Maxaa loo isticmaalaa Lanthanum Oxide?
Iyada oo ah curiye dhul naadir ah, Lanthanum waxaa loo isticmaalaa in lagu sameeyo nalalka kaarboonka kuwaas oo loo isticmaalo warshadaha sawirrada dhaqdhaqaaqa ee nalalka istuudiyaha iyo nalalka projector-ka.Lanthanum Oxidewaa in loo isticmaalaa sidii sahay lanthanum ah. Lanthanum Oxide waxay isticmaashaa: Muraayadaha indhaha, fosfooraska La-Ce-Tb ee fluorescent-ka, kataliyayaasha FCC. Waxay ku habboon tahay codsiyada galaaska, indhaha iyo dhoobada, waxaana loo isticmaalaa qaar ka mid ah walxaha ferroelectric, waana quudin loogu talagalay kataliyeyaasha qaarkood, iyo isticmaal kale.
