Yini i-tungsten hexafluoride esetshenziselwa?
Yini i-tungsten hexafluoride esetshenziselwa?
Tungsten hexafluoride igesi engenamibala, enobuthi futhi esolisayo enobude be-13 G / L, okucishe kube izikhathi eziyi-11 ubukhulu bomoya kanye nelinye lamagesi anezinkinga. Embonini ye-semiconductor, i-tungsten hexafluoride isetshenziswa kakhulu kwinqubo yamakhemikhali ye-VAPOR Deposition (CVD) ukufaka i-Tungsten Metal. Ifilimu le-tungsten elifakiwe lingasetshenziswa njengomugqa wokuxhumana phakathi kwezimbobo kanye nezimbobo zokuxhumana, futhi inezimpawu zokumelana okuphansi nendawo ephezulu yokuncibilika. I-Tungsten Hexafluoride nayo isetshenziswa kumakhemikhali etching, i-plasma etching kanye nezinye izinqubo.
Yiliphi igesi engenalo ubuthi?
Igesi e-densest engeyona ubuthi yi-argon (AR) ene-density ka-1.7845 g / l. I-Argon ingugesi we-inert, engenamibala nophunga, futhi ayisabeli kalula nezinye izinto. Igesi ye-Argon isetshenziswa kakhulu ekuvikelweni kwegesi, ukufudumala kwensimbi, ukusika insimbi, i-laser kanye nezinye izinkambu.
Ingabe uTungsten unamandla kune-titanium?
UTungstern neTitanium zombili izinto zensimbi enamaphoyinti aphezulu ancibilikayo namandla. Iphoyinti elincibilikayo leTungsten lingu-3422 ° C futhi amandla angama-500 MPA, ngenkathi iphuzu lokuncibilika le-titanium lingu-1668 ° C futhi amandla angama-434 MPA. Ngakho-ke, uTungsten unamandla kune-titanium.
I-Fungsten Hexafluoride Kanjani?
Tungsten hexafluoride igesi enobuthi kakhulu engadala ukulimala okukhulu emzimbeni womuntu uma inhaniwe. I-LD50 ye-tungsten hexafluoride ingu-5.6 mg / kg, okungukuthi, ukuphefumula kuka-5.6 mg we-tungsten hexafluoride ngekhilogremu yensimbi yomzimba kuzoholela ekufeni kuka-50%. UTungsten Hexafluoride angacasula ipheshana lokuphefumula, abangele izimpawu ezinjengokukhwehlela, ukuqina kwesifuba kanye ne-dyspnea. Amacala amakhulu angaholela e-Pulmonary Edema, ukwehluleka kokuphefumula kanye nokufa.
Ngabe ukugqwala kwe-tungsten?
UTungsten ngeke ukugqwala. UTungsten uyinsimbi enobuntu obungasabeli kalula ngo-oxygen emoyeni. Ngakho-ke, uTungsten ngeke agqwala ekushiseni okujwayelekile.
Ngabe i-acid corrode tungsten?
Ama-acid angalungisa ama-tungsten, kodwa ngesilinganiso esikahle. Ama-acid anamandla anjenge-sulfuric acid egxilile kanye ne-hydrochloric acid egxilile angalungisa amaTurngs, kepha kuthatha isikhathi eside. Ama-acid abuthakathaka afana ne-dilute sulfuric acid kanye ne-dilute hydrochloric acid inomphumela obuthakathaka obuthakathaka eTungsten.
