Ukusetshenziswa Kwemikhiqizo
Ukusetshenziswa kwe-Hafnium kukhawulelwe ngenxa yobuningi obuphansi. Ukusetshenziswa okuyinhloko kwe-hafnium kusembonini yenuzi, lapho isetshenziswa khona kuma-fuel rods ukulawula ukuqhekeka uma kubhekwa isigaba sayo esiphezulu sokumuncwa kwe-neutron. Ngokufanayo ne-zirconium, i-hafnium ixutshwa ne-niobium ne-carbide ukuze kukhiqizwe izinto ezivimbela ukushisa okuphezulu kweziko nezingxenye zejethi kanye nabasiki be-plasma. Ngaphezu kwalokho, i-hafnium oxide iya ngokuya isetshenziselwa ukukhulisa noma ukufaka esikhundleni se-silicone oxidebased microprocessor chips kwezinye izinhlelo zokusebenza kanye nama-cathodes nama-capacitor (Field et al., 2011). I-Hafnium inobudlelwane obuhle bokumunca ama-neutron ahamba kancane. Le mfanelo, kanye namandla ayo kanye nokumelana nokugqwala, iyenza iphakame kune-cadmium, ebuye isetshenziselwe ukwenza izinti zokulawula iziphehlisi zenuzi. Lokhu kusetshenziswa kubaluleke kakhulu ohlotsheni lweziphehlisi ze-nuclear ezisetshenziswa phakathi kwemikhumbi-ngwenya. Ngokuhambisa ama-rod okulawula angene futhi aphume ku-nuclearreactor, ukusabela kwe-fission chain kungalawuleka njengoba ama-neutron emuncwa ensimbi yezinduku. Ukuhlehla ezintini zokulawula i-hafnium yizindleko zazo: kubiza cishe amadola ayisigidi ngezinduku eziningana ukuze zisetshenziswe kumshini wokuphehla amandla enuzi.Kumashubhu evacuum nezinye izinhlelo zokusebenza okumelwe zikhishwe amagesi, i-hafnium isetshenziswa njenge-“getter” ukuze imunce noma yimuphi umkhondo. umoya-mpilo noma i-nitrogen ku-tube, ngaleyo ndlela andise impilo ye-vacuum tube. Izimfanelo ze-Hafnium ziyenza ifaneleke kuma-filaments kuma-light bulb futhi, uma ixutshwe nezinsimbi ezingavamile, njengensimbi "evuthayo" ye-misch. I-Hafnium iphinde isetshenziselwe into encane njenge-alloying ejenti yezinye izinsimbi ezimbalwa, okuhlanganisa i-iron, i-titanium, ne-niobium. Etholwe ezimayini nasekuhlanzweni kwensimbi; esetshenziswa ekulawuleni izinduku kuma-reactors enuzi nasekukhiqizeni imicu yamalambu okukhanya; itholakala kuwo wonke amaminerali aqukethe i-zirconium.
Iphakheji Nesitoreji
Ukupakisha:
Ipakishwe esikhwameni esilukiwe sepulasitiki esingangeni emanzini, 25kg isikhwama ngasinye noma njengezidingo zakho.
Phawula: Ukwakheka kwekhemikhali nosayizi kungenziwa ngokugcwele ngezidingo zamakhasimende
Imibandela yokugcina okuphephile, okuhlanganisa noma yikuphi ukungahambisanis
Ingashi. Ihlukaniswe nama-oxidants aqinile, ama-asidi aqinile nama-halogen. Gcina ngaphansi kwegesi ye-inert. Gcina kuphela esitsheni sokuqala.Isitoreji: Gcina i-hafnium endaweni engashi. Igcine ihlukene nama-oxidizing agents aqinile, izisekelo eziqinile, ama-halogen, i-phosphorus, nesibabule. Gcina ugcinwe ngaphansi kwamanzi.
Ukuvikela Ukuphepha
Izinyathelo zokuphepha zokuphatha okuphephile
AKUKHO amalangabi avulekile, AKUKHO izinhlansi kanye AKUKHO nokubhema. UNGAVEZI ukungqubuzana noma ukushaqeka. Isistimu evaliwe, izinto zikagesi ezingaqhumi uthuli nokukhanyisa. Vimbela ukufakwa kothuli. Ukuphatha endaweni enomoya omuhle. Gqoka izingubo ezifanele zokuzivikela. Gwema ukuthinta isikhumba namehlo. Gwema ukwakheka kothuli nama-aerosol. Sebenzisa amathuluzi angashiyi izinhlansi. Vimbela umlilo obangelwa umusi wokukhipha i-electrostatic.
