He aha te whakamahi tungsten hexafluoride?
Tungsten hexafluoridehe hau kore tae, paitini me te waikura me te 13 g/L te kiato, he 11 pea te roa o te kiato o te hau me tetahi o nga hau tino nui. I roto i te ahumahi semiconductor, ko te hexafluoride tungsten te nuinga e whakamahia ana i roto i te mahinga kohu matū (CVD) ki te whakatakoto i te whakarewa tungsten. Ka taea te whakamahi i te kiriata tungsten kua penapena hei raina honohono o roto i nga rua me nga kohao whakapiri, me nga ahuatanga o te aukati iti me te rewa teitei. Ka whakamahia hoki te hexafluoride tungsten i roto i te tarai matū, te tarai plasma me etahi atu tukanga.
He aha te hau tino paitini kore?
Ko te hau tino paitini kore he argon (Ar) he 1.7845 g/L te kiato. Ko te Argon he hau mokowhiti, he kore tae, he hongi, he kore e ngawari ki te mahi tahi me etahi atu matū. Ko te hau Argon te nuinga e whakamahia ana i roto i te tiaki hau, te whakarewa whakarewa, te tapahi whakarewa, te laser me etahi atu mara.
He kaha ake te tungsten i te titanium?
Ko te Tungsten me te Titanium he mea whakarewa e rua me nga tohu whakarewa teitei me te kaha. Ko te rewa o te tungsten ko 3422 ° C me te kaha ko 500 MPa, ko te rewa o te titanium ko 1668 ° C me te kaha ko 434 MPa. Na reira, he kaha ake te tungsten i te titanium.
He pehea te paitini hexafluoride tungsten?
Tungsten hexafluoridehe hau tino paitini ka pa te kino ki te tinana o te tangata mena ka ngohia. Ko te LD50 o te tungsten hexafluoride ko te 5.6 mg/kg, ara, ko te inhalation o te 5.6 mg o te tungsten hexafluoride mo ia kirokaramu o te taumaha tinana ka puta he 50% te matemate. Ka taea e te tungsten hexafluoride te whakapataritari i te rewharewha, ka puta nga tohu penei i te mare, te kopu o te uma, me te kohu. Ko nga keehi kino ka arahi ki te edema pulmonary, te ngoikore o te manawa me te mate.
Ka waikura te tungsten?
E kore e waikura te Tungsten. Ko te Tungsten he konganuku koretake e kore e tauhohe ngawari ki te hāora i te rangi. Na reira, e kore e waikura te tungsten i te pāmahana noa.
Ka taea e te waikawa te waikura te tungsten?
Ka taea e te waikawa te waikura te tungsten, engari i te tere tere. Ko nga waikawa kaha penei i te waikawa sulfuric concentrated me te waikawa hydrochloric concentrated ka taea te whakakino i te tungsten, engari he roa te waa. Ko nga waikawa ngoikore penei i te waikawa sulfuric dilute me te waikawa hauhauwai waimeha he ngoikore te paanga o te waikura ki te tungsten.
