Aluminium (AL) tau cais raws li cov hlau vim tias nws ua pov thawjCov Khoom Siv Tseem CeebUas txhais tau nws yog xim hlau ntsiab:
1. Atomic qauv & Tsevneeg
Kev teeb tsa hluav taws xob: Txhuas muaj 3 lub peev hluav taws xob (electron configuration: [ne] 3s² 3p¹). Zoo li txhua tus hlau, nws yooj yimLoses ElectronsLos uayeem(Al³⁺), enabling metallic kev sib koom tes.
Nws yog xim hlau sib: Nws cov atoms faib tawm "hiav txwv" ntawm cov tshuab hluav taws xob hauv hluav taws xob, uas muab cov hlau ua lawv cov yam ntxwv muaj zog, thiab kev ua haujlwm zoo.
2. Cov Khoom Siv Lub Cev
Kev coj ua: Cov neeg ua yeeb yam zoo tshaj plaws ntawm tshav kub thiab hluav taws xob (siv nyob rau hauv cov kab hluav taws xob, cantware).
Mallabability & Ductility: Tuaj yeem muab hammered rau hauv nyias nplooj ntawv (ntawv ci) los yog kos rau hauv xov hlau tsis muaj tawg.
Luster: Freshly txiav txhuas muaj qhov ci ci ci (xim hlau lug).
Ceev: Lub teeb yuag (2.7 g / cm³), tab sis qhov no tsis tsim nyog nws-hlau sib txawv ntawm qhov ceev (piv txwv li, lithium yog sib dua).
3. Kev coj cwj pwm
Kev xav tau: Reacts nrog oxygen los ua ib txheej oxide tiv thaiv (al₂o₃), tiv thaiv ntxiv kev txhim kho corrosion-ib qho kev pom hauv ntau cov hlau.
Hloov kho hydrogen: Reacts nrog cov kua qaub los ua hydrogen roj (piv txwv li}}}}}} h₂↑), ib tus cwj pwm hlau classic.
4. Txoj hauj lwm nyob rau hauv lub rooj ntu
Aluminium yog nyob rau hauvPab Pawg 13(Tom qab hloov cov hlau), uas suav nrog cov hlau zoo li gallium thiab indium. Nws qhov kev tso kawm tau xav txog nws cov qauv ua qauv hlau thiab kev daws teeb meem hluav taws xob.
5. Ntau Lawm & Siv
Rho tawm ntawmelololsissis(Hall-hérice cov txheej txheem) los ntawm Bauxite Ore-ib txoj kev ua rau cov hlau reactive.
Cov ntawv thov zoo li lub cev aircraft lub cev, cov kaus poom, thiab cov ntawv ci cia siab rau nwsNws yog xim hlau zog(Lub zog, conductivity, muaj peev xwm).
