Incazelo Yomkhiqizo

I-Hafnium powder iyinsimbi emhlophe esiliva, ngokwezakhiwo ezibonakalayo, i-hafnium powder inephuzu eliphakeme lokuncibilika kanye nendawo ephezulu yokubilisa, indawo yayo yokuncibilika i-2545 ° C, indawo yokubilisa i-3876 ° C. Ibuye ibe ne-conductivity ephezulu yokushisa. kanye nokumelana okuphezulu, ngakho-ke kuvame ukusetshenziselwa ukwenziwa kwama-superalloys kanye nezingxenye ze-elekthronikhi.Mayelana nezakhiwo zamakhemikhali, i-hafnium powder kulula ukusabela ngayo ngezinto ezingezona ezensimbi ezifana ne-oxygen ne-nitrogen ukuze kukhiqizwe ama-oxide nama-nitride ahambisanayo.Iphinde yakha ama-alloys anezinsimbi eziningi, njengama-alloys asekelwe ku-hafnium.Ngokusetshenziswa nokubaluleka, i-hafnium powder iyinto ebaluleke kakhulu, esetshenziswa kabanzi ku-aerospace, ezempi, e-electronics nakweminye imikhakha.Isibonelo, ihlanganiswe ne-tungsten, i-rhenium nezinye izinsimbi zibe ama-alloys asekelwe ku-hafnium-high-high, ukumelana nokushisa okuphezulu ukuze kwenziwe izinjini zezindiza nezinjini zamarokhethi.Ngaphezu kwalokho, i-hafnium powder ingasetshenziswa futhi ukwenza izingxenye ze-elekthronikhi, njengama-capacitors, ama-resistors, njll.

Isicelo

I-Hafnium Hf powder esetshenziselwa ikakhulukazi:

1. Okuvame ukusetshenziswa ekwakhiweni kwe-X-ray cathode kanye ne-tungsten wire;

2. I-hafnium ehlanzekile inezinzuzo zepulasitiki, ukucutshungulwa kalula kanye nokumelana nokugqwala kwezinga lokushisa eliphezulu, futhi iyinto ebalulekile embonini yamandla e-athomu;

3. I-Hafnium inengxenye enkulu yokubamba i-neutron eshisayo, eyenza ibe i-neutron absorber ekahle, engasetshenziswa njengenduku yokulawula kanye nedivayisi yokuzivikela kuma-athomu athomu;

4. I-Hafnium powder ingasetshenziswa njenge-propellant yamarokhethi

5. I-Hafnium ingasetshenziswa njenge-getter yezinhlelo eziningi ze-inflatable.I-Hafnium getter ingasusa umoya-mpilo, i-nitrogen namanye amagesi angadingekile akhona ohlelweni;

6. I-Hafnium ivame ukusetshenziswa njengesengezo kuwoyela we-hydraulic ukuvimbela ukuguquguquka kwamafutha we-hydraulic ngesikhathi sokusebenza okunobungozi obukhulu.Njengoba i-Hafnium ine-anti-volatility eqinile, ngokuvamile isetshenziselwa uwoyela wezimboni we-hydraulic namafutha we-hydraulic wezokwelapha;

7. Isici se-Hafnium siphinde sisetshenziswe ku-Intel45nm processor yakamuva;

8. Ama-alloys e-Hafnium angasetshenziswa njengokuvikela ngaphambili ama-rocket nozzles nezimoto ezitshuzayo ezingena kabusha, futhi ama-Hf-Ta alloys angasetshenziswa ukwenza izinsimbi zamathuluzi nezinto zokumelana.I-Hafnium isetshenziswa njengesengezo kuma-alloys amelana nokushisa, njengama-alloys e-tungsten, i-molybdenum, ne-tantalum.I-HfC ingasetshenziswa njengesengezo se-carbide enosimende ngenxa yokuqina kwayo okuphezulu nendawo yokuncibilika.
