I-Hafnium tetrachloride, obeye aziwe njengoi-hafnium(IV) i-chloride or HfCl4, iyinhlanganisela enenombolo ye-CAS13499-05-3. Ibonakala ngokuhlanzeka okuphezulu, ngokuvamile i-99.9% kuya ku-99.99%, nokuqukethwe okuphansi kwe-zirconium, ≤0.1%. Umbala wezinhlayiya ze-hafnium tetrachloride uvamise ukuba mhlophe noma ungabi mhlophe, nokuminyana okungu-3.89 g/cubic centimeter kanye nendawo yokuncibilika engu-432°C. Ngokuphawulekayo, ibhidliza emanzini, okubonisa ukuthi isabela ngomswakama.
I-Hafnium tetrachlorideingasetshenziswa njengesandulela ekukhiqizeni ama-ceramics okushisa aphezulu kakhulu. Eyaziwa ngokuzinza kwawo okuhle kakhulu kokushisa, lezi zobumba zisetshenziswa ezinhlobonhlobo zezicelo zokushisa okuphezulu, njengezinhlelo zokuvikela ukushisa embonini ye-aerospace kanye nokukhiqizwa kwamathuluzi okusika kanye nezinsimbi. Ikhono lenhlanganisela lokumelana namazinga okushisa aphakeme kakhulu liyenza ibe yingxenye ebalulekile ekuthuthukisweni kwezinto zobuchwepheshe obuphambili kanye nokusetshenziswa kwezimboni.
Ngaphezu kwalokho,i-hafnium tetrachlorideidlala indima ebalulekile emkhakheni wama-LED anamandla amakhulu. Isetshenziselwa ukukhiqizwa kwama-phosphors, abalulekile ekusebenzeni kwama-LED. Amaphosphor izinto ezikhipha ukukhanya lapho zivezwe emisebeni futhi zibalulekile ekusebenzeni kwe-LED ngokuguqula ukukhanya okuluhlaza kube eminye imibala, ngaleyo ndlela kuthuthukiswe ukusebenza kahle konke kanye nekhwalithi yombala wokukhanya.
Ukuhlanzeka okuphezului-hafnium tetrachloridekungenziwa ngendlela oyifisayo ukuze kuncishiswe okuqukethwe kwe-zirconium ku-200ppm, kuqinisekiswe ukuthi ilungele izinhlelo zokusebenza ezifunayo lapho ukungcola kungase kuthinte kabi umkhiqizo wokugcina. Leli zinga lokuhlanzeka libalulekile ekuhlanganisweni ngempumelelo kwezinto ezithuthukisiwe, lapho ukulawulwa okunembile kokwakheka kwamakhemikhali kubalulekile.
Ngokufigqiwe,i-hafnium tetrachloride, ngokuhlanzeka kwayo okuhle kakhulu kanye nezakhiwo eziyingqayizivele, isibe isandulela esibalulekile sokukhiqizwa kwezitsha ze-ceramics zokushisa okuphezulu kakhulu futhi idlala indima ebalulekile ekuthuthukisweni kobuchwepheshe be-LED obunamandla amakhulu. Ukuguquguquka kwayo kanye nokusebenza kabusha kuyenza ibe yingxenye ebalulekile ekuthuthukisweni kwezinto zokusebenza zezimboni nezobuchwepheshe ezisezingeni eliphezulu.
