Aluminium Oxide yog ib qho kev sib xyaw ua haujlwm siab nrog lub melting point ntawm 2054 degree thiab boiling point ntawm 2980 degree. Nws yog ionic siv lead ua uas tuaj yeem ionized ntawm qhov kub thiab txias. Nws yog odorless thiab tasteless.
Kev tsim cov alumina yuav ua rau qee qhov kev ua qias tuaj. Cov pa phem tseem ceeb yog cov av nkos Liab, ntxiv rau kev tuav cov av ntau, cov alkali thiab sulfate hauv cov kua txuas txuas mus rau hauv av thiab av, ua rau salinization ntawm thaj av loj.
