Hafnium Dioxide Precursor: Hoʻohana mua ʻia ʻo Hafnium tetrachloride ma ke ʻano he precursor e hana i ka hafnium dioxide (HfO2), kahi mea me nā waiwai dielectric maikaʻi loa. Hoʻohana nui ʻia ka HfO2 i nā noi dielectric kiʻekiʻe no nā transistors a me nā capacitors i ka ʻoihana semiconductor. He mea nui ka HfCl4 i ka hana ʻana i nā mea uila holomua ma muli o kona hiki ke hana i nā kiʻiʻoniʻoni lahilahi o ka hafnium dioxide.
ʻO ka hoʻoheheʻe ʻia ʻana o ke kino: Hiki ke hoʻohana ʻia ʻo Hafnium tetrachloride ma ke ʻano he catalyst no nā ʻano like ʻole synthesis reactions, ʻoi aku ka polymerization olefin. ʻO kāna mau waiwai Lewis acid ke kōkua i ka hoʻokumu ʻana i nā intermediates ikaika, a laila e hoʻomaikaʻi ai i ka pono o nā hopena kemika. He mea waiwai kēia noi i ka hana ʻana i nā polymers a me nā mea hoʻohui ʻē aʻe i ka ʻoihana kemika.
Hoʻohana Nukelea: Ma muli o kona kiʻekiʻe neutron absorption cross section, hafnium tetrachloride i hoʻohana nui ʻia i nā noi nuklea, ʻoi aku hoʻi i nā koʻokoʻo mana o nā reactors nuklea. Hiki i ka Hafnium ke komo pono i nā neutrons, no laila he mea kūpono ia no ka hoʻoponopono ʻana i ke kaʻina hana fission, e kōkua ana i ka hoʻomaikaʻi ʻana i ka palekana a me ka pono o ka hana nuklea.
Hoʻomoe kiʻiʻoniʻoni lahilahi: Hoʻohana ʻia ʻo Hafnium tetrachloride i nā kaʻina hoʻoheheʻe kemika (CVD) e hana i nā kiʻiʻoniʻoni lahilahi o nā mea hafnium-based. Pono kēia mau kiʻiʻoniʻoni i nā ʻano noi like ʻole, me ka microelectronics, optics, a me nā pale pale. ʻO ka hiki ke waiho i nā kiʻiʻoniʻoni kiʻekiʻe i ka HfCl4 i mea waiwai i nā kaʻina hana holomua.
