Tsib yam ntxwv ntawm high-purity alumina hmoov

1. Tshuaj tiv thaiv;
2. High-purity alumina, cov ntsiab lus alumina yog ntau dua 99%;
3. Kub kub tsis kam, ib txwm siv ntawm 1600 ℃, luv luv 1800 ℃;
4. Resistant rau tam sim ntawd txias thiab kub, tsis yooj yim rau tawg;
5. Nws txais yuav grouting thiab muaj siab ceev.
1. Kev siv α-hom alumina hmoov

Nyob rau hauv cov iav siv lead ua ntawm α-hom alumina hmoov, cov pa oxygen ions tau zoo ntim rau hauv hexagons, thiab Al3 + yog symmetrically faib nyob rau hauv lub octahedral coordination center ncig los ntawm oxygen ions.Lub lattice zog yog loj heev, yog li lub melting point thiab boiling point yog siab heev.α-hom oxidation Aluminium yog insoluble hauv dej thiab kua qaub.Nws tseem hu ua aluminium oxide hauv kev lag luam.Nws yog cov khoom siv yooj yim rau kev ua hlau aluminium;nws kuj yog siv los ua ntau yam refractory bricks, refractory crucibles, refractory hlab, thiab kub kub ntsuas ntsuas;nws kuj tseem siv tau ua abrasives thiab nplaim retardants.Cov neeg sawv cev, cov khoom ua kom zoo, thiab lwm yam;high-purity α-hom alumina kuj yog cov khoom siv raw rau kev tsim cov khoom siv dag zog corundum, dag ruby ​​​​thiab sapphire;nws kuj yog siv rau zus tau tej cov niaj hnub loj-scale integrated circuits.

Activated alumina muaj peev xwm xaiv adsorption rau roj, dej vapor thiab qee cov kua dej noo.Tom qab cov adsorption yog saturated, nws tuaj yeem rov qab los ntawm cua sov ntawm li 175-315 ° C kom tshem tawm dej.Adsorption thiab sawv rov los yuav ua tau ntau zaus.Ntxiv nrog rau kev siv los ua cov desiccant, nws tseem tuaj yeem nqus cov pa ntawm cov roj lubricating los ntawm cov pa pa phem, hydrogen, carbon dioxide, nkev roj, thiab lwm yam. Nws tuaj yeem siv los ua catalyst thiab catalyst carrier thiab chromatography carrier.

Alumina hmoov yog cov khoom siv tseem ceeb rau kev tsim cov txhuas ingots.Nws muaj cov yam ntxwv ntawm lub teeb ya, zoo fluidity, yooj yim dissolution thiab muaj zog fluorine nqus.Nws yog tsim rau zus tau tej cov hlau txhuas los ntawm molten ntsev electrolysis.Nws tseem yog ib qho tseem ceeb raw khoom rau zus tau tej cov corundum, ceramics thiab refractories.
