Kev piav qhia ntawm cov khoom

Lanthhanum sulfate hydrate muaj ntau cov khoom siv tshwj xeeb thiab tshuaj lom neeg uas ua rau nws muaj nuj nqis hauv ntau cov ntawv thov. Vim nws cov solubility siab hauv dej, lanthhanum sulfate nrhiav kev pab dav dav hauv cov txheej txheem dej. Nws ua raws li kev ua kom zoo ua ke thiab cov flocculant, pab hauv kev tshem tawm cov pa phem thiab raug tshem tawm ntawm cov dej. Tsis tas li ntawd, lanthhanum sulfate yog siv raws li kev catalyst nyob rau ntau yam tshuaj lom neeg, suav nrog synthesis ntawm cov tshuaj thiab cov organic sib xyaw.

Ntxiv mus, Lanthhanum sulfate yog qhov tseem ceeb ntawm kev tsim cov phosphors rau cov ntawv thov teeb pom kev zoo. Nws ua kom pom cov khoom zoo heev, ua rau nws haum rau cov roj fluorescent, cathode duab ntov kab (CRT), thiab lwm yam kev siv thev naus laus zis.

WASAXI tuam txhab (WNX) yog cov kws tshaj lij kev lag luam ntawm lub ntiaj teb tsis tshua muaj kev tshawb nrhiav thiab cog lus rau kev txhim kho thev naus laus zis. Peb lub tuam txhab npaj los tsim cov khoom lag luam zoo,wE tau tsim los ntawm cov sulfate sulfate ntev dua kaum xyoo nrog rau ntau lub tebchaws thiab cov cheeb tsam thiab kab ke thiab kev siv cov xwm txheej sib txawv.
