Tooj liab hauv peb lub neej niaj hnub yog ib qho kev hloov pauv. Ntshiab tooj liab yog cov hlau mos nrog cov xim liab, zoo ductility, siab thermal thiab hluav taws xob conductivity. Nws yog cov khoom siv feem ntau siv rau cov cables thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, nrog rau siv los ua cov khoom siv hauv tsev thiab tuaj yeem tsim ua ntau yam alloys. Tooj liab kuj yog cov hlau ruaj khov uas tuaj yeem siv tau ntau zaus yam tsis muaj kev cuam tshuam nws cov khoom siv kho tshuab.
Cov khoom ntawm tooj liab hlau: tooj liab, nrog lub npe Askiv: tooj liab, lub cim cim Cu, atomic hnyav 63.546, yog pawg IB hlau. Qhov ceev ntawm 8.92 g / cm3, melting point ntawm 1083.4 & plusmn0.2 degree, boiling point ntawm 2567 degree, tooj liab yog ib tug hlau nrog ib tug liab doog luster, me ntsis nyuaj, heev tawv, hnav-resistant, nrog zoo ductility, zoo thermal conductivity, hluav taws xob conductivity thiab corrosion kuj. tooj liab thiab nws cov alloys ruaj khov nyob rau hauv cov huab cua qhuav, tab sis nyob rau hauv cov huab cua ntub yuav tsim ib tug ntsuab txheej ntawm alkaline tooj liab carbonate Cu2 (OH) 2CO3 ntawm nws nto, feem ntau hu ua tooj liab ntsuab.
Chalcopyrite yog tooj liab-hlau sulfide ntxhia. Cov tshuaj formula CuFeS2, feem ntau muaj cov cim ntawm kub, nyiaj, thiab lwm yam.. Crystals kuj tsis tshua muaj, tetrahedral; feem ntau tsis sib xws granular, ntom loj aggregates, tab sis kuj raum-puab, txiv hmab txiv ntoo-puab aggregates. tooj dag, nrog xiav thiab purplish-xim av me ntsis ntawm qhov chaw; ntsuab streaks; metallic luster, opaque; tsis muaj cleavage; conductive. Hardness 3 mus rau 4, nkig, txheeb ze ntom ntom 4.1 txog 4.3.
Hom Copper Deposits: Tooj nyob rau hauv cov xwm yog muab faib ua ntuj tooj liab, oxidized tooj liab thiab tooj liab sulfide. Cov tebchaw muaj xws li: tooj liab hydroxide, tooj liab oxide thiab tooj liab sulfate.
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.
