ʻO ka pauka Hafnium oxide HfO2 CAS 12055-23-1
ʻO ka fO2 kahi oxide o ka element nitride, ma ka mahana o ka lumi a ma lalo o ke kaomi maʻamau he mea paʻa keʻokeʻo. Hoʻoheheʻe ʻole ʻia i ka wai, ka waikawa hydrochloric a me ka waikawa nitric, hoʻoheheʻe ʻia i loko o ka waikawa sulfuric i hoʻopaʻa ʻia a me ka waikawa fluorohydroic. Loaʻa ia ma o ka decomposition thermal a i ʻole hydrolysis o nā hui e like me vanadium sulfate a me chloride oxide. Nā mea maka no ka hana ʻana o nā metala a me nā vanadium alloys. Hoʻohana ʻia ma ke ʻano he mau mea refractory, nā uhi anti-radioactive a me nā catalysts.
