I-Hafnium powder cas 7440-58-6

Incazelo emfushane:

I-Hafnium powder iyinsimbi empunga eyisiliva ene-metallic luster. Izakhiwo zayo zamakhemikhali zifana kakhulu ne-zirconium, futhi inokumelana nokugqwala okuhle futhi ayigqwali kalula yi-asidi evamile kanye ne-alkaline aqueous solutions; Incibilika kalula ku-hydrofluoric acid ukuze yakhe ama-fluorinated complexes

Isicelo

I-Hafnium powder isetshenziswa ezinhlobonhlobo zezicelo ngenxa yezakhiwo zayo ezihlukile. Ezinye zezinsiza eziyinhloko zihlanganisa:

1. Ukusetshenziswa Kwenuzi: I-Hafnium inengxenye enqamulayo yokumuncwa kwe-neutron ephezulu ngakho-ke isetshenziswa njengempahla yokulawula iziphehli zenuzi. Kuyasiza ukulawula inqubo ye-fission ngokumunca ama-neutron amaningi.

2. Ingxubevange: I-Hafnium ivame ukusetshenziswa kuma-alloys ukuze kwandiswe amandla awo nokumelana nokugqwala, ikakhulukazi ekusetshenzisweni kwezinga lokushisa eliphezulu. Ivamise ukungezwa kuma-superalloys asetshenziswa ku-aerospace kanye nezinjini ze-turbine.

3. I-Electronics: I-Hafnium oxide (HfO2) isetshenziswa embonini ye-semiconductor njenge-high-k dielectric material kuma-transistors, okusiza ukuthuthukisa ukusebenza kwe-microelectronic nokunciphisa ukusetshenziswa kwamandla.

4. I-Chemical Catalyst: Izinhlanganisela ze-Hafnium zingasetshenziswa njengezisusa zokusabela kwamakhemikhali okuhlukahlukene, ikakhulukazi ekukhiqizeni ama-polymers athile nezinye izinto.

5. Ucwaningo Nokuthuthukiswa: I-Hafnium powder iphinde isetshenziswe ezindaweni zocwaningo zezinhlelo zokusebenza ezihlukahlukene zokuhlola, kuhlanganise nokucwaninga kwesayensi yezinto zokwakha kanye ne-nanotechnology.

6. I-Coating: I-Hafnium ingasetshenziswa kumafilimu amancane kanye nezingubo zokuthuthukisa izakhiwo zezinto zokwakha, njengokuthuthukisa ukumelana nokugqoka nokuzinza kokushisa.

Sekukonke, i-hafnium powder ibaluleke kakhulu ngenxa yephuzu layo eliphezulu lokuncibilika, ukumelana nokugqwala, kanye nekhono lokumunca ama-neutron, okuyenza ibe yinto eguquguqukayo yezinhlelo zokusebenza ezithuthukile ezihlukahlukene.

Isitoreji

Gcina endaweni epholile nengena umoya. Hlala kude nemithombo yomlilo nokushisa. Kufanele igcinwe ngokuhlukana nama-oxidants, ama-asidi, ama-halogen, njll., futhi ugweme ukuxuba isitoreji. Yamukela izibani ezingaqhumi kanye nezindawo zokungenisa umoya. Vimbela ukusetshenziswa kwezinto eziwumshini namathuluzi ajwayele ukukhiqiza izinhlansi. Indawo yokugcina kufanele ifakwe izinto ezifanele ukuqukatha izinto ezivuzayo.

Ingabe i-Hafnium iyingozi?

I-Hafnium ngokwayo ayihlukaniswa njengento eyingozi njengezinye izinsimbi, kodwa kusenezinto ezibalulekile okufanele uziqaphele mayelana nokuphepha kwayo:

1. Ubuthi: I-Hafnium ngokuvamile ibhekwa njengenobuthi obuphansi. Nokho, ukuchayeka ku-hafnium powder (ikakhulukazi efomini lezinhlayiyana ezinhle) kungase kube yingozi empilweni, ikakhulukazi uma uhogeliwe.

2. Ingozi Yokuphefumula: Ukuhogela uthuli lwe-hafnium kungacasula uhlelo lokuphefumula. Ukuchayeka isikhathi eside noma okusezingeni eliphezulu kungase kubangele imiphumela emibi kakhulu yezempilo.

3. UKUTHINTANA KWESIKHUMBA KANYE NESO: Uthuli lwe-hafnium lungase lubangele ukucasuka uma luthinta isikhumba noma amehlo. Imishini yokuzivikela kufanele isetshenziselwe ukunciphisa le ngozi.

4. Ingozi yokuqhuma kothuli: Njengezimpushana eziningi zensimbi, i-hafnium idala ingozi yokuqhuma kothuli uma iba emoyeni futhi ukugxila kufinyelela ezingeni elithile. Ukuphatha ngendlela efanele kanye nezindlela zokugcina zibalulekile ekwehliseni le ngozi.

5. Ukusebenza Kwekhemikhali: I-Hafnium ingasabela ngama-oxidants aqinile futhi kufanele iphathwe ngokucophelela lapho kukhona izinto ezinjalo.

 

Izinyathelo eziphuthumayo

Ukuthinta isikhumba: Hlanza ngamanzi agelezayo.
Ukuthintana kwamehlo: Hlanza ngamanzi agelezayo.
Ukuhogela: Susa endaweni yesehlakalo.
Ukungenisa: Labo abaphuza ngephutha kufanele baphuze amanzi amaningi afudumele, babangele ukuhlanza, futhi bafune usizo lwezokwelapha.
