Hafnium oxide HfO2 ufa

Chithunzi cha CAS 12055-23-1HfO2ufa wa hafnium oxide ufa

Chiyambi chachidule:

Molecular:HfO2Nambala ya CAS: 12055-23-1
Chiyero: 99.9% mpaka 99.99% Kukula: 3N, 4N
Makhalidwe azinthu:Radon dioxide (HfO2) ndi okusayidi wa chinthu cha nitride, kutentha kwa firiji komanso pansi pa kupanikizika kwabwino kumakhala kolimba koyera. ufa woyera, wokhala ndi makristalo atatu: oblique imodzi, quad ndi kiyubiki, malo osungunuka 2780 mpaka 2920K. Malo otentha 5400K. The coefficient of thermal expansion ndi 5.8 × 10-6 madigiri C. Insoluble m'madzi, hydrochloric acid ndi asidi nitric, sungunuka mu concentrated sulfuric acid ndi fluorohydroic acid. Amapezeka ndi kuwonongeka kwamafuta kapena hydrolysis ya mankhwala monga vanadium sulfate ndi chloride oxide. Zida zopangira zitsulo ndi vanadium alloys. Amagwiritsidwa ntchito ngati zida zotsutsa, zokutira zotsutsa-radioactive ndi zothandizira.
Maonekedwe: ufa woyera wokhala ndi makristalo atatu: oblique imodzi, quad ndi cubic.
Gwiritsani ntchito:Zida zopangira zitsulo ndi vanadium alloys. Amagwiritsidwa ntchito ngati zida zotsutsa, zokutira zotsutsa-radioactive ndi zothandizira.
Kupakira: Kumabotolo
Zindikirani: Zogulitsa makonda ndi ma CD zitha kuperekedwa malinga ndi zofunikira za kasitomala.
