CAS 12055-23-1HfO2pauda hafnium oxide pauda

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, melting point 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 iā ia ma ka decomposition thermal a i ʻole hydrolysis o nā pūhui e like me ka vanadium sulfate a me ka chloride oxide. Nā mea waiwai no ka hana ʻana i nā mea hao a me vanadium. Hoʻohana ʻia e like me nā mea refractory, anti-radioactive coatings a me nā catalysts.
ʻAno: ʻO ka pauka keʻokeʻo me ʻekolu mau hale aniani: hoʻokahi oblique, quad a me cubic.
E hoʻohana:Nā mea waiwai no ka hana ʻana i nā mea hao a me vanadium. Hoʻohana ʻia e like me nā mea refractory, anti-radioactive coatings 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.
