Raws li ib qho ntawm cov khoom siv feem ntau siv thiab rov ua dua tshiab hauv ntiaj teb, txhuas yog cov hlau tsis tshua muaj peev xwm thiab muaj ntau yam.
Cia peb paub txog aluminium tshwj xeeb.
◆ Aluminium yog qhov thib ob ntau tshaj plaws nyob rau hauv lub ntiaj teb lub crust tom qab silicon, accounting txog li 8% ntawm lub ntiaj teb crust.
◆ Aluminium muaj ntau yam kev siv, los ntawm cov zaub mov thiab dej haus cov kaus poom thiab cov xov tooj ntawm tes mus rau lub dav hlau thiab tsheb.
◆ Aluminium yog lub teeb heev, hnyav li ib feem peb ntawm cov hlau lossis tooj liab.
◆ Aluminium yog cov hlau mos uas tsuas yog siv tau rau 150 xyoo, ua rau nws yog ib qho ntawm cov hlau me tshaj plaws. Piv txwv li, tooj liab yog ntau tshaj 9, 000 xyoo.
◆ Nws yog thawj zaug muab rho tawm los ntawm Danish chemist Hans Christian Oersted nyob rau hauv 1825.
◆ Nws muaj qhov melting point ntawm 660 degrees Celsius thiab kub kub ntawm 2,519 degrees Celsius.
◆ Txhuas tiv thaiv corrosion, ruaj khov heev, thiab tuaj yeem rov ua dua yuav luag tsis muaj sijhawm.
◆ Aluminium yog ib yam khoom muaj zog heev thiab tuaj yeem ua rau cov pa oxygen. Txawm li cas los xij, es tsis txhob xeb, oxidation by-product yog ib zaj duab xis ntom ntom ntawm aluminium oxide uas tiv thaiv nws sab hauv los ntawm kev xeb ntxiv.
