Cleachdadh Lanthanum Oxide:
Lanthanum oxide, ris an canar cuideachd Lanthana,àrd-ghlan Lanthanum oxide(99.99% gu 99.999%) air a chuir an sàs ann a bhith a’ dèanamh glainneachan optigeach sònraichte gus an aghaidh glainne alcali a leasachadh, agus air a chleachdadh ann an phosphors La-Ce-Tb airson lampaichean flùraiseach agus a’ dèanamh glainneachan optigeach sònraichte, leithid glainne infridhearg, cuideachd mar lionsan camara agus teileasgop, tha ìre ìosal de Lanthanum Oxide air a chleachdadh gu farsaing ann an stuthan ceirmeag agus catalyst FCC, agus cuideachd mar stuth amh airson cinneasachadh Lanthanum Metal;Tha Lanthanum Oxide cuideachd air a chleachdadh mar chur-ris fàs gràin aig àm sintering ìre liùlach de Silicon Nitride agus Zirconium Diboride.Tha Lanthanum Oxide air a chleachdadh gus meatailtean lanthanum agus lanthanum cerium meatailt, catalysts, stuthan stòraidh haidridean, stuthan sgaoileadh solais, co-phàirtean dealanach, msaa a dhèanamh cuideachd.
