollers, shafts and other mechanical parts.

High Temperature Components

Molybdenum exhibits high purity, high temperature resistance and a low vapour pressure. It is used to manufacture heating elements and structural materials for high temperature furnaces. Molybdenum demonstrates resistance to ablation in molten quartz and is employed as an electrode for excitation and melting in the glass industry, with a service life exceeding one year.

In addition to its use as an electrode, Molybdenum is applied as a high temperature structural material in glass melting, for uses such as guide grooves and tubes. The substitution of platinum with Molybdenum in the optical fibre drawing furnace reduces production costs. Furthermore, Molybdenum and its alloys are used in hot isostatic pressing, heat shields, sinter vapour painting vessels and other similar applications.

Oil Refinement

Molybdenum is employed in oil and gas pipelines. It is also used in combination with cobalt and nickel as a catalyst in petroleum refining and pre-treatment, particularly for the desulphurisation of crude oil, petrochemical products and liquefied coal. Molybdenum plays a role in the cracking and reforming of petroleum and serves as an electron donor and acceptor.
