Mawonekedwe ndi Kufotokozera:
Hafnium oxidendiye ma oxides akulu a hafnium, ndiye kristalo woyera wopanda fungo komanso wopanda kukoma nthawi zonse.

Dzina: hafnium dioxide	Chemical formula:HfO2
Molecular kulemera: 210.6	Kulemera kwake: 9.68 g/cm3
Malo osungunuka: 2850 ℃	Malo otentha: 5400 ℃

katundu katundu:

Hafnium oxidendi mtundu wa sanali poizoni ndi zoipa olimba woyera, osati kupasuka m'madzi, asidi hydrochloric ndi asidi nitric, sungunuka mu anaikira sulfuric asidi ndi wa hydrogen fluoride asidi; Iwo ndi mankhwala inert, ndi katundu woonda filimu: mandala osiyanasiyana ~ 220 ~ 12000nm ;refractive index (250nm)～2.15 (500nm)～2, yokhala ndi malo osungunuka kwambiri, kotero ili ndi mitundu ingapo yogwiritsa ntchito kumapeto.

Ntchito:

1) Zopangira zitsulo za zirconium ndi mankhwala ake;

2) Njerwa za Zirconium, machubu a zirconium, crucibles, ndi zina zotero zosungunula zitsulo za tsiku ndi tsiku, zipangizo zokana, ndi zitsulo zamtengo wapatali;

3) Zotchingira zotchinga zotenthetsera pa ndege ndi ma turbines a gasi a mafakitale;

4) Zirconia ingagwiritsidwenso ntchito ngati matrix opangira kupukuta, particles abrasive, ceramics piezoelectric, ceramics precision ceramics, ceramic glazes, ndi inki yotentha kwambiri.Ndiwonso zida zazikulu zojambulira ma X-ray, nyali zowunikira mu ma infrared spectrometer, ndi zobowolera.

Miyezo yabwino:

Muyezo wabizinesi: Nuclear grade zirconia chemical composition mass gawo/%
