Isicelo

I-Hafnium Dioxide Precursor: I-Hafnium tetrachloride isetshenziswa ngokuyinhloko njengesandulela ukukhiqiza i-hafnium dioxide (HfO2), into enezinto ezinhle kakhulu ze-dielectric. I-HfO2 isetshenziswa kabanzi kuzicelo ze-dielectric eziphezulu ze-k zama-transistors nama-capacitor embonini ye-semiconductor. I-HfCl4 ibalulekile ekwenziweni kwezinto ezithuthukisiwe zikagesi ngenxa yekhono layo lokwenza amafilimu amancanyana e-hafnium dioxide.
I-Organic synthesis catalyst: I-Hafnium tetrachloride ingasetshenziswa njenge-catalyst ye-organic synthesis reactions, ikakhulukazi i-olefin polymerization. Izakhiwo zayo ze-Lewis acid zisiza ukwakha i-intermediate esebenzayo, ngaleyo ndlela ithuthukise ukusebenza kahle kokusabela kwamakhemikhali. Lolu hlelo lokusebenza lubalulekile ekukhiqizeni ama-polymers nezinye izinhlanganisela eziphilayo embonini yamakhemikhali.
Uhlelo Lwenuzi: Ngenxa yesigaba sayo esiphambanayo sokumuncwa kwe-neutron ephezulu, i-hafnium tetrachloride isetshenziswa kakhulu ekufakweni kwezikhali zenuzi, ikakhulukazi ekulawuleni izinti zeziphehli zenuzi. I-Hafnium ikwazi ukumunca ama-neutron ngempumelelo, ngakho-ke iyimpahla efanelekile yokulawula inqubo yokuqhekeka, esiza ukuthuthukisa ukuphepha nokusebenza kahle kokukhiqizwa kwamandla enuzi.
Ukubekwa Kwefilimu Encane: I-Hafnium tetrachloride isetshenziswa ezinqubweni ze-chemical vapor deposition (CVD) ukwakha amafilimu amancanyana wezinto ezisekelwe ku-hafnium. Lawa mafilimu abalulekile ekusetshenzisweni okuhlukahlukene, okuhlanganisa i-microelectronics, optics, nezingubo zokuzivikela. Amandla okufaka iyunifomu, amafilimu ekhwalithi ephezulu enza i-HfCl4 ibaluleke ezinqubweni zokukhiqiza ezithuthukile.
