Ukusetyenziswa kweLanthanum oxide :
ILanthanum oxide, ekwabizwa ngokuba yiLanthana,ubunyulu obuphezulu beLanthanum oxide(99.99% ukuya kwi-99.999%) isetyenziselwa ukwenza iiglasi ezikhethekileyo zamehlo ukuphucula ukuxhathisa kwe-alkali yeglasi, kwaye isetyenziselwa i-phosphors ye-La-Ce-Tb kwizibane ze-fluorescent kunye nokwenza iiglasi ezikhethekileyo ze-optical, njengeglasi ye-infrared-absorbing, ngokunjalo. njengekhamera kunye neelensi zeteleskopu, Ibanga eliphantsi leLanthanum Oxide lisetyenziswa kakhulu kwi-ceramics kunye ne-FCC catalyst, kunye nezinto eziluhlaza kwimveliso ye-Lanthanum Metal;ILanthanum Oxide ikwasetyenziswa njengokongeza ukutya okuziinkozo ngexesha lolwelo lweSilicon Nitride kunye neZirconium Diboride.I-Lanthanum Oxide isetyenziselwa ukuvelisa i-lanthanum yensimbi kunye ne-lanthanum cerium metal, i-catalysts, izinto zokugcina i-hydrogen, izinto ezikhupha ukukhanya, izixhobo ze-elektroniki, njl.
