Lanthanum oxide (inozivikanwawo se lanthana) ikemikari ine fomula La2O3. Iyo isingawanzo pasi oxide uye chena yakasimba zvinhu zvine cubic crystal chimiro. Lanthanum oxide ndeyepamusoro-tembiricha refractory zvinhu uye inoshandiswa mumhando dzakasiyana siyana nekuda kwekugadzikana kwayo kwemakemikari uye kusagadzikana kwekuora. Inoshandiswa sechinhu chekugadzira phosphors kuti ishandiswe mumachubhu e-cathode ray uye marambi efluorescent, senge dopant mune semiconductor zvishandiso, uye sechinhu chinokonzeresa. Inoshandiswawo mukugadzirwa kweceramics uye setracer mukutsvagisa biological uye kemikari.
Lanthanum Oxide, inonziwo Lanthana, kuchena kwakanyanya Lanthanum Oxide (99.99% kusvika 99.999%) inoshandiswa mukugadzira magirazi akakosha ekuvandudza alkali kuramba kwegirazi, uye inoshandiswa muLa-Ce-Tb phosphors yemarambi efluorescent uye kugadzira yakakosha yekuona. magirazi, akadai segirazi rinotora infrared, pamwe chete nekamera uye telescope lenses, Low giredhi yeLanthanum Oxide inoshandiswa zvakanyanya mumakeramiki uye FCC catalyst, uyewo seyakasvibirira yeLanthanum Metal production; Lanthanum Oxide inoshandiswawo sekuwedzera kwezviyo munguva yemvura yeSilicon Nitride uye Zirconium Diboride.
