Hafnium tetrachloride, HfCl4, nambala ya CAS13499-05-3, ndi gulu lomwe lalandira chidwi kwambiri chifukwa cha ntchito zake zambiri. Mankhwalawa ndi oyera kwambiri, kuyambira 99.9% mpaka 99.99%, ndipo amabwera mu mawonekedwe a ufa woyera ndi kutuluka kwabwino kwambiri. Ndikoyenera kudziwa kuti chiyero cha mankhwalawa ndi chofunikira kwambiri, ndipo zomwe zili mu Zr ndizochepa kapena zofanana ndi 1000PPM (Zr ≤ 0.1%). Zosankha zachikhalidwe ziliponso kuti mukwaniritse milingo ya Zr yotsika ngati 200ppm.
Chimodzi mwazogwiritsa ntchito kwambirihafnium tetrachloridendi kalambulabwalo wa zitsulo zopangira kutentha kwambiri, makamaka m'munda wa ma LED amphamvu kwambiri. Kuyeretsedwa kwakukulu kwapawiri ndi khalidwe lake kumapangitsa kukhala koyenera kwa ntchito zoterezi. Ma ceramics otentha kwambiri ndi ofunikira kwambiri pakupanga ma LED amphamvu kwambiri chifukwa amapereka kukhazikika kofunikira komanso kukhazikika kofunikira kuti zida izi ziziyenda bwino.
The wapadera katundu wahafnium tetrachlorideipange kukhala chinthu chofunikira kwambiri popanga zida zadothi zotentha kwambiri. Kuyera kwake kwakukulu, mtundu woyera ndi madzi abwino amathandizira kupititsa patsogolo khalidwe lazoumba zomwe zimapangidwa. Kuphatikiza apo, kuthekera kosintha zomwe zili mu Zr kumakulitsanso kukwanira kwake pazofunikira zinazake zopanga.
