Izingcezu ze-Molybdenum Disilicide
I-Molybdenum Disilicide (MoSi2) iyinto ethembisayo yekhandidethi yezinhlelo zokusebenza zesakhiwo sokushisa okuphezulu. Iyindawo ephezulu yokuncibilika (2030 °C) enokumelana okuhle kakhulu ne-oxidation kanye nokuminyana okumaphakathi (6.24 g/cm3). Ayincibiliki kuma-asidi amaningi, kodwa incibilika ku-nitric acid ne-hydrofluoric acid. Irediya yezinhlobo ezimbili zama-athomu awahlukene kakhulu, amandla e-electronegativity asondele kakhulu, futhi anezakhiwo ezifana nezezinsimbi nezitsha zobumba. I-Molybdenum Disilicide iyaqhuba futhi ingakha ungqimba lwe-passivation lwe-silicon dioxide endaweni emazingeni okushisa aphezulu ukuvimbela ukukhuphuka kwe-oxidation. Isetshenziswa emkhakheni wezinto zokushisa eziphakeme zokushisa eziphikisana ne-oxidation, izakhi zokushisa zikagesi, amafilimu ahlanganisiwe e-electrode, izinto zokwakha, izinto eziyinhlanganisela, izinto ezingagqoki, izinto zokuxhuma ze-ceramic zesakhiwo nezinye izinkambu.
I-Molybdenum Disilicide ingasetshenziswa ezimbonini eziningi ezihlukene: 1) Imboni yamandla namakhemikhali: I-MoSi2 isetshenziswa njengento yokushisa kagesi, isishintshi sokushisa esiphezulu sedivayisi ye-athomu ye-athomu, isishisi segesi, ukushisa okuphezulu kwe-thermocouple kanye neshubhu layo lokuvikela, i-crucible yomkhumbi wokuncibilika. (esetshenziselwa ukuncibilikisa i-sodium, i-lithium, umthofu, i-bismuth, ithini nezinye izinsimbi). 2) Imboni ye-Microelectronics: I-MoSi2 kanye nezinye i-Silicides zensimbi eziphikisayo i-Ti5Si3, i-WSi2, i-TaSi2, njll. zingamakhandidethi abalulekile amasango esekethe ahlanganisiwe amakhulu nokuxhumana. 3) Imboni ye-Aerospace: I-MoSi2 njengento enamathela emazingeni okushisa aphezulu e-anti-oxidation, ikakhulukazi njengempahla yezingxenye zenjini yomoya, njengama-blades, ama-impeller, amagumbi avuthayo, imibhobho kanye nemishini yokuvala, iye yenziwa kabanzi futhi ijulile Ucwaningo nokusebenzisa. . 4) Imboni yezimoto: I-Molybdenum Disilicide MoSi2 isetshenziswa kuma-rotor e-automobile turbocharger, imizimba yamavalvu, ama-spark plug kanye nezingxenye zenjini.
I-Rich Special Materials igxile Ekwenziweni Kwethagethi Ye-Sputtering futhi ingakhiqiza izingcezu ze-Molybdenum Disilicide ngokuya ngokucaciswa kweKhasimende. Ukuze uthole ukwaziswa okwengeziwe, sicela usithinte.
