Palladium - sau txog kev paub txog palladium

Palladium tsawg paub txheeb ze ntawm platinum thiab kub. Nws yog ib qho ntawm cov hlau muaj nqi tshaj plaws hauv ntiaj teb. Nws tau hu nws rau qee lub sijhawm nrov nrov raws li cov khoom siv raw rau kev tsim cov hniav nyiaj hniav kub, nrog rau kev nqis peev hlau. Dab tsi ua rau nws nrov. Yog li palladium yog dab tsi thiab koj yuav tsum paub dab tsi txog nws?

Kev siv palladium

Hauv xyoo 90s thiab thaum ntxov xyoo pua XNUMX, ntau palladium Lawv feem ntau yog txuam nrog catalytic converters hauv tsheb lossis nrog kev lag luam tshuaj. Metallic palladium thiab nws cov tebchaw yog qhov tseem ceeb hauv catalysis. Yog li ntawd, lawv pab txhawb kev khiav ntawm ntau cov tshuaj tiv thaiv. Yav dhau los, cov hlau no tau siv los ntawm jewelers. rau zus tau tej cov dawb kub. Nws muaj peev xwm tshem tawm nws cov xim daj, thiab tib lub sijhawm nws kuj yog "noble".

Cov tsos thiab cov yam ntxwv ntawm palladium

Palladium muaj cov yam ntxwv ntawm cov hlau. Nws yog malleable, malleable, silver grey thiab muaj lub siab sheen. Nws tsis yog reactive heev nyob rau hauv chav tsev kub yog li nws yog zoo tagnrho rau ua palladium rings los yog kab tshoob bands. Los ntawm kev tshawb fawb pom, cov cuab yeej zoo tshaj plaws ntawm palladium yog nws lub peev xwm los yaj cov roj hydrogen ntau. Hauv 1 ntim ntawm palladium, 900 ntim roj tuaj yeem yaj. Qhov no zoo ib yam li muab 900 lub lauj kaub qab zib rau hauv ib lub thawv dej.

Palladium hniav nyiaj hniav kub thiab lwm yam kev siv

Palladium yog cov khoom siv raw rau kev tsim cov hniav nyiaj hniav kub tau siv txij li xyoo 30s. Txawm li cas los xij, thaum xub thawj nws tsuas yog siv los ua ib qho ntxiv rau platinum thiab kub. Raws li tus nqi rau ob qho khoom kim tshaj plaws hlau tau mus txog cov ntaub ntawv tshiab, jewelers txiav txim siab los ua palladium lawv cov neeg sib tw sib npaug. Qhov nrov ntawm cov hlau no txuas ntxiv mus tas li, tab sis ntawm qhov qeeb qeeb qeeb. Qhov no yog tej zaum vim hais tias nws yog me ntsis-paub hlau, thiab kuj vim hais tias nws yog ntau nyuaj rau txheej txheem ntau tshaj li lwm tus. Palladium kab tshoob nplhaib yog nrov heev.

Txawm li cas los xij, nws yuav tsum tau sau tseg tias Txawm hais tias palladium yog qhov tseem ceeb tshaj nyiaj, nws kuj tsis tshua ruaj khov (piv txwv li ntau reactive) dua li kub thiab platinum thiab yog li kev tsis haum tshuaj tuaj yeem tshwm sim. Tshwj xeeb tshaj yog cov neeg muaj kev fab tshuaj rau lwm cov hlau (piv txwv li, npib tsib xee) yuav tsum xyuas ua ntej yuav. seb palladium tsis hnov ​​lawv. Palladium kuj tseem siv los tsim kub nib platings yog tias tus neeg siv khoom xav tau nyiaj nib es tsis txhob kub.
