Kayan kemikal
Hafnium yayi kama da zirconium a cikin kayan kimiyyar. Yana da kyakkyawar juriya ta lalata kuma ba abu ne mai sauƙi ba wanda za'a iya kaiwa hari ta hanyar maganin ruwa na yau da kullun. Yana da sauƙin narkewa a cikin hydrofluoric acid kuma yana samar da hadadden furotin. A babban zazzabi, hafnium zai iya haɗuwa kai tsaye tare da gas kamar oxygen da nitrogen don ƙirƙirar oxides da nitrides.
AMFANI:
Hafnium na da amfani domin yana fitar da lantarki cikin sauki (misali azaman filament na fitilar rashin haske). Alloys na hafnium da tungsten ko molybdenum ana amfani dasu azaman wutan lantarki don manyan bututun fitarwa. Amfani da shi a ciki
X-ray cathode da masana'antun masana'antu na tungsten. Hafnium mai tsabta yana da filastik, mai sauƙin aiwatarwa, juriya mai zafin jiki da juriya ta lalata, abu ne mai mahimmanci a masana'antar makamashin atom. Hafnium thermal neutron capture giciye sashi shine ingantaccen tsinkayen ruwa, wanda za'a iya amfani dashi azaman sandar sarrafawa da na'urar kariya a atomic reactor
Hafnium foda ACTS a matsayin mai kara ƙarfin roka. Cathodes na X-ray tubes za a iya kerarre a cikin masana'antar lantarki. Za'a iya amfani da gami na Hafnium a matsayin masu tsaron gaban rokoki da motocin sake shigowa, kuma ana iya amfani da allunan HF-TA don yin ƙarfe da kayan aiki masu ƙarfi.
Ana amfani da Hafnium azaman ƙari a cikin gami mai jure zafi, kamar tungsten, molybdenum, da tantalum. Ana iya amfani da HfC azaman ƙari na carbide saboda tsananin tauri da narkar da shi. Matsayin narkewa na 4TaCHfC yana da kusan 4215 which, wanda shine sanannen sanannen mahaɗin sinadarai. Ana amfani da Hafnium a matsayin mai karɓar ruwa a cikin tsarin tsarkewa da yawa. Hafnium getter yana cire oxygen, nitrogen, da sauransu daga tsarin ba tare da gas ba. Ana amfani da Hafnium sau da yawa, azaman ƙari a cikin mai na hydraulic don hana ɓarkewar mai a cikin haɗarin haɗari, tare da ƙaƙƙarfan anti-volatilization, wannan halayyar, don haka ana amfani da ita gabaɗaya a cikin man na na'ura mai aiki da karfin ruwa.
