Crucibles, details of technological equipment, for example, thermocouple covers of stirrers, etc., made of high-density metal (99.3...99.9%) of special purity
(impurity content <10-3 % weight)-3 % ваг.)
possess high stability at very high temperatures. in aggressive media (melts of alkali, alkaline-earth and other metals and compounds).
The crucibles are successfully used for growing single crystals of semiconductors (АIIIBV etc.), oxides (ruby, leucosapphire), for melting metals and for other high-temperature technological processes.
The long service life of crucibles, their high performance make the fundamentally new design and technological solutions a reality.
It is possible::
- production of crucibles made of W and W-Re alloys, as well as composite crucibles (graphite or Mo crucibles coated with W, Re, W-Re, Ta;
сrucible dimensions:
діаметр до 120 мм
вишина до 240 мм
товщина стінок до 10 мм
- plating of crucibles from other high-temperature materials, including oxidizing, carbide, nitride, etc;
- production of elements of technological equipment;
- manufacturing of parts from W, Re and W-Re of complex configuration.
