Yuav ua li cas txhim kho Zr-Pr daj
Thaum ntxov xyoo,zirconium - praseodymiumpigmentsfeem ntaumuaj axim avsuab. Txog rau 50s lig,neegThaum kawg tsim cov xim daj zircon, uas yog zirconium praseodymium daj (Pr-Si-Zr).
Xyoo 1952, ib tus kws tshawb fawb Nyij Pooj tau tsim cov txiv qaub daj zirconite puag xim nyob rau hauv qhov kub thiab txias synthesis los ntawm kev ntxiv cov av tsis tshua muaj sib tov nrog praseodymium rau zirconium dioxide thiab silicon dioxide. Plaub xyoos tom qab, peb thaum kawg tsim cov zirconite daj xim uas yog synthesized los ntawm kev ntxiv NaCl thiab Na.2MOO4Raws li tus neeg sawv cev tshuaj nyob rau hauv cov khoom saum toj no.Qhov kev tshawb fawb no kuj pom tau tias lub ntiaj teb tsis tshua muaj hlau praseodymium oxide tuaj yeem siv los ua kom cov txiv qaub daj daj zirconium puag xim.Lanthanum oxide thiab cerium oxide darken xim, thaum rubidium oxide muaj qhov nqus siab tshaj ntawm 580nm. , uas hloov cov xim daj.Ntxiv ib qho nyiaj ntawm alkali hlau oxide, fluoride los yog bromide raws li oxidant tuaj yeem txo qhov kub thiab txias thiab txhim kho cov xim zoo nkauj.
Zoo li cov khoom siv xiav vanadium zirconium, lub ntsiab crystalline theem tom qab cov xim raug rho tawm haujlwm yog zirconite.Zircon - praseodymium daj muaj xim daj daj, thiab nws lub suab tsis hnov tsw rau qhov piv ntawm ZrO.2 thiabSiO2. Thiab qhov ntxiv ntawm praseodymium oxide yog txwv, tsis pub ntau tshaj 5 feem pua.
Piv nrog rau lwm cov kub kub ceramic daj xim, zirconium praseodymium daj xim yog ntau meej thiab ci.Lawv tsis muaj xim liab ntawm tin vanadium daj los yog daj xim av ntawm zirconium yellow.Cov spectral reflectance nkhaus ntawm cov khoom xim qhia tias qhov siab tshaj plaws reflectance. yog nyob ntawm 560nm.Thiab qhov kev hloov ntawm kev xav ntawm cov xim nyob rau hauv lub liab thiab ntsuab wavelength ntau yog ntau me dua li nyob rau hauv lub ntev daj wavelength cheeb tsam.Thiab tib lub sij hawm, zirconium praseodymium daj. muaj qhov dav heevdaim ntawv thovkub.Zirconium praseodymium daj tau dav siv los ua xim glaze. Kev khiav hauj lwm kub yog SK06 cone rau SK12 cone (980 ~ 1350 degree).
Zircon series ntawm cov ximmuajkev sib raug zoo heev.Nwstuaj yeem siv dav kom phim cov xim sib haum xeeb.Yog tias vanadium zirconium xiav thiab zirconium praseodymium dajyogtov nyob rau hauv ib qho kev faib ua feemrauua xim ntsuab, nws zoo nkaus li ci ntsuab hauv glaze.Cov xim ions hauv zirconite pigments nkag mus rau ZrSiO4lattice thaum tsim ZrSiO4ntawm Zr02and SiO2nyob rau hauv qhov kev txiav txim ntawm mineralizer.
