Mokhoa oa maiketsetso
1. Hlakola lanthanum oxide ka hydrochloric acid ka mokhoa oa lik'hemik'hale 'me u hlapolle ho 100-150g / L (e baloang e le La2O3). Chesa tharollo ho 70-80 ℃, 'me u phomole ka 48% ea hydrofluoric acid. Pula ea hlatsuoa, e tlhotliloeng, e omisitsoe, e sithabelitsoe, 'me e felloa ke metsi 'meleng ho fumana lanthanum fluoride.
2. Beha tharollo ea LaCl3 e nang le hydrochloric acid ka sejana sa platinum 'me u kenye 40% ea hydrofluoric acid. Tšela mokelikeli o feteletseng 'me u mofale masala a omme.
