Molybdenum crucibles
Molybdenum is characterized by high elasticity modulus, high thermal resistance and low thermal expansion coefficient, as well as high corrosion resistance in melts and alkali vapors.
Refractory nature and heat strength of molybdenum (melting point is 2620ºC) define future properties of the end product, so molybdenum crucibles proven to be very efficient in vacuum and inert gases. Moreover, electric and chemical corrosionandoxidizing resistance at high temperatures make it possible to use molybdenum in aggressive media.
A crucible is produced as follows: molding by sintering, molding by lathwork, molding by turning. Due to the fact that a crucible should not interact with materials within, only high purity molybdenum is used for production.
Depending on the purpose, the molybdenum crucibles have the most diverse shapes and sizes: cone, ellipse, with a rounded edge, without a bottom, a boat, micro and industrial crucibles, wide crucibles, tall crucibles with a reinforced edge, etc.
Depending of the purpose molybdenum crucibles have different shape and dimensions: cone, ellipsis, chamfer-edgedcrucibles, bottomless, boats, micro-crucibles, widecrucibles, highcrucibleswithreinforcededgeetc.
