IHafnium tetrachloride, kwaziwa njengehafnium(IV) chloride or HfCl4, yinkomponi enenombolo yeCAS13499-05-3. Ibonakaliswa ngokucoceka okuphezulu, ngokuqhelekileyo i-99.9% ukuya kwi-99.99%, kunye nomxholo ophantsi we-zirconium, ≤0.1%. Umbala wamasuntswana e-hafnium tetrachloride udla ngokuba mhlophe okanye ungekho mhlophe, kunye noxinzelelo lwe-3.89 g/cubic centimeter kunye nendawo yokunyibilika eyi-432°C. Ngokucacileyo, iqhekeza emanzini, ebonisa ukuba isabela ngokufuma.
IHafnium tetrachlorideingasetyenziswa njenge-precursor kwimveliso yeekeramics zobushushu obuphezulu kakhulu. Eyaziwayo ngokuzinza kwe-thermal egqwesileyo, ezi zeramics zisetyenziswe kwiintlobo ezahlukeneyo zokushisa okuphezulu, njengeenkqubo zokukhusela i-thermal kwishishini le-aerospace kunye nokuveliswa kwezixhobo zokusika kunye neziphambano. Isakhono sekhompawundi ukumelana nobushushu obugqithisileyo buyenza ibe licandelo elibalulekileyo kuphuhliso lwemathiriyeli yobuchwepheshe obuphambili kunye nokusetyenziswa kwemizi-mveliso.
Ngaphezu koko,i-hafnium tetrachlorideidlala indima ebalulekileyo kwintsimi yee-LED ezinamandla aphezulu. Isetyenziselwa ukuveliswa kweephosphors, ezibaluleke kakhulu ekusebenzeni kwee-LED. Iiphosphor zizixhobo ezikhupha ukukhanya xa zibonakaliswe kwimitha kwaye zibalulekile ekusebenzeni kwe-LED ngokuguqula ukukhanya okuluhlaza kweminye imibala, ngaloo ndlela kuphuculwe ukusebenza kakuhle kunye nomgangatho wombala wokukhanya.
Ubunyulu obuphezului-hafnium tetrachlorideinokwenziwa ngokwezifiso ukunciphisa umxholo we-zirconium kwi-200ppm, ukuqinisekisa ukuba ifanelekile kwizicelo ezifunwayo apho ukungcola kunokuchaphazela kakubi imveliso yokugqibela. Eli nqanaba lokucoceka libalulekile kubuchule obuphumelelayo bemathiriyeli ephucukileyo, apho ulawulo oluchanekileyo lokwakheka kweekhemikhali lubalulekile.
Isishwankathelo,i-hafnium tetrachloride, kunye nokucoceka kwayo okugqwesileyo kunye neempawu eziyingqayizivele, ibe yinto ephambili ebalulekileyo kwimveliso yeekeramics ze-ultra-high kwaye idlala indima ebalulekileyo ekuphuculeni iteknoloji ye-LED yamandla aphezulu. Ukuguquguquka kwayo kunye nokusebenza kwakhona kwenza kube yinto ebalulekileyo ekuphuhlisweni kwezixhobo zokusetyenziswa kwezoshishino kunye nezobugcisa.
