Muuqaalka iyo sharraxaadda:

Hafnium oxidewaa oksaydhyada ugu muhiimsan ee hafnium, waa crystals aan ur lahayn oo aan dhadhamin xaaladaha caadiga ah.

Magaca: hafnium dioxide	Nafaqada kiimikada:HfO2
Miisaanka molecular: 210.6	Cufnaanta: 9.68 g/cm3
Barta dhalaalka: 2850 ℃	Barta karkarinta: 5400 ℃

Guryaha alaabta:

Hafnium oxide waa nooc aan sun ahayn oo aan dhadhan lahayn oo cad oo adag, oo aan ku milmin biyaha, hydrochloric acid iyo nitric acid, ku milma sulfuric acid iyo hydrogen fluoride acid. 12000nm; index refractive (250nm) ilaa 2.15 (500nm) 2, oo leh dhibic dhalaalaysa sare, sidaa darteed waxay leedahay tiro balaadhan oo ah isticmaalka dhamaadka.

Codsiga:

1) Qalabka ceeriin ee loogu talagalaybiraha hafniumiyo xeryahooda;

2) Qalabka dib-u-celinta, dahaarka shucaaca ka-hortagga, iyo kicinta gaarka ah;

3) Dahaarka muraayadda xoogga sare.
