Lanthanum oxide (nke a makwaara dị ka lanthana) bụ ngwakọta kemịkalụ nwere usoro La2O3. Ọ bụ ụwa oxide na-adịghị ahụkebe na ihe siri ike na-acha ọcha nwere usoro kristal cubic. Lanthanum oxide bụ ihe na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ ma na-eji ya eme ihe n'ọtụtụ ngwa n'ihi nkwụsi ike nke kemịkal ya dị mma na nkwụsị corrosion. A na-eji ya dị ka ihe eji eme phosphor maka iji ya na tubes ray cathode na oriọna fluorescent, dị ka dopant na ngwaọrụ semiconductor, yana dị ka ihe na-eme ka ọ dị elu.
