Cov 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 xyaw nrog cov tshuaj fluoride, nws tseem siv rau hauv cov siv lead ua cov fluoride ion-cov hluav taws xob xaiv.

Nws yog siv nyob rau hauv phosphor cov ntaub ntawv rau teeb pom kev zoo thiab tso saib thev naus laus zis, feem ntau ua ke nrog lwm cov hauv ntiaj teb tsawg.
