Copper (Cuprum) yog cov khoom siv hlau, tab sis kuj yog ib qho kev hloov pauv, cov cim tshuaj Cu, lus Askiv tooj liab, atomic tooj 29. ntshiab tooj liab yog cov hlau mos, qhov saum npoo tsuas yog txiav rau cov xim liab-txiv kab ntxwv nrog cov xim hlau, cov monomers yog ntshav liab.
Zoo ductility, thermal conductivity thiab high hluav taws xob conductivity, yog li nyob rau hauv lub cable thiab hluav taws xob thiab hluav taws xob Cheebtsam yog cov feem ntau siv cov ntaub ntawv, kuj yuav siv tau raws li lub tsev cov ntaub ntawv, yuav ua tau ntau yam ntawm alloys. Copper alloys muaj cov cuab yeej zoo heev thiab tsis muaj hluav taws xob tiv thaiv, qhov tseem ceeb tshaj plaws yog tooj liab thiab tooj dag. Tsis tas li ntawd, tooj liab yog cov hlau ruaj khov thiab tuaj yeem rov ua dua ntau zaus yam tsis muaj kev poob ntawm cov khoom siv kho tshuab.
Divalent tooj liab ntsev yog cov khoom siv tooj liab ntau tshaj plaws; lawv cov hydrated ions feem ntau tshwm xiav, thaum chlorine li ligand tshwm ntsuab, thiab yog lub hauv paus ntawm cov xim ntawm cov zaub mov xws li xiav chalcopyrite thiab turquoise, uas tau siv los ua pigments thoob plaws hauv keeb kwm. Copper architectural structures yog corroded los ua ib qho tooj liab ntsuab (basic tooj liab carbonate). Cov khoom siv kho kom zoo nkauj feem ntau yog siv cov hlau tooj liab thiab tooj liab uas muaj cov xim.
Tooj liab yog ib qho ntawm thawj cov hlau siv los ntawm tib neeg. Raws li thaum ntxov ua ntej keeb kwm, tib neeg pib mining qhib-qhov tooj liab mines thiab siv tooj liab lawv tau los ua riam phom, cuab yeej, thiab lwm yam khoom siv, thiab kev siv tooj liab muaj kev cuam tshuam loj heev rau kev vam meej ntawm tib neeg thaum ntxov. Tooj liab yog ib yam hlau uas muaj nyob rau hauv lub ntiaj teb crust thiab nyob rau hauv dej hiav txwv. Cov ntsiab lus ntawm tooj liab nyob rau hauv lub ntiaj teb crust yog hais txog 0.01%, thiab nyob rau hauv ib tug neeg tooj liab deposits, cov ntsiab lus ntawm tooj liab yuav ncav cuag 3% mus rau 5%. Feem ntau ntawm cov tooj liab nyob rau hauv qhov muaj xws li cov tebchaw, xws li tooj liab ores.
Kev ua haujlwm ntawm tooj liab tsis muaj zog, hlau monomers thiab tooj liab sulfate cov tshuaj tiv thaiv tuaj yeem hloov cov tooj liab monomers. Tooj liab monomers yog insoluble nyob rau hauv non-oxidizing acids.
tooj liab ntom ntawm 8-9g/cm3; melting point 1083 degree C. Ntshiab tooj liab conductivity yog zoo heev, ntau ntawm cov xov hlau, cables, txhuam, thiab lwm yam .; zoo thermal conductivity, feem ntau siv nyob rau hauv kev tsim khoom ntawm anti-magnetic cuam tshuam nrog cov khoom sib nqus, cov twj paj nruag, xws li compasses, aviation instrumentation, thiab lwm yam.; plasticity yog qhov zoo heev, yooj yim rau kev kub thiab txias ua haujlwm tuaj yeem ua rau hauv lub raj, pas nrig, hlau, sawb, sawb, phaj, ntawv ci thiab lwm yam khoom siv tooj liab. Muaj ob hom khoom siv tooj liab ntshiab: cov khoom lag luam smelted thiab cov khoom ua tiav.
Txawm koj xav taucov kav dej tooj liab, tooj liab rods ,tooj liab daim hlau, peb muaj cov khoom thiab kev txawj ntse kom tau raws li koj xav tau.
