Hafnium Dioxide Precursor: A na-eji Hafnium tetrachloride mee ihe n'ụzọ bụ isi iji mepụta hafnium dioxide (HfO2), ihe nwere ezigbo dielectric Njirimara. A na-eji HfO2 eme ihe na ngwa dielectric dị elu maka transistor na capacitors na ụlọ ọrụ semiconductor. HfCl4 dị mkpa n'ịmepụta ngwaọrụ eletrọnịkị dị elu n'ihi ike ya imepụta ihe nkiri dị mkpa nke hafnium dioxide.
Organic njikọ na-akpali akpali: Enwere ike iji Hafnium tetrachloride mee ihe dị ka ihe na-eme ka mmeghachi omume njikọ organic dị iche iche, karịsịa olefin polymerization. Ngwongwo acid ya nke Lewis na-enyere aka etolite etiti na-arụsi ọrụ ike, si otú ahụ na-emeziwanye arụmọrụ nke mmeghachi omume kemịkal. Ngwa a bara uru na mmepụta nke polymers na ogige ndị ọzọ na-emepụta ihe na ụlọ ọrụ kemịkalụ.
Ngwa nuklia: N'ihi nnukwu neutron absorption cross section, hafnium tetrachloride bụ nke a na-ejikarị eme ihe na ngwa nuklia, karịsịa na mkpanaka njikwa nke ndị na-emepụta ngwá agha nuklia. Hafnium nwere ike ịmịnye neutron nke ọma, ya mere ọ bụ ihe kwesịrị ekwesị maka ịhazi usoro fission, nke na-enyere aka melite nchekwa na arụmọrụ nke ike nuklia.
Ntụnye ihe nkiri dị mkpa: A na-eji Hafnium tetrachloride mee ihe n'ime usoro ikuku vapor (CVD) iji mepụta ihe nkiri dị mkpa nke ihe ndị dabeere na hafnium. Ihe nkiri ndị a dị mkpa na ngwa dị iche iche, gụnyere microelectronics, optics, na mkpuchi mkpuchi. Ikike itinye otu ihe nkiri dị elu na-eme ka HfCl4 baa uru na usoro nrụpụta dị elu.
