Tungsten hexafluoride ikoreshwa iki?

Tungsten hexafluorideni gaze itagira ibara, uburozi kandi bwangirika hamwe nubucucike bwa 13 g / L, bingana ninshuro 11 ubwinshi bwumwuka hamwe nimwe muri gaze yuzuye. Mu nganda za semiconductor, tungsten hexafluoride ikoreshwa cyane muburyo bwo kubika imyuka ya chimique (CVD) kugirango ibike ibyuma bya tungsten. Filime yabitswe ya tungsten irashobora gukoreshwa nkumurongo uhuza unyuze mu mwobo no mu mwobo, kandi ufite ibiranga imbaraga nke zo kurwanya no gushonga cyane. Tungsten hexafluoride nayo ikoreshwa mubutaka bwimiti, plasma no mubindi bikorwa.

Niki gaze yuzuye idafite uburozi?

Gazi yuzuye idafite uburozi ni argon (Ar) ifite ubucucike bwa 1.7845 g / L. Argon ni gaze ya inert, idafite ibara kandi idafite impumuro nziza, kandi ntishobora kubyitwaramo neza nibindi bintu. Gazi ya Argon ikoreshwa cyane cyane mukurinda gaze, gusudira ibyuma, gukata ibyuma, laser nindi mirima.

Tungsten irakomeye kuruta titanium?

Tungsten na titanium byombi ni ibintu byuma bifite imbaraga zo gushonga hamwe nimbaraga. Ingingo yo gushonga ya tungsten ni 3422 ° C n'imbaraga ni 500 MPa, mugihe aho gushonga kwa titanium ari 1668 ° C n'imbaraga ni 434 MPa. Kubwibyo, tungsten irakomeye kuruta titanium.

Nigute uburozi bwa tungsten hexafluoride?

Tungsten hexafluorideni gaze yuburozi cyane ishobora kwangiza cyane umubiri wumuntu iyo ihumeka. LD50 ya tungsten hexafluoride ni 5.6 mg / kg, ni ukuvuga guhumeka mg 5,6 za tungsten hexafluoride kuri kilo yuburemere bwumubiri bizavamo 50%. Tungsten hexafluoride irashobora kurakaza inzira z'ubuhumekero, bigatera ibimenyetso nko gukorora, gukomera mu gatuza, na dyspnea. Indwara zikomeye zirashobora gutera indwara yo mu bihaha, kunanirwa guhumeka ndetse no gupfa.

Tungsten ingese?

Tungsten ntishobora kubora. Tungsten ni icyuma cya inert kidakora byoroshye na ogisijeni mu kirere. Kubwibyo, tungsten ntishobora kubora kubushyuhe busanzwe.

Acide irashobora kwangirika tungsten?

Acide irashobora kwangiza tungsten, ariko ku gipimo gito. Acide ikomeye nka acide sulfurike yibanze hamwe na aside hydrochloric aside irashobora kwangiza tungsten, ariko bifata igihe kirekire. Acide nkeya nka acide sulfurike na acide hydrochloric aside igira ingaruka mbi kuri tungsten.
