Maxaa Lanthanum Oxide loo isticmaalaa?
Sida curiyaha dhulka naadir ah, Lanthanum waxaa loo isticmaalaa in lagu sameeyo nalalka kaarboonka kuwaas oo loo isticmaalo warshadaha sawirka dhaqdhaqaaqa iftiinka istuudiyaha iyo nalalka mashruuca.Lanthanum oxidewaa in loo isticmaalo sahayda lanthanum. Lanthanum Oxide waxay ka heshay isticmaalka: muraayadaha indhaha, fosfooraska La-Ce-Tb ee fluorescent, kicinta FCC. Waxay ku habboon tahay codsiyada muraayadaha, indhaha iyo dhoobada, waxaana loo isticmaalaa qaar ka mid ah qalabka ferroelectric, waxayna quudin u tahay kiciyayaasha qaarkood, iyo isticmaalka kale.
