I-Lanthanum oxide yikhemikhali, kwaye i-molecular formula yayo yiLa2O3. Inyibilika kancinci emanzini, inyibilika ngokulula kwiasidi, kulula ukufunxa ikharbon diokside kunye namanzi xa ityhilekile emoyeni, ikakhulu isetyenziselwa ukwenziwa kweglasi echanekileyo yokukhanya kunye nefayibha ye-Optical. Iimpawu zayo zeekhemikhali zinyibilika kancinane emanzini kwaye zinyibilika ngokulula kwiiasidi, okukhokelela ekubunjweni kweetyuwa ezihambelanayo. Ivezwe emoyeni, kulula ukufunxa i-carbon dioxide kunye namanzi, kwaye ngokuthe ngcembe ibe yiLanthanum carbonate. I-Lanthanum oxide etshisiweyo idibanisa namanzi ukukhulula ubushushu obuninzi.
Ngokuqhelekileyo, iimveliso zongezwa nge-polymerization inhibitors. Gcina kwindawo epholileyo nengena umoya. Zigcine kude neentlantsi kunye nemithombo yobushushu. Ubushushu bendawo yokugcina impahla akufunekanga budlule kwi-30 ℃. Ukupakishwa kufuna ukutywinwa kwaye akufuneki kudibane nomoya. Kufuneka igcinwe ngokwahlukileyo kwi-oxidants, i-acids, i-alkalis, njl. kwaye akufanele ixutywe ukugcina. Ukusebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya. Ukuthintela ukusetyenziswa kwezixhobo zoomatshini kunye nezixhobo ezithandwa ziintlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zokusabela ngokukhawuleza xa kuvuza kunye nezixhobo ezifanelekileyo zokugcina.

I-Lanthanum oxide efakwe nge-lithium oxide okanye i-zirconium oxide (1%) ingasetyenziselwa ukwenza imagnethi ye-ferrite. Yinto esebenzayo kakhulu ekhethiweyo yokudityaniswa kwe-oxidative ye-methane kwi-ethane kunye ne-ethylene. Isetyenziselwa ukuphucula ukuxhomekeka kobushushu kunye neempawu ze-dielectric ze-barium titanate (BaTiO3) kunye ne-strontium titanate (SrTiO3) i-ferroelectrics, kunye nokuvelisa i-fiber optics kunye neglasi ebonakalayo.
Yenziwe ngee-alloys ezikhethekileyo ezisetyenziselwa ukwenziwa kweglasi echanekileyo yeglasi, i-high refractive optical fiber, ifanelekile kwiikhamera, ikhamera, i-microscope lens kunye nezixhobo eziphambili ze-optical prism. Ikwasetyenziswa ekwenzeni i-ceramic capacitors, i-piezoelectric ceramics dopants kunye ne-X-ray ephumayo yebromine lanthanum oxide powder. Isetyenziswe njenge-catalyst yabaninzi, ekuphuculeni i-barium titanate (i-BaTiO3), i-strontium titanate yeqondo lokushisa (i-SrTiO3) ixhomekeke kwiipropati ze-ferroelectric kunye ne-dielectric, kunye nokuveliswa kwe-fiber optics kunye ne-glass optical.
