Txheej txheem cej luam
Tooj liab yog cov hlau uas muaj xim liab-liab luster, ntom: 8.92g / cm³, melting point: 1083.4 ± 0.2 ℃, boiling point: 2567 ℃. Tooj yog ib qho nyuaj me ntsis, tawv heev, hnav-resistant, muaj ductility zoo, zoo thermal conductivity, hluav taws xob conductivity thiab corrosion kuj. Tooj thiab nws cov alloys ruaj khov nyob rau hauv cov huab cua qhuav, tab sis nyob rau hauv cov huab cua ntub ib txheej ntawm ntsuab yooj yim tooj liab carbonate Cu₂ (OH) ₂CO₃ yuav tsim nyob rau saum npoo, feem ntau hu ua patina.
Cov Khoom Siv: Cov tooj liab ntshiab yog xim liab-xim av uas tsim cov patina ntsuab thaum raug corrosive ib puag ncig. Qhov ntsuab tooj liab sulfate (los yog tooj liab carbonate) yog tsim los ntawm cov txheej txheem tshuaj los ntawm alkalis, ammonia, sulfate tebchaw thiab acidic rainwater. Thaum patina ntawm tooj liab yog lub cim ntawm corrosion, nws tiv thaiv cov hlau los ntawm kev puas tsuaj ntxiv.
Daim ntawv thov: Sputtering lub hom phiaj, high-purity alloys, qauv qauv, integrated circuit ntim kab, high-zoo suab kab thiab lwm yam teb.
