Txawm hais tias zirconium tetrachloride tau pom muaj peev xwm zoo hauv kev tshawb fawb hauv chav kuaj, nws txoj kev lag luam tseem ntsib qee qhov teeb meem:
1. Txheej txheem maturity:Tam sim no, cov txheej txheem ntau lawm ntawm zirconium tetrachloride thiab nws cov derivatives tseem tsis tau paub meej, thiab kev ruaj ntseg thiab kev sib xws ntawm cov khoom loj loj tseem yuav tsum tau tshawb xyuas ntxiv.
2.Cov nqi tswj:Txawm hais tias tus nqi ntawm cov khoom siv raw khoom tsawg tsawg, hauv kev tsim khoom tiag tiag, cov nqi tsim nyog xws li cov txheej txheem synthesis thiab cov cuab yeej cuab tam yuav tsum tau xav txog.
Kev lees txais kev ua lag luam: Lithium hlau phosphate thiab ternary lithium twb tau nyob hauv kev lag luam loj. Raws li cov khoom siv tawm tshiab, zirconium tetrachloride yuav tsum tau ua kom pom qhov zoo txaus hauv kev ua haujlwm thiab tus nqi kom tau txais kev lees paub ntawm kev lag luam.
Yav tom ntej Outlook
Zirconium tetrachloride thiab nws cov derivatives muaj cov ntawv thov dav dav hauv cov roj teeb lithium. Nrog rau kev nce qib ntawm thev naus laus zis tas li, nws cov txheej txheem tsim khoom yuav tsum tau ua kom zoo dua ntxiv thiab tus nqi yuav maj mam txo. Nyob rau hauv lub neej yav tom ntej, zirconium tetrachloride yuav tsum ua kom tiav cov ntaub ntawv xws li lithium hlau phosphate thiab ternary lithium, thiab txawm ua tiav ib nrab hloov hauv qee qhov kev thov tshwj xeeb.
