I metal conductive kakhulu emhlabeni

Inani izinsimbi kunqunywa ngokuqondile chemical zabo nezindawo ngokomzimba. Endabeni isilinganiso esinjalo, njengoba conductivity kagesi, ubudlelwane akuyona kuqondile ngakho. metal conductive Iningi, uma inkomba kulinganiswa ekamelweni lokushisa (+20 ° C), - esiliva. Kodwa zibiza kukhawulela ukusetshenziswa izingxenye isiliva kagesi kanye Microelectronics. izakhi Isiliva amadivayisi enjalo isebenza kuphela uma bakwazi kwezomnotho.

Okwakushiwo ezingokomzimba conductivity

Ukusetshenziswa babashayeli metallic inomlando osekukade. Ososayensi futhi onjiniyela basebenza emasimini ngesayensi nobuchwepheshe, usebenzisa amandla kagesi isikhathi eside ukunquma izinto sezintambo, ezikhumulweni, oxhumana nabo, wesifunda amabhodi ephrintiwe , nokunye. D. Thola metal conductive kakhulu emhlabeni kusisiza ubuningi ngokomzimba ebizwa ngokuthi conductivity kagesi.

Concept conduction emuva ukumelana kagesi. Quantitative Inkulumo conductivity elihlobene ne iyunithi ukumelana, lapho uhlelo lomhlaba wonke amayunithi (SI) ulinganiswa ohms. Iyunithi conductivity kagesi kuleli SI - Siemens. ukuqokwa Russian yalolu phiko - Bheka, international - conductivity S. Electric 1 cm ingxenye has inethiwekhi kagesi nge ukumelana 1 ohms.

Kukala ikhono into ukuqhuba kagesi ngokuthi conductivity. The esiphezulu kule inkomba has kwensimbi conductive kakhulu. Lesi sici kungaba azimisele ngoba zonke izinto noma naphakathi instrumentally futhi inkulumo ezinombolo. Conductivity cylindrical umqhubi iyunithi ubude iyunithi endaweni cross-Sectional ihlobene resistivity ka umqhubi.

System iyunithi conductivity kuyinto Siemens imitha ngalinye - S / m. Ukuze uthole ukuthi yikuphi insimbi metal conductive kakhulu emhlabeni, ngokwanele ukuqhathanisa conductivity zabo, kunqunywa Ucwaningo. Omunye lungacacisa resistivity esebenzisa idivayisi ekhethekile - microohmmeter. Lezi zimo zokuma kukhona ephambene.

conductivity of izinsimbi

Wona kanye umqondo welithi kagesi njengoba ukugeleza iqondiswe izinhlayiya icala kubonakala izinto ivumelane ngaphezulu esekelwe crystal ngamahele izinsimbi esingokwemvelo. Shaja abathwali lapho i kagesi e insimbi kukhona electron mahhala futhi ion akuzona, njengoba kwenzeka ngo-media liquid. Yasungulwa Ucwaningo ukuthi lapho wamanje ingekho izinsimbi particulate izidakamizwa ukudluliswa phakathi babashayeli.

izinto zensimbi zihluke nezinye izibopho ngaphezulu khulula ezingeni le-athomu. Idivayisi kwangaphakathi metal libhekene khona inani elikhulu "ibalula" electron. okuyinto, lapho zihlatshwa ifomu kancane amabutho kagesi iqondiswe flow. Ngakho-ke, akusona izinsimbi Yingakho kukhona babashayeli kangcono kagesi, nokuthi ekusebenzisaneni yamangqamuzana enjalo kuhluke metal conductive kakhulu. On izici isakhiwo crystal ngehele lomunye metal based izakhiwo zabo ethize - okusezingeni eliphezulu ukushisa conductivity.

Top babashayeli engcono - izinsimbi

4 metal kokuba Siwusizo ukusetshenziswa njengoba babashayeli kagesi anikezwa ngendlela elandelayo ezidlula mayelana conductivity, ulinganiswa cm / m:

1. Silver - 62,5 million.
2. Copper - 59,5 million.
3. Igolide - 45,5 million.
4. Aluminium - 38 million.

It kuyabonakala ukuthi metal conductive kakhulu - esiliva. Kodwa efana negolide, isetshenziswa ukusungula inethiwekhi kagesi kuphela ezimweni ezikhethekile, ethize. Isizathu - zibiza.

Kodwa ikhopha ne-aluminiyamu - ukhetho ezivamile imikhiqizo kagesi kanye ikhebula ngenxa ukumelana yabo ongaphakeme ukuba kagesi kanye ukuyikhokhela. Okunye izinsimbi ezisetshenziswa njengoba babashayeli ezingavamile.

Ingabe Zikhona Izimo Ezenza ezinomthelela conductivity of izinsimbi

Ngisho metal conductive kunciphisa conductivity yayo lapho abakhona nezinye izithasiselo futhi akhiphe amanyela. Ngo Alloys ngaphandle "ukuhlanzeka" isakhiwo ngehele metal. It ahluke ayephuli wesimethri uqhekeke nezinye zamehlo. I conductivity kuyehla nalapho ukwanda kuma lokushisa.

Ukumelana Ukwandiswa esivela Alloys isetshenziswa Ukushisa izakhi. Akukhona ukuthi kumane kuqondane womshini izakhi yokusebenza kagesi, asetshenziselwa heater nichrome, fechral nezinye Alloys.

metal Iningi conductive - lokhu esiliva eziyigugu eside esetshenziswa Jewelers, ayenza lezi njll Nokho, le nqubo abese insimbi yawo yamakhemikhali ethize kanye Izakhiwo ezisetshenziswa kabanzi ... Ngokwesibonelo, ngaphandle usebenzisa ISIZINDA kanye lokubolekwa nge ongaphakeme ukumelana esiliva enamathela kuvimbela ukuxhumana kwesigcawu kusukela namachibi. I izakhiwo esiyingqayizivele isiliva Alloys yayo ngokuvamile balisebenzisa kulingane, naphezu kwezindleko nomsebenzi omkhulu.
