Yintoni i-tungsten hexioride esetyenziselwa ntoni?
Yintoni i-tungsten hexioride esetyenziselwa ntoni?
Tungsten hexifluoride yirhasi engenabubala, enetyhefu kunye nengcambu yegesi malunga ne-13 g / l, emalunga namaxesha ali-11 ukuxinana komoya kunye negesi enye. Kumzi-mveliso we-semicondcuctor, i-tungsten hexisluoride isetyenziswa ikakhulu kwi-Vapor yePhemikhali yePhemikhali (i-CVD) yokufaka idipozithi ye-tungsten. Ifilimu ye-tungsten engafakwanga inokusetyenziswa njengomgca we-uqhagamshelo wemingxunya kunye nemingxunya yoqhakamshelwano, kwaye ineempawu zokungaxhathisi esezantsi kunye nendawo ephezulu yokunyibilika. I-tungsten hexisluoride ikwasetyenziswa kwi-etching yechiza, i-plasma etching kunye nezinye iinkqubo.
Ithini igesi engenabungozi?
Irhasi engenabungozi ayinabungozi yi-argon (i-AR) enexilongo le-1.7845 g / l. UArgon yirhasi ye-Intert, engenabala kwaye engenamabala kwaye engenamabala, kwaye akasasebenzi ngokulula ngezinye izinto. Igesi ye-Argon isetyenziswa ikakhulu kukhuselo lwegesi, i-welding yemveli, ukusika intsimbi, i-laser kunye namanye amasimi.
Ngaba i-tungsten inamandla kune-titanium?
I-Tungsten kunye ne-titanium zombini zenziwe izinto zentsimbi ezinamanqaku aphezulu anyibilikayo kunye namandla. Inqaku lokunyibilika kwe-Tungsten yi-3422 ° C kunye namandla yi-500 MPA, ngelixa inyibilika ye-titanium ngo-1668 ° C kwaye amandla yi-434 MPA. Ke ngoko, i-tungsten inamandla kune-titanium.
Injani ityhefu yetyhefu?
Tungsten hexifluoride yirhasi enetyhefu kakhulu enokubangela umonakalo omkhulu emzimbeni womntu ukuba uyaphefumlelwa. I-LD50 ye-tungsten hexisluoride yi-5.6 mg / kg, oko kukuthi, ukuphefumla kwe-5.6 mg ye-tungsten hexistel ye-tungsten yobunzima bomzimba kuya kukhokelela kwi-50% yenqanaba lokufa. I-tungsten hexisluoride inokucaphukisa iphecana lokuphefumla, elibangela iimpawu ezinjengokukhohlela, ukuqina kwesifuba, kunye ne-dyspnea. Amatyala anzima anokukhokelela kwi-pulmonary ye-Edema, ukusilela kokuphefumla nokufa.
Ngaba uza kugqobhoza?
I-Tungsten ayizukuphamba. I-Tungsten yintsimbi ye-InErt engasasebenzi ngokulula ngeoksijini emoyeni. Ke ngoko, i-tungsten ayizukukhala kubushushu obuqhelekileyo.
Ngaba i-acid corrode toungsten?
I-AIDS inokukhupha ityhunga, kodwa kwinqanaba elicothayo. I-acid eqinileyo njenge-icid egxile kwi-acid kunye ne-hydrochloric acid carrode i-corrode toungten, kodwa kuthatha ixesha elide. I-Acids ebuthathaka njenge-diluturic acid kwaye i-dilute hydrochloric acid inefuthe lobuthathaka kwi-tungsten.
