Hafnium tetrachloride | HfCl4 ufa | CAS 13499-05-3 | mtengo wafakitale

Kufotokozera Kwachidule:

Hafnium tetrachloride ili ndi ntchito zofunika monga kalambulabwalo wa hafnium oxide, chothandizira kaphatikizidwe ka organic, kugwiritsa ntchito zida za nyukiliya, ndikuyika filimu yopyapyala, kuwonetsa kusinthasintha kwake komanso kufunikira kwake m'magawo osiyanasiyana aukadaulo.

Kugwiritsa ntchito

Hafnium Dioxide Precursor: Hafnium tetrachloride imagwiritsidwa ntchito ngati kalambulabwalo kuti apange hafnium dioxide (HfO2), zinthu zomwe zimakhala ndi dielectric kwambiri. HfO2 imagwiritsidwa ntchito kwambiri pamapulogalamu apamwamba kwambiri a dielectric a transistors ndi ma capacitor mumakampani opanga ma semiconductor. HfCl4 ndiyofunikira popanga zida zapamwamba zamagetsi chifukwa cha kuthekera kwake kupanga makanema owonda a hafnium dioxide.
Organic synthesis chothandizira: Hafnium tetrachloride angagwiritsidwe ntchito ngati chothandizira zosiyanasiyana organic kaphatikizidwe zimachitikira, makamaka olefin polymerization. Makhalidwe ake a Lewis acid amathandizira kupanga zoyambira zogwira ntchito, potero zimathandizira magwiridwe antchito amankhwala. Ntchitoyi ndi yofunika kwambiri popanga ma polima ndi zinthu zina zakuthupi m'makampani opanga mankhwala.
Nuclear Application: Chifukwa cha mayamwidwe ake apamwamba a nyutroni, tetrachloride ya hafnium imagwiritsidwa ntchito kwambiri popanga zida za nyukiliya, makamaka pakuwongolera ndodo za zida zanyukiliya. Hafnium imatha kuyamwa bwino ma nyutroni, chifukwa chake ndi chinthu choyenera kuwongolera njira yopatsirana, yomwe imathandizira kukonza chitetezo ndi mphamvu zamagetsi zamagetsi.
Kuyika Mafilimu Ochepa: Hafnium tetrachloride imagwiritsidwa ntchito popanga mankhwala a vapor deposition (CVD) kupanga mafilimu opyapyala azinthu zopangidwa ndi hafnium. Mafilimuwa ndi ofunikira pa ntchito zosiyanasiyana, kuphatikizapo ma microelectronics, optics, ndi zokutira zoteteza. Kutha kuyika yunifolomu, mafilimu apamwamba kwambiri kumapangitsa HfCl4 kukhala yofunikira muzopanga zapamwamba.
