molybdenum plate (Mo), or molybdenite, is a gray-metallic, silvery-coloured element with the sixth-highest melting point of any metal. It does not occur naturally as a free metal, but is found in various oxidation states in minerals.
Its high strength and ductility make it ideal for applications such as medical implants, including cardiac stents. It is also used in high-temperature vessels, such as crucibles and furnaces for rare earth metal melting.
Power electronics demand high-performance insulators that can dissipate heat reliably and maintain good electrical contacts over long periods of operation. This makes molybdenum and its alloys ideal supporting materials.
The material’s high strength and ductility also allow it to withstand extreme temperatures and chemical corrosion. It is used in energy applications, reactive chemicals, high-intensity motors and filaments, industrial molds and more.
Thermally conductive and resistant to erosion, molybdenum has a high strength-to-weight ratio and is easy to work at low temperatures. It is an excellent choice for base plates, shields and electrodes in high-temperature furnaces.
Often, molybdenum electrodes are inserted into the furnace from below through penetrations in the refractory lining. This allows them to be rejuvenated by replacing only the lengths that have eroded, thereby minimizing downtime and maintenance costs.
Because of its high resistance to oxidation, molybdenum is also a good base material for glass melting electrodes in refractory furnaces. This protects the refractory from damage, reduces downtime and improves overall productivity.
