Platinum thiab Palladium

los ntawm Ben SmyeonAugust 1, 2019

Platinum yog qhov zoo tshaj plaws paub PGM, feem ntau rau nws siv nyob rau hauv cov hniav nyiaj hniav kub. Nws yog ntawm cov pawg ntawm cov pab pawg, nrog rau iridium thiab osmium, nrog lub siab tawg thiab kub muaj kev kub ntxhov.

Qhov tseeb, platinum yog 11 per cim denser dua li kub thiab ib ncig ob zaug qhov hnyav ntawm tib lub ntim nyiaj los yog hmoov txhuas. Platinum lub chaw ruaj khov thiab tsis tshua muaj cov khoom haum rau cov khoom siv hluav taws xob thiab cov ntawv thov, thiab kev siv kho mob vim nws qhov kev nyab xeeb siab.

Platinum kuj tseem tiv taus corrosion oxidation. Lub ntsiab kev muaj peev xwm ua tau zoo oxidation catalyst yog vim li cas tom qab nws muaj koob meej hauv kev tsim khoom ntawm catalytic converters. Tseeb, ib qho ntawm kev siv zoo tshaj plaws ntawm PGMs yog raws li kev tswj hwm tsheb emission tswj catalysts - cov catalyze nitrogen oxide (NOx) rau nitrogen thiab oxidise carbon monoxide thiab hydrocarbons. Lwm yam kev thov siv tsheb rau platinum nrog cov pa pa hluav taws thiab cov pa hluav taws xob.

Palladium - mos, silvery-dawb hlau - tseem siv hauv catalytic converters hloov chaw rau cov platinum kim tshaj. Nws yog lub npe hu ua feem ntau cov tshuaj tiv thaiv corrosion tshaj plaws, thiab tuaj yeem tiv thaiv cov ntsev, oxides thiab ntxhia kua qaub tab sis cuam tshuam los ntawm sodium chloride thiab sodium cyanide. Nws tseem muaj qhov chaw siab melting - txawm tias qhov qis tshaj plaws ntawm txhua qhov ntawm platinum pab pawg hlau - thiab tsis kam tiv thaiv kev deformation uas ua rau muaj txiaj ntsig zoo rau kev ntxiv dag zog alloys.

Palladium lub peev xwm tshwj xeeb nqus dej hydrogen yog qhov muaj txiaj ntsig zoo rau cov txheej txheem tshuaj lom neeg uas muaj kev sib koom nrog hydrogen pauv ntawm ob lub tshuaj tiv thaiv - piv txwv li tsim cov khoom nyoos rau cov hluavtaws roj hmab thiab nylon. Lub sijhawm no, lub xov tooj cua isotope ntawm palladium tseem tab tom sim tshuaj kho tus mob qog mis thiab prostate.
