Kodi Lanthanum Oxide imagwiritsidwa ntchito bwanji?
Monga chinthu chosowa padziko lapansi, Lanthanum imagwiritsidwa ntchito popanga magetsi a carbon arc omwe amagwiritsidwa ntchito popanga zithunzi zoyenda pakuyatsa situdiyo ndi magetsi a projector.Lanthanum oxideiyenera kugwiritsidwa ntchito ngati chopereka cha lanthanum. Lanthanum Oxide imapeza ntchito mu: Magalasi owoneka, La-Ce-Tb phosphors a fulorosenti, zopangira za FCC. Ndi yoyenera kuyika magalasi, optic ndi ceramic, ndipo imagwiritsidwa ntchito muzinthu zina za ferroelectric, ndipo ndi chakudya chazothandizira zina, pakati pa ntchito zina.
