Yuav ua li cas txhim kho lub paj liab?

Txhim kho cov reactivity ntawm ferric oxide nrogZr02yog lub hauv paus ntawm cov txheej txheem synthesis ntawm coral liab. Lub ntsiab lus tseem ceeb ntawm cov txheej txheem no yog: Ua ntej tua hluav tawsZr02thiab hlau oxide ntawm qhov kub thiab txias. Siv txoj kev qhuav rau pregrindZr02thiab hlau oxide. Xaiv cov hlau oxide ntau dua.

DTA tau pom tias cov khoom xyaw ntawm zirconium hlau liab (coral liab) reacted ntawm 300 degree , 410 degree , 570 degree thiab 700 degree .Pre-fireZr02thiab ferric oxide ntawm 570 degree .Tom qab ntawd nws tuaj yeem tau txais kev txhim kho coral liab los ntawm kev ntxiv SiO2 thiab mineralizer.

Kev txhim kho zirconium coral liab cov khoom siv kuj tuaj yeem tau los ntawm kev sib xyaw hlau oxide thiabZr02los ntawm cov pob zeb qhuav ua ntej npaj cov khoom siv xim.Cov txheej txheem ntawm premixing tag nrho cov ntaub ntawv raw nrog pob zeb tsis muaj cov nyhuv saum toj no.

Tus nqi liab (a) ntawm cov khoom siv paj yeeb liab ua los ntawm cov hlau oxide daj (FeOOH) yog siab dua qhov uas ua los ntawm cov hlau oxide liab (Fe2O3). a) ntawm cov xim hluavtaws.

Cov neeg tau txais qhov txwv tsis pub tshaj ntawm zirconium hlau liab (coral liab) cov ntaub ntawv los ntawm cov txheej txheem saum toj no.Qhov tseem ceeb ntawm cov thev naus laus zis no yog los xyuas kom meej cov tshuaj tiv thaiv ntawm cov hlau oxide thiab Zr02 siv qhov chaw ntau dua thiab ua tiav.Qhov kub zoo tshaj plaws ntawm cov tshuaj tiv thaiv yog 570 degree. los ntawm pre-firing.
