Khoom cim npe

Zoo thiab piav qhia:
Hafnium oxide hmoovyog lub ntsiab oxides ntawm hafnium, nws yog cov ntxhiab tsw dawb thiab tasteless siv lead ua nyob rau hauv ib txwm muaj xwm txheej.

Lub npe: hafnium dioxide	Tshuaj formula:HfO2
Molecular Luj: 210.6	Qhov ceev: 9.68 g / cm3
Melting point: 2850 ℃	Kub taw tes: 5400 ℃

Cov khoom siv:

Hafnium oxide hmoovyog ib yam uas tsis yog-tshuaj lom thiab tasteless dawb khoom, tsis yaj nyob rau hauv dej, hydrochloric acid thiab nitric acid, soluble nyob rau hauv concentrated sulfuric acid thiab hydrogen fluoride acid; Lawv yog chemically inert, nrog nyias zaj duab xis zog: pob tshab ntau yam ~ 220 ~ 12000nm ；refractive index (250nm) ~ 2.15 (500nm)～2, nrog siab melting point, yog li nws muaj ntau yam kawg-siv.

Daim ntawv thov:

1) Raw cov ntaub ntawv rau zirconium hlau thiab nws cov tebchaw;

2) Zirconium cib, zirconium hlab, crucibles, thiab lwm yam rau melting ntawm niaj hnub ceramics, refractory cov ntaub ntawv, thiab precious hlau;

3) Thermal barrier coatings ntawm aviation thiab industrial gas turbines;

4) Zirconia kuj tseem siv tau los ua cov khoom siv rau cov khoom siv polishing, abrasive hais, piezoelectric ceramics, precision ceramics, ceramic glazes, thiab kub-kub pigments.Nws tseem yog cov khoom siv tseem ceeb rau kev yees duab X-ray, teeb pom kev zoo hauv infrared spectrometers, thiab kev xyaum dag.
