Key characteristics

High purity:Typically,a molybdenum content of≥99.95%and extremely low impurities(such as Fe,Ni,O,C,etc.)are required to ensure stable performance.

High temperature resistance:With a melting point of up to 2620℃,it maintains its strength and shape even at high temperatures.

Low thermal expansion coefficient:suitable for precision devices in high-temperature environments.

Good thermal/electrical conductivity:superior to most metals,suitable for electronic components.

Corrosion resistance:resistant to molten metal and acid alkali corrosion(but prone to oxidation at high temperatures,requiring protective atmosphere).

Main application areas

Semiconductor industry:used for heaters,sputtering targets,boats,etc.in wafer manufacturing.

Photovoltaic industry:Back electrode materials for thin-film solar cells.

High temperature furnace components:such as heating element,insulation screen,support frame(requiring argon or hydrogen protection).

Aerospace:rocket nozzles,high-temperature structural components.

Medical equipment:X-ray tube targets,radiotherapy components.

Glass industry:electrodes and stirring rods for melting glass.

Production process

Powder metallurgy:High purity molybdenum powder is formed by isostatic pressing→high-temperature sintering→rolling→annealing.

Electron beam melting:further purification to reduce impurities.

Cold rolling/hot rolling:to produce plates of different thicknesses(commonly 0.1mm~10mm thick).

Surface treatment:acid washing,polishing,or coating(such as silicide anti-oxidation coating).
