I-Molybdenum crucibles isetshenziswa kakhulu ezimbonini ezifana ne-metallurgy, umhlaba ongavamile, i-silicon ye-monocrystalline, amakristalu okwenziwa, kanye nokucutshungulwa kwemishini. Ngenxa yezinga eliphezulu lokuncibilika le-molybdenum elifinyelela ku-2610 ℃, izinsimbi ze-molybdenum zisetshenziswa kabanzi njengeziqukathi eziyinhloko eziko ezimbonini ezifana neziko lokukhula kwekristalu elilodwa lesafire, iziko elincibilikisa ingilazi ye-quartz, indawo engavamile yokuncibilikisa umhlaba ingaphezu kweziko lokushisa okusebenzayo, njll. 2000 ℃.
I-Molybdenum crucibles inamandla amakhulu uma kuqhathaniswa, futhi amandla ayo e-matrix angaqiniswa ngezinga elithile lokucubungula okubandayo. Amanye ama-crucible anophawu nawo angaqiniswa ngokwelashwa kokushisa. Iphinde ibe nezinzuzo ezifana ne-conductivity enhle, ukuminyana okuphansi, nokucubungula okulula. I-crucible yenziwe nge-FMo-1 molybdenum powder, enomthamo womkhiqizo omkhulu kuno-9.8g/cm3 kanye nezinga lokushisa eliwu-1100 ℃.
Izakhiwo zomzimba namakhemikhali:
1. Ubumsulwa: W ≥ 99.95%;
2. Ukuminyana: ≥ 9.8g/cm3;
3. Indawo yokushisa yohlelo lokusebenza: 2400 ℃.
Ngaphezu kwalokho, ama-molybdenum crucibles asetshenziswa kakhulu emikhiqizweni eyakhiwe ehlukahlukene ngoba athintwa ubuchwepheshe bokucubungula ngesikhathi sokucubungula nokusetshenziswa. Ukwengeza, ubukhulu bazo obuncane bungaba nomthelela empilweni yabo yesevisi uma busetshenziswe ngendlela engafanele.
