Thaum muas bismuth trioxide, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus tseem ceeb xws li purity, siv lead ua daim ntawv, qhov loj me, thaj chaw tshwj xeeb, thiab cov khoom tsim nyog los xyuas kom meej tias nws cov kev ua tau zoo thiab cov txheej txheem ua tau zoo hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, lossis cov khoom siv ua haujlwm.
Txheeb xyuas cov ntawv thov thiab xaiv cov qib purity uas tsim nyog.
Rau kev siv hluav taws xob (xws li, varistors, ceramic capacitors): Nws raug nquahu kom xaiv cov khoom uas muaj purity ntau dua lossis sib npaug rau 99.99% (5N) kom txo tau qhov cuam tshuam ntawm impurities ntawm dielectric zog thiab cov yam ntxwv ntawm kev laus.
Rau catalysis lossis iav xim: 99.0%–99.5% purity tuaj yeem siv tau, uas yog tus nqi ntau dua - siv tau thiab ua tau raws li qhov yuav tsum tau ua.
Ua tib zoo saib xyuas cov ntsiab lus tsis huv hauv daim ntawv ntsuam xyuas, tshwj xeeb tshaj yog hlau (Fe), chlorine (Cl⁻), sulfates, thiab lwm yam, vim tias cov no yuav cuam tshuam rau tus cwj pwm sintering thiab hluav taws xob ntawm cov khoom.
Thaum siv high - qhov kub thiab txias ib puag ncig, ua tib zoo mloog rau crystal stability.
Rau cov ntawv thov nyob rau hauv siab - kub khoom- xeev electrolytes lossis oxygen sensors, cov khoom uas tuaj yeem ua kom ruaj khov lossis txhawb cov δ-Bi₂O₃ theem yuav tsum tau ua ntej vim lawv cov pa oxygen ion siab.
Rau cov ntaub ntawv siv nyob rau hauv chav tsev kub (xws li pigments thiab additives), -Bi₂O₃ raws li lub ntsiab theem yog txaus kom tsis txhob muaj kev hloov pauv ntawm kev ua tau zoo los ntawm kev hloov ntawm theem siab ntawm - theem kub thaum txias.
Thov XRD qauv los ntawm tus neeg muag khoom kom paub meej tias hom siv lead ua theem tseem ceeb thiab muaj cov theem impurity.
Tswj particle loj thiab tej thaj chaw saum npoo kom optimize txheej txheem kev ua tau zoo:
Nano- loj bismuth trioxide (particle loj<100 nm) has a large specific surface area and high reactivity, making it suitable for catalyst supports or high-performance ceramic powders.
Micron- cov khoom loj (1-10 μm) muaj cov dej ntws zoo thiab tsim nyog rau cov txheej txheem kev lag luam xws li nias qhuav.
Nws raug nquahu kom xaiv qhov tsim nyog particle loj faib raws li cov txheej txheem tom ntej (piv txwv li, pob milling, txau, ntsiav tshuaj), thiab yuav tsum muaj daim ntawv qhia txog qhov loj me me ntawm laser.
