Technical characteristics
Tungsten crucible possesses significant heat and hot resistance, high elasticity and strength, high thermal creep resistance, good heat conductivity, the lowest coefficient of thermal expansion in comparison to other metals. Tungsten crucible also possesses resistance to effect of many aggressive environments. Durable operational life and reliability of such product allow using it in manufacture of essential details.

There are a few demerits:
— difficulty of tungsten obtaining in pure state;
— high volume weight (as gold has);
— brittleness at low temperature. Tungsten crucible is not enough malleable and hard at standard temperatures. Due to its unique properties, tungsten crucible can be processed (rolled, drawn, forged) only after heating up.
Manufacture
Tungsten crucibles can be manufactured of any configuration and size of sintered, welded or drawn construction by mechanical processing. Tolerances and sizes comply with customer’s drawings. Tungsten advantages and its manufacturing method provide with durable operational life, reliability and thermal stability of crucibles. Tungsten crucible price depends on composite configurations, gauges and additional customer’s requests. Quality of products is specified by technical conditions. Volume weight is not less than 18.3 g/cm3.
Application
Tungsten crucibles are applied in metallurgy for casting, melting, distillation, refining, recovering of lutetium, yttrium, scandium and other rare-earth metals and their alloys in inert atmosphere or vacuum.
They are also used for growing of sapphires, leucosapphires, silicon monocrystals, rubies etc. Crucibles are utilized at silica melting in glass-melting furnaces, metallic film evaporation in vacuum, in furnaces with working temperature of more than 2000 °C. They are also applied in manufacture of high-quality rubies, sapphires. So that, manufacturing accurate, material purity, high density, absence of internal defects and cracks are very important things.
