He aha te mea e whakamahia ana e te waea o Lanthanum?
Ka rite ki te mea nui o te whenua, ka whakamahia a Lanthanum hei rama waro e whakamahia ana i roto i te umanga pikitia mo te ako me te rama rama.Lanhanum Onoko te whakamahi hei taonga mo Lanthanum. Ka kitea e Lanthanum Fomes i roto i: Nga karaihe Optical, La-Ce-TB Phosphors mo te Fracerescent, FCC Catalysts. He pai mo te karaihe, tono optic me te aukip, a ka whakamahia i roto i etahi taonga Ferroelectric, he kai mo etahi kaihokohoko, i waenga i etahi atu whakamahinga.
