I-hygroscopic kakhulu ngeelwimi ezininzi: LanthanOxid, Oxyde De Lanthane, Oxido De Lanthano Rare earth lanthanum oxide la2o3
I-Lanthanum oxide (eyaziwa ngokuba yi-lanthana) yikhemikhali yekhemikhali kunye ne-formula La2O3. I-oxide yomhlaba enqabileyo kunye nezinto ezimhlophe eziqinileyo kunye nesakhiwo se-cubic crystal. I-Lanthanum oxide yinto yokushisa ephezulu yokushisa kwaye isetyenziswe kwizicelo ezahlukeneyo ngenxa yokuzinza kwayo kweekhemikhali kunye nokuchasana nokubola. Isetyenziswe njengento yokwenza i-phosphors ukuba isetyenziswe kwiityhubhu ze-cathode ray kunye nezibane ze-fluorescent, njenge-dopant kwizixhobo ze-semiconductor, kunye ne-catalyst. Ikwasetyenziswa kwimveliso yeeseramics nanjengomkhondo kuphando lwebhayoloji kunye nemichiza.
ILanthanum Oxide, ekwabizwa ngokuba yiLanthana, ukucoceka okuphezulu kweLanthanum Oxide (99.99% ukuya kwi-99.999%) isetyenziswa ekwenzeni iiglasi ezikhethekileyo zokubona ukuphucula ukuxhathisa kwealkali yeglasi, kwaye isetyenziswa kwiLa-Ce-Tb phosphors kwizibane zefluorescent kunye nokwenza i-optical ekhethekileyo. iiglasi, ezifana neglasi efunxa i-infrared, kunye nekhamera kunye netelescope lens, Umgangatho ophantsi I-Lanthanum Oxide isetyenziswa ngokubanzi kwi-ceramics kunye ne-FCC catalyst, kwaye kwakhona njengento ekrwada yemveliso ye-Lanthanum Metal; ILanthanum Oxide ikwasetyenziswa njengokongeza ukutya okuziinkozo ngexesha lolwelo lweSilicon Nitride kunye neZirconium Diboride.
