Preparation of tungsten crucibles starting from tungsten fluoride
The study results are presented on technology development for forming of cylindrical tungsten crucibles starting from tungsten fluoride by reduction WF₆ with hydrogen in horizontal flow-type reaction under reduced pressure. It has been shown, that one way to nonporous with smooth outer surface, heig...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The study results are presented on technology development for forming of cylindrical tungsten crucibles starting from tungsten fluoride by reduction WF₆ with hydrogen in horizontal flow-type reaction under reduced pressure. It has been shown, that one way to nonporous with smooth outer surface, heigh surface purity and high strength consist in the deposition process realization in diffusion area at 550°C and the partial pressures ratio in the gas mixture PH₂/PWF₆ = 10/1 |
