Hoʻolauna pōkole:

Molekala:HfO2Ka helu CAS: 12055-23-1
Maʻemaʻe: 99.9% a 99.99% Nui: 3N, 4N
Nā hiʻohiʻona huahana:ʻO Radon dioxide (HfO2) he oxide o ka mea nitride, ma ka lumi wela a ma lalo o ke kaomi maʻamau he paʻa keʻokeʻo.ʻO ka pauka keʻokeʻo, me ʻekolu mau hale aniani: hoʻokahi oblique, quad a me cubic, helu heheʻe 2780 a 2920K.Ka helu hoʻolapalapa 5400K.ʻO ka coefficient o ka hoʻonui wela he 5.8 × 10-6 degere C. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, ka waika hydrochloric a me ka waikawa nitric, hiki ke hoʻoheheʻe ʻia i ka waikawa sulfuric concentrated a me ka waikawa fluorohydroic.Loaʻa ia ma ka hoʻoheheʻe wela a i ʻole ka hydrolysis o nā pūhui e like me ka vanadium sulfate a me ka chloride oxide.ʻO nā mea waiwai no ka hana ʻana i nā mea hao a me vanadium.Hoʻohana ʻia e like me nā mea refractory, nā pale anti-radioactive a me nā catalysts.
ʻAno: ʻO ka pauka keʻokeʻo me ʻekolu mau hale aniani: hoʻokahi oblique, quad a me cubic.
E hoʻohana:ʻO nā mea waiwai no ka hana ʻana i nā mea hao a me vanadium.Hoʻohana ʻia e like me nā mea refractory, nā pale anti-radioactive a me nā catalysts.
Puke: ʻOmole
'Ōlelo Aʻo: Hiki ke hāʻawiʻia nā huahana i hoʻopilikinoʻia e like me nā koi kūikawā o ka mea kūʻai.
