Palladium CAS 7440-05-3 Pd ≥9.75%

Palladium (CAS: 7440-05-3) yog ib qho kev hloov pauv ntawm pawg III (nickel pab pawg) thiab lub teeb platinum hlau nyob rau hauv lub sij hawm.Nws yog nruab nrab-nyuaj, nruab nrab-forgeable thiab ductile silver-white hlau.Ntau yam ntawm nws cov khoom zoo ib yam li cov hauv pawg no.Nickel saum nws thiab platinum hauv qab nws.Palladium yog cov hlau mos nyiaj-dawb uas nws cov khoom siv tshuaj thiab lub cev zoo ib yam li platinum.Nws yog malleable thiab malleable, uas txhais tau hais tias nws tuaj yeem ua tiav rau hauv cov ntawv nyias thiab ncab rau hauv cov hlau nyias nyias los ntawm kev tuag.Palladium lub peev xwm los nqus cov hydrogen ntau ua rau nws ua tau zoo heev catalyst forchemical reactions as well as catalytic converters for internal combustion engines.Palladiumis kuj yog ib qho zoo heev catalyst rau cracking petroleum feem thiab rau hydrogenation ntawm kua zaub roj rau hauv cov ntaub ntawv, xws li pob kws roj rau hauv margarine.Nws kuj yog siv los purify hydrogen roj los ntawm kev dhau cov roj H2 raw nyob rau hauv siab los ntawm cov nplooj ntawv nyias ntawm palladium, qhov uas cov ntshiab hydrogen hla los ntawm cov hlau siv lead ua qauv, tawm hauv qab impurities.Palladium yog siv los tsim cov khoom siv CO-saib xyuas vim nws muaj peev xwm nqus carbon monoxide.Palladium yog siv rau hauv kev tsim cov cuab yeej phais, kev sib cuag hluav taws xob, lub caij nplooj ntoos hlav rau lub caij nplooj ntoos hlav thiab lub moos, cov khoom siv hluav taws xob zoo, thiab cov xov hlau tshwj xeeb thiab ua "dawb kub" hauv cov hniav nyiaj hniav kub.Vim nws yog noncorrosive, nws yog siv los ua ib txheej rau lwm yam hlau thiab ua hniav fillingsand crowns.Feem ntau yog siv los ua cov catalysts, tab sis kuj ua cov ntaub ntawv kho hniav, saib thiab cov cuab yeej phais, thiab lwm yam.Siv rau hauv cov khoom siv hluav taws xob, precision alloys, thiab lwm yam.Muaj kev siv xws li hluav taws xob ntsuas, tshuaj lom neeg kev lag luam thiab kev tsim precision alloy.
