Chii chinoshandiswa tungsten hexafluoride?

Tungsten hexafluorideigasi risina ruvara, rine muchetura uye rinoparadza rine density ingangoita 13 g/L, iyo inopeta ka11 kuwanda kwemhepo uye rimwe remagasi akaomarara. Muindasitiri yesemiconductor, tungsten hexafluoride inonyanya kushandiswa mumakemikari vapor deposition (CVD) maitiro kuisa tungsten simbi. Iyo yakaiswa tungsten firimu inogona kushandiswa seyekubatanidza mutsara we kuburikidza nemakomba uye maburi ekubata, uye ine hunhu hwekudzikira kupikisa uye yakakwirira kunyungudika. Tungsten hexafluoride inoshandiswawo mumakemikari etching, plasma etching uye mamwe maitiro.

Ndeipi gasi rinonyanya kusimba risiri muchetura?

Gasi rinonyanya kusimba risiri muchetura iargon (Ar) ine density ye1.7845 g/L. Argon igasi inert, isina ruvara uye haina kunhuwa, uye haina kuita nyore nezvimwe zvinhu. Argon gasi rinonyanya kushandiswa mukudzivirira gasi, simbi welding, simbi yekucheka, laser uye mamwe minda.

Iyo tungsten yakasimba kupfuura titanium?

Tungsten uye titanium ese ari maviri esimbi zvinhu zvine mapoinzi ekunyungudika uye simba. Nzvimbo yakanyunguduka ye tungsten i3422 ° C uye simba i500 MPa, nepo titanium inonyunguduka i1668 ° C uye simba i434 MPa. Naizvozvo, tungsten yakasimba kupfuura titanium.

Ndeipi tungsten hexafluoride ine chepfu?

Tungsten hexafluorideigasi rine muchetura zvikuru rinogona kukonzera kukuvadza kwakanyanya kumuviri wemunhu kana rikafemerwa. Iyo LD50 ye tungsten hexafluoride ndeye 5.6 mg/kg, kureva, inhalation ye5.6 mg ye tungsten hexafluoride pakirogiramu yehuremu hwemuviri huchakonzera kufa kwe50%. Tungsten hexafluoride inogona kutsamwisa nzira yekufema, zvichikonzera zviratidzo zvakadai sekukosora, kusimba kwechipfuva, uye dyspnea. Zviitiko zvakakomba zvinogona kutungamirira kupulmonary edema, kutadza kufema uye kunyange rufu.

Tungsten ichaita ngura here?

Tungsten haigoni kuita ngura. Tungsten isimbi inert isingaite nyore neokisijeni mumhepo. Nokudaro, tungsten haigoni kuita ngura pane yakajairika tembiricha.

Asidhi inogona kukanganisa tungsten here?

Acids inogona kukanganisa tungsten, asi zvishoma nezvishoma. Asidhi yakasimba yakadai seyakaomeswa sulfuric asidhi uye yakadzika hydrochloric acid inogona kukanganisa tungsten, asi zvinotora nguva yakareba. Maasidhi asina kusimba senge dilute sulfuric acid uye dilute hydrochloric acid ane kushaya simba kwekuora pa tungsten.
