Ohun elo

Hafnium Dioxide Precursor: Hafnium tetrachloride jẹ akọkọ ti a lo bi iṣaju lati ṣe iṣelọpọ hafnium dioxide (HfO2), ohun elo ti o ni awọn ohun-ini dielectric to dara julọ. HfO2 jẹ lilo pupọ ni awọn ohun elo dielectric giga-k fun awọn transistors ati awọn capacitors ni ile-iṣẹ semikondokito. HfCl4 ṣe pataki ni iṣelọpọ awọn ẹrọ itanna to ti ni ilọsiwaju nitori agbara rẹ lati ṣe awọn fiimu tinrin ti hafnium dioxide.
Organic kolaginni ayase: Hafnium tetrachloride le ṣee lo bi ayase fun ọpọlọpọ awọn aati iṣelọpọ Organic, paapaa olefin polymerization. Awọn ohun-ini Lewis acid rẹ ṣe iranlọwọ lati dagba awọn agbedemeji ti nṣiṣe lọwọ, nitorinaa imudarasi ṣiṣe ti awọn aati kemikali. Ohun elo yii niyelori ni iṣelọpọ awọn polima ati awọn agbo ogun Organic miiran ni ile-iṣẹ kemikali.
Ohun elo iparun: Nitori awọn oniwe-giga gbigba neutroni agbelebu apakan, hafnium tetrachloride ti wa ni o gbajumo ni lilo ninu iparun awọn ohun elo, paapa ni Iṣakoso ọpá ti iparun reactors. Hafnium le mu awọn neutroni mu ni imunadoko, nitorinaa o jẹ ohun elo ti o yẹ fun ṣiṣakoso ilana fission, eyiti o ṣe iranlọwọ lati mu aabo ati ṣiṣe ti iṣelọpọ agbara iparun.
Ifilelẹ Fiimu Tinrin: Hafnium tetrachloride ti wa ni lilo ninu awọn ilana ti o wa ni erupẹ kemikali (CVD) lati ṣe awọn fiimu tinrin ti awọn ohun elo orisun-hafnium. Awọn fiimu wọnyi jẹ pataki ni ọpọlọpọ awọn ohun elo, pẹlu microelectronics, optics, ati awọn aṣọ aabo. Agbara lati ṣafipamọ aṣọ aṣọ, awọn fiimu didara ga jẹ ki HfCl4 ṣe pataki ni awọn ilana iṣelọpọ ilọsiwaju.
