Molybdenum Trays

JSC POLEMA produces sintered and deformed semi-finished products (sheets, rods), plates, electrodes for melting glass, sputtering targets, trays and other parts, using oxide-reduced molybdenum powder with purity of 99.95-99.97% as the raw material.

Thanks to the low content of interstitial impurities and metallic impurities and the small-grain texture of the material, the finished products boast outstanding plastic properties.

Some of molybdenum's important features in terms of its industrial application include its high heat resistance, electric conductivity and heat conductivity, its relatively low thermal neutron capture cross-section with a volume weight almost twice lower than that of tungsten, etc. Molybdenum's resistance to creep and stress-rupture at high temperatures in a vacuum and in protective atmosphere (argon, hydrogen) is noticeably higher than the same properties of many metals used as the base for heat-resistant materials.

As a result of molybdenum's low temperature coefficient of linear expansion and its high melting point, it ensures the dependable functionality of structures made from molybdenum that operate at high temperatures.

Molybdenum's high thermal conductivity is several times greater than that of ordinarily used heat-resistant alloys, which prevents thermal stresses during rapid heating and cooling.

Molybdenum is resistant to the effects of acids, alkalis and resistive in many molten metals and liquid glasses.
