Ib qho kev npaj ntawm praseodymium daj

Kev npaj ntawm praseodymium daj khoom muaj xws li: electrodeposited zirconia hais yog hauv av rau hauv cov hmoov nrog particle loj ntawm 3 ~ 5 tom qab homogenization. Cov nplaum nplaum nplaum nrog particle inch ntawm 1-1.5 tau los ntawm kev sib xyaw ntawm lithium sodium thiab mg-CA sib tov raws li 7: 4 qhov hnyav piv thiab tom qab ntawd los ntawm kub kub melting, dej quenching, dej ntxuav kom nruab nrab , ziab thiab sib tsoo. Lub siab kub melting kub yog 1300 degree . Cov zirconia hmoov yog tov nrog cov nplaum nplaum thiab tus nqi ntawm cov nplaum nplaum yog 0.05wt feem pua ​​​​ntawm tag nrho cov khoom sib tov. Cov hmoov zirconia tau kho ntawm 200 degree thiab 2MPa rau 10h kom tiav daim ntawv cog lus nrog cov nplaum nplaum. Kev hloov kho zirconia tau txais los ntawm kev txhim kho cov tshuaj tiv thaiv kev ua haujlwm ntawm electrofused zirconia. Lwm cov ntaub ntawv pabcuam ntawm cov hloov pauv electrofused zirconia thiab praseodymium daj cov ntaub ntawv tau muab sib xyaw ua ke, thiab calcined nyob rau hauv lub tais hauv qab oxidizing cua ntawm cua sov ntawm 160 degree / h. Thaum lub calcination kub mus txog 1000 degree, lub tshav kub preservation tau tuav rau 2 teev, thiab ces txias, sib tsoo, ntxuav thiab ziab kom tau praseodymium daj cov ntaub ntawv.
