Molybdenum Crucible


Edgetech industries LLC provides molybdenum crucible manufactured by two processes. One is sintered crucible, its density is 9.8 ~ 10 g/cc, by which way crucible is sintered directly after molding. The other one is forging, density for forged crucible can reach 10.2g/cc. Small crucibles are made by forged rods & ingots.

Mo-La alloy (Lanthanum oxide doped molybdenum) is also used to make high temperature crucible, Mo-La alloy crucible can tolerate higher temperature (~200℃+) than pure Moly crucible .

Application for Moly crucibles:
Moly crucible is mainly used in metallurgy industry and mechanism process industry, and molybdenum is an indispensability material in rare earth smelting industry. Moly crucibles are more frequently used in crystallized materials, and other burgeoning high technology industry.

Specification for Moly crucible:
Our company can produce various molybdenum crucibles, such as round crucible, tapered crucible, ellipse crucible and bottomless crucible, rectangular crucible, square crucible. Crucibles can be produced according to drawings.

About Molybdenum

Molybdenum is a refractory metal with symbol Mo and the atomic number 42. It’s an outstanding material that can meet the most exacting requirements due to the unique mechanical and chemical properties. Molybdenum possesses a very high melting point, a low coefficient of thermal expansion and a high level of thermal conductivity, it is employed in many different industries.

Molybdenum is used for its extremely high melting point and relative flexibility. Molybdenum has a melting point of 2,623 °C. Molybdenum has a high elastic modulus, and only tungsten and tantalum have higher melting points. Typical applications for Moly are crucibles, evaporation boats, propulsion components, x-ray tube, lighting industry, glass melting electrodes, high temperature furnaces, sputtering targets, heat sinks, heating elements, electrodes, stirrers, orifice plates, support members, mandrels, shields, sintering trays, filaments, furnace windings, thermocouple sheathes, nose cones, nozzles, jet tabs, contacts, brazing fixtures, boring bars, tools, heat radiation shields, cathodes, and aircraft and missile parts and nuclear energy applications where high temperature resistance is crucial.
