Ukusetyenziswa kweeMveliso
Ukusetyenziswa kweHafnium kulinganiselwe ngenxa yobuninzi obuphantsi. Olona setyenziso luphambili lwe-hafnium kushishino lwenyukliya, apho isetyenziswa kwiintonga zamafutha ukulawula ukuqhekeka ngenxa yecandelo layo eliphezulu lokufunxa ineutron. Ngokufana ne-zirconium, i-hafnium idityaniswe ne-niobium kunye ne-carbide ukuvelisa izixhobo ezinqanda ukushisa okuphezulu kwi-furnaces kunye ne-jet components kunye nabasiki be-plasma. Ukongeza, i-hafnium oxide iya isetyenziselwa ukunyusa okanye ukubuyisela i-silicone oxide esekelwe kwi-microprocessor chips kwizicelo ezithile kunye nakwii-cathodes kunye ne-capacitors (Field et al., 2011). IHafnium inobudlelwane obukhulu bokufunxa iineutron ezicothayo. Olu phawu, kunye namandla ayo kunye nokuxhathisa umhlwa, luyenza yongamele i-cadmium, ekwasetyenziselwa ukwenza iirodi zokulawula izixhobo zenyukliya. Oku kusetyenziswa kubaluleke kakhulu kuhlobo lwezixhobo zenyukliya ezisetyenziswa kwiinkwili. Ngokususa iirodi zolawulo ngaphakathi nangaphandle kwisixhobo senyukliya, i-fission chain reaction inokulawulwa njengoko i-neutron ifunxwa kwisinyithi seentonga. Imbuyekezo kwiintonga zolawulo lwe-hafnium ziindleko zabo: ixabisa malunga nesigidi seerandi kwishumi elinesibini leentonga ukuze zisetyenziswe kwisixhobo esinye senyukliya. ioksijini okanye initrogen kumbhobho, ngaloo ndlela ukwandisa ubomi betyhubhu ye-vacuum. Iimpawu ze-Hafnium zikwayenza ilungele imicu kwiibhalbhu zokukhanya kwaye, xa ixutywe nezinyithi ezinqabileyo zomhlaba, njengentsimbi "ehlwahlwazayo" ye-misch. I-Hafnium iphinda isetyenziswe kwindawo encinci njenge-alloying agent kwezinye iintsimbi ezininzi, kubandakanya intsimbi, i-titanium, kunye ne-niobium. Kufunyenwe kwimigodi kunye nokucocwa kwesinyithi; isetyenziswa kwiintonga zolawulo kwizixhobo zenyukliya nasekuveliseni imicu yebhalbhu yokukhanya; ifunyenwe kuzo zonke i-zirconium ezinezimbiwa.
Ukupakishwa kunye noGcino
Ukupakisha:
Ipakishwe kwingxowa ephothiweyo yeplastiki engangenwa ngamanzi, 25kg ngengxowa nganye okanye ngokweemfuno zakho.
Phawula: Ukwakhiwa kweekhemikhali kunye nobukhulu bunokulungiswa ngokweemfuno zabathengi
Imiqathango yokugcina ngokukhuselekileyo, kuquka nakuphi na ukungahambelanis
Ukuthintela umlilo. Yahlulwe kwii-oxidants ezomeleleyo, iiasidi ezomeleleyo kunye neehalojeni. Gcina phantsi kwegesi engasebenziyo. Gcina kuphela kwisikhongozeli sokuqala.Ugcino: Gcina i-hafnium kwindawo engatshiyo. Yigcine ngokwahlukileyo kwi-oxidizing agents ezinamandla, iziseko eziqinileyo, i-halogens, i-phosphorus kunye nesulfure. Gcina igcinwe phantsi kwamanzi.
Ukhuseleko loKhuseleko
Izilumkiso zokuphatha ngokukhuselekileyo
AKUKHO amadangatye avulekileyo, AKUKHO iintlantsi kwaye AKUKHO msi. UNGAVUMI ukukhuhlana okanye ukothuka. Inkqubo evaliweyo, izixhobo zombane ezingaqhushumbayo kunye nezibane.
