ARTICLES MADE OF TUNGSTEN, RHENIUM AND THEIR ALLOYS

 

Crucibles, components of process equipment, e.g., thermocouple casing, mixers, etc., made of a high-density (99,3...99,9 %) metal cf high purity (<10-3 wt.% impurities) show a high resistance at very high temperatures in aggressive media, e.g., melts of alkali, alkali-earth metals, etc., and their compounds.

The proposed crucibles are advantageously used to grow single crystals of semiconductors (A3B5, etc.), oxides (ruby, leucosapphires), to melt metals and to carry out other high-temperature technological processes.

Excellent performance characteristics and a long service life of crucibles will make feasible radically new design and technological advances.

 

 

 

 

 

 

 

We take orders:

 

to produce W and W-Re crucibles, and also composite crucibles (e.g., graphite - or Mo-crucibles with W, Re, W-Re, Ta coating of different thicknesses).

 

 

The crucible dimentions can be:

diameter up to 120 mm

height up to 240 mm

wall thickness up to 10 mm
