I-Hafnium tetrachloride, HfCl4, inombolo ye-CAS13499-05-3, iyinhlanganisela eye yathola ukunakwa okusabalele ngenxa yobubanzi bayo bezinhlelo zokusebenza. Ikhemikhali ihlanzekile kakhulu, isukela ku-99.9% kuya ku-99.99%, futhi iza ngesimo sempushana emhlophe ngokugeleza okuhle kakhulu. Kuyaphawuleka ukuthi ukuhlanzeka kwalesi sakhiwo kubalulekile, futhi okuqukethwe kwe-Zr kungaphansi noma kulingana ne-1000PPM (Zr ≤ 0.1%). Izinketho zangokwezifiso ziyatholakala futhi ukuze kuzuzwe amazinga e-Zr aphansi njengo-200ppm.
Enye yezinto ezisetshenziswa kakhului-hafnium tetrachlorideifana nesandulela sezitsha zobumba zokushisa okuphezulu kakhulu, ikakhulukazi emkhakheni wama-LED anamandla amakhulu. Ukuhlanzeka okuphezulu kwe-compound kanye nekhwalithi kuyenza ilungele izinhlelo ezinjalo. Ama-ceramics okushisa aphezulu kakhulu abalulekile ekukhiqizweni kwama-LED aphezulu ngoba ahlinzeka ngokuzinza okudingekayo okushisayo nokuqina okudingekayo ekusebenzeni kahle kwalawa madivayisi.
Izici eziyingqayizivele zei-hafnium tetrachlorideyenze ibe isithako esibalulekile ekwakhiweni kwezitsha zobumba ezishisa kakhulu. Ukuhlanzeka kwayo okuphezulu, umbala omhlophe kanye ne-fluidity enhle kusiza ukuthuthukisa ikhwalithi yonke ye-ceramics ekhiqizwayo. Ukwengeza, ikhono lokwenza okuqukethwe kwe-Zr ngendlela oyifisayo kuqhubeza nokuthuthukisa ukufaneleka kwakho kwezidingo ezithile zokukhiqiza.
