Ngaba i-aluminium iqhuba umbane?
I-aluminium yintsimbi eninzi kwindalo. Sisixhobo esihle sokusetyenziswa kwemizi-mveliso kunye nohlobo lwezinto zentsimbi ezinombane ofanelekileyo kunye nokuphumelela kwe-thermal. Ngaxeshanye, I-Aluminiyam inentsimbi enokuqhuba umbane. I-Aluminium inokuqhuba umbane kuba kukho inani elikhulu le-elektroni yasimahla ngaphakathi kwayo. Ezi elektroni zasimahla zihlala zenza intshukumo engaqhelekanga ye-theristal yentsimbi. Xa zichatshazelwe yintsimi yombane yangaphandle, Baza kuhamba ngendlela ekhokelela kwicala elihlukileyo kwibala lombane, ngaloo ndlela senza umbane wangoku.
I-Alumnum iqhuba njani umbane?
Yintoni umgaqo weAluminium Foil?
Umgaqo-siseko wokuqulunqwa kwe-aluminium ubukhulu ikakhulu busekwe kubume be-elektroniki yeeatom zayo kunye neempawu zentsimbi ye-metric. Zintlanu izizathu zokuba kutheni i-Alumnum inokuqhuba umbane.
1. Ubukho bee-elektroniki zasimahla
Iiatom zealuminium zinee-elektroni ezintathu ze-Electrons kwi-ofisi yazo engaphandle. Kwikristali yentsimbi, Ezi zixhobo ze-Election Electrons azixhomekeki kwi-atom ethile, kodwa inokuhamba ngokukhululekileyo kuyo yonke i-crystal yentsimbi ukuba izenzele “Ulwandle lwe-elektroni”. Ezi elektroni zihamba ngokukhululekileyo sisizathu esisisiseko sokusebenza kwezinyithi.
2. I-Andstic Bonds:
IAluminium Atom idityaniswe kunye ne-metallic Bonds. I-Bindllic Bonds luhlobo olukhethekileyo lwebhombu yekhemikhali apho i-Ions ejongiweyo nge-atom zentsimbi icwangciswa kulwandle lwee-elektroni zasimahla. Ii-elektroni zasimahla zihamba ngokukhululekileyo kuzo zonke izinto zekristale, Ukwenza ukuba le ntsimbi iqhubekeke ngombane.
3. Ukuhamba kwe-elektroni kwaye okwangoku
Xa i-voltage isetyenziswa kwiziphelo ezibini zeAluminium Opthungile, I-elektroni yasimahla iya kuhamba ngendlela ekhokelela phantsi kwesenzo sendawo yombane. Lo mbutho we-elektroni. Ngoko ke, I-aluminium iyakwazi ukwenza umbane.
4. Ulwakhiwo lwe-lattice:
Isakhiwo sekristali ye-aluminium yi-cubic agxininisayo (I-FCC) Ulwakhiwo, evumela ii-elektroni ukuba zihambe ngokukhululekileyo kwi-lattce, Ngaloo ndlela ukuphucula ukuqhutywa kwempumelelo.
5. Ukuxhathisa:
Ukuxhathisa i-aluminium iphantsi kakhulu, Malunga ne-2.65 × 10 ^ -8 ω M, engaphezulu kancinane kunobhedu (Malunga ne-1.68 × 10 ^ -8 č · m), Kodwa iseyinto elungileyo esebenzayo. Oku kuthetha ukuba i-elektroniki idlulisa abaqhubi bealuminiyam abalulekileyo.
