Hafnium phofo
Tlhaloso ea Sehlahisoa
Hafnium phofo ke tšepe e tšoeu ea silevera, ho ea ka thepa ea 'mele, phofo ea hafnium e na le ntlha e phahameng ea ho qhibiliha le ntlha e phahameng ea ho belisa, ntlha ea eona ea ho qhibiliha ke 2545 ° C, ntlha e belang ke 3876 ° C. E boetse e na le mocheso o phahameng oa mocheso. le resistivity e phahameng, kahoo hangata e sebelisoa ha ho etsoa li-superalloys le likarolo tsa elektronike.Mabapi le thepa ea lik'hemik'hale, phofo ea hafnium e bonolo ho itšoara ka likarolo tse seng tsa tšepe tse kang oksijene le naetrojene ho hlahisa li-oxide le nitride tse lumellanang.E boetse e etsa li-alloys tse nang le litšepe tse ngata, tse kang li-alloys tse thehiloeng hafnium.Mabapi le tšebeliso le bohlokoa, phofo ea hafnium ke thepa ea bohlokoa haholo, e sebelisoang haholo sebakeng sa lifofane, sesole, lisebelisoa tsa elektronike le tse ling.Mohlala, e entsoe ka tungsten, rhenium le litšepe tse ling hore e be li-alloys tse thehiloeng ho hafnium tse matla haholo, tse hanyetsanang le mocheso o phahameng bakeng sa ho etsa lienjineri tsa lifofane le lienjine tsa rokete.Ho feta moo, phofo ea hafnium e ka boela ea sebelisoa ho etsa lisebelisoa tsa elektronike, tse kang capacitor, resistors, joalo-joalo.

Hafnium Hf phofo e sebelisoa haholo bakeng sa:
1. Ho sebelisoa ka tloaelo ho X-ray cathode le tungsten terata tlhahiso;
2. Hafnium e hloekileng e na le melemo ea polasetiki, ho sebetsa habonolo le ho hanyetsa mocheso o phahameng oa mocheso, 'me ke thepa ea bohlokoa indastering ea matla a athomo;
3. Hafnium e na le karolo e kholo ea mocheso oa li-neutron tse tšoarang mocheso, e leng se etsang hore e be mokelikeli o motle oa neutron, o ka sebelisoang e le molamu oa ho laola le sesebelisoa se sireletsang li-reactors tsa athomo;
4. Hafnium phofo e ka sebelisoa e le propellant bakeng sa lirokete
5. Hafnium e ka sebelisoa e le getter bakeng sa mekhoa e mengata ea inflatable.Hafnium getter e ka tlosa oksijene, naetrojene le likhase tse ling tse sa hlokahaleng tse teng tsamaisong;
6. Hafnium e atisa ho sebelisoa e le tlatsetso ka oli ea hydraulic ho thibela ho senyeha ha oli ea hydraulic nakong ea ts'ebetso e kotsi haholo.Ha Hafnium e na le anti-volatility e matla, hangata e sebelisoa ho oli ea hydraulic ea indasteri le oli ea hydraulic ea bongaka;
7. Hafnium element e boetse e sebelisoa ho processor ea morao-rao ea Intel45nm;
8. Li-alloys tsa Hafnium li ka sebelisoa e le tšireletso e ka pele bakeng sa li-nozzles tsa rocket le likoloi tse kenang hape, 'me li-alloys tsa Hf-Ta li ka sebelisoa ho etsa lisebelisoa tsa lisebelisoa le lisebelisoa tsa ho hanyetsa.Hafnium e sebelisoa e le karolo ea tlatsetso ho li-alloys tse thibelang mocheso, joalo ka lialloys tsa tungsten, molybdenum le tantalum.HfC e ka sebelisoa e le kenyelletso ea carbide e entsoeng ka samente ka lebaka la boima ba eona bo phahameng le ntlha ea ho qhibiliha.
Lihlahisoa tse Amanang
Re boetse re fana ka terata ea hafnium le molamu oa hafnium, re amohelehile ho buisana!
