Isicelo

I-Hafnium powder isetyenziswa kwizicelo ezahlukeneyo ngenxa yeempawu zayo ezizodwa. Ezinye zezona zinto zisetyenziswayo ziquka:

1. Usetyenziso lweNyukliya: IHafnium inecandelo elinqamlezileyo lokufunxa ineutron kwaye ke ngoko isetyenziswa njengesixhobo sokulawula izixhobo zenyutroni. Inceda ukulawula inkqubo ye-fission ngokufunxa ii-neutron ezingaphezulu.

2. I-alloy: I-Hafnium idla ngokusetyenziswa kwii-alloys ukunyusa amandla abo kunye nokumelana nokubola, ngokukodwa kwizicelo eziphezulu zokushisa. Ihlala yongezwa kwii-superalloys ezisetyenziswa kwi-aerospace kunye neenjini zomoya.

3. I-Electronics: I-Hafnium oxide (i-HfO2) isetyenziswe kwishishini le-semiconductor njengento ephezulu-k ye-dielectric kwi-transistors, inceda ukuphucula ukusebenza kwe-microelectronic kunye nokunciphisa ukusetyenziswa kwamandla.

4. I-Chemical Catalyst: I-Hafnium compounds ingasetyenziswa njenge-catalysts yeendlela ezahlukeneyo zeekhemikhali, ngokukodwa kwimveliso yeepolymers ezithile kunye nezinye izinto.

5. Uphando kunye noPhuhliso: I-Hafnium powder iphinda isetyenziswe kwiindawo zophando kwizicelo ezahlukeneyo zokulinga, kubandakanywa uphando kwizinto zesayensi kunye ne-nanotechnology.

6. I-Coating: I-Hafnium ingasetyenziselwa kwiifilimu ezincinci kunye neengubo zokunyusa iipropati zezinto eziphathekayo, ezifana nokuphucula ukuxhatshazwa kokugqoka kunye nokuzinza kwe-thermal.

Ngokubanzi, i-hafnium powder ixabiswa ngenxa yendawo yayo ephezulu yokunyibilika, ukuxhathisa ukubola, kunye nokukwazi ukufunxa i-neutron, iyenza ibe yimathiriyeli eguquguqukayo yosetyenziso oluphambili.

Ugcino

Gcina kwindawo epholileyo nengena umoya. Hlala kude nemithombo yomlilo nobushushu. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, i-acids, i-halogens, njl., kwaye ugweme ukuxuba ukugcinwa. Yamkela izixhobo zokukhanyisa ezingagqabhukiyo kunye neendawo zokungenisa umoya. Ukuthintela ukusetyenziswa kwezixhobo zoomatshini kunye nezixhobo ezithanda ukuvelisa iintlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezinto ezifanelekileyo eziqulathe izinto ezivuzayo.

Ngaba iHafnium iyingozi?

I-Hafnium ngokwayo ayihlelwanga njengento eyingozi njengezinye iintsimbi, kodwa kusekho izinto ezibalulekileyo ekufuneka uziqaphele malunga nokhuseleko lwayo:

1. Ubutyhefu: I-Hafnium ithathwa ngokuba inetyhefu ephantsi. Nangona kunjalo, ukuvezwa kwe-hafnium powder (ngokukodwa kwifom ye-particle fine) kunokubangela ingozi yempilo, ngakumbi ukuba i-inhaled.

2. Umngcipheko wokuphefumla: Ukuphefumla uthuli lwe-hafnium kunokucaphukisa inkqubo yokuphefumula. Ukuba sesichengeni ixesha elide okanye eliphezulu kunokubangela iziphumo ezibi zempilo.

3. ULUSU KUNYE NOQHAGAMSHELWANO LWEMEHLO: Uthuli lweHafnium lunokubangela ukucaphuka ukuba ludibana nolusu okanye amehlo. Izixhobo zokukhusela kufuneka zisetyenziswe ukunciphisa lo mngcipheko.

4. Ingozi yokudubula kothuli: Njengomgubo wesinyithi omninzi, i-hafnium ibeka umngcipheko wokudubula kothuli ukuba iphuma emoyeni kwaye ukugxila kufikelele kwinqanaba elithile. Ukuphathwa ngendlela efanelekileyo kunye neendlela zokugcina zibalulekile ekunciphiseni lo mngcipheko.

5. I-Chemical Reactivity: I-Hafnium inokusabela ngee-oxidants ezinamandla kwaye kufuneka iphathwe ngononophelo xa kukho izinto ezinjalo.

 

Amanyathelo angxamisekileyo

Ukudibanela ulusu: Sula ngamanzi abalekayo.
Ukujongana kwamehlo: Hlanza ngamanzi abalekayo.
Ukuphefumla: Susa kwindawo yesehlakalo.
Ukungenisa: Abo batya ngengozi kufuneka basele amanzi amaninzi afudumeleyo, babangele ukuhlanza, kwaye bafune unyango.
