Daim Ntawv Thov:
Lanthhanum fluoride, yog tsuas yog thov hauv cov iav tshwj xeeb, kev kho dej thiab catalyst, thiab tseem yog cov khoom siv raw rau ua cov ntaub ntawv lanthhanum. Lanthhanum fluoride (LAF3) yog qhov tseem ceeb ntawm cov iav fluoride hnyav tau hu ua zblan. Cov iav no muaj cov kev hloov pauv zoo tshaj hauv cov ntau yam thiab yog li ntawd siv rau cov tshuab sib txuas lus fiber ntau. Cov tshuaj fluora yog siv hauv phosphor teeb txheej. Sib tov nrog cov tshuaj fluoride, nws tseem siv tau rau cov tshuaj fluoride Cov tshuaj fluorhale yog siv los ua cov tshuaj fluoride fiber ntau thiab tsis tshua muaj cov iav fiber ntau thiab tsis tshua muaj lub ntiaj teb infrared iav. Cov tshuaj fluorhathancum fluoride yog siv rau hauv kev tsim khoom Arc Teeb Carbon Electrodes nyob rau hauv teeb pom kev zoo. Lanthhanum fluoride siv hauv kev tsom xam tshuaj los tsim cov tshuaj fluoride ion thiab cov roj ntsha fluorodes.

Cov Qauv Hluav Taws Xob
1. Dutve Lanthhanb oxide hauv hydrochloric acid los ntawm kev siv tshuaj lom neeg thiab dilute mus rau 100-150g / l (xam raws li la2o3). Ua kom sov cov tshuaj rau 70-80 ℃, thiab tom qab ntawd precipitate nrog 48% hydrofluoric acid. Nag lossis daus ntxuav, lim, qhuav, crushed, thiab lub tshuab nqus dej kom qhuav kom tau txais cov tshuaj fluoride.
2. Qhov chaw LACL3 kev daws muaj cov kua roj hydrochloric acid nyob rau hauv ib qho platinum tais thiab ntxiv 40% hydrofluoric acid. Ncuav tawm cov kua ntau dhau thiab evaporate qhov chaw seem qhuav.
