Lanthanum Oxide,Molecular FormulaLa2o3, molecular uremu 325.8091. Inonyanya kushandiswa kuti igadzire chaiyo chaiyo yegirazi girazi uye Optical Fibers.
Chemical chivakwa
Zvishoma nezvishoma mumvura uye nyore nyore muAcids kuumba inoenderana munyu.
Kufumurwa nemhepo, zviri nyore kutora kabhoni dioxide uye mvura, zvishoma nezvishoma kutendeuka kuita lanthanum carbonate.
KupisaLanthanum Oxideinosanganisa nemvura kuti isunungure huwandu hukuru hwekupisa.
chivakwa chemuviri
Chitarisiko uye Zvivakwa: White Solid Powder.

Nzira yekugadzira
1. Iyo yakabikwa yeiyo nzira yekubvisa chikamu chevhu chisingawanzoitika mushure mekubvisa cerium yekubvisa, iyo ine makore makumi mashanu neshanu Yakatemerwa mu σ a a asotar naPasi Pasi Pasi Pasi pe330 Mhinduro yakasara ine lanthanum yakarongedzwa neAmmonia, yakagadzirirwa ne oxalic acid, uye yakabva yatendeuka uye yakatsvaira kuti awane chigadzirwa chakapedza cheLanthhanum Oxide. Kubviswa kubva kuna Lanthanu Phsphato Cerium Ore kana kugadzirira nekupisa lanthanum kabhoni kana nitrate. Inogona zvakare kuwanikwa nekudziya uye kuora oxalate yeLanthanamu.
2. Isa La (OH) 3 mune platinamu inowanzoitika, yakaoma pa200 ℃, kupisa pa500 ℃, uye kuora pamusoro pe840
Application
Inonyanya kushandiswa kuti igadzire chaiyo chaiyo yegirazi girazi uye Optical Fibers. Zvakare inoshandiswa muindasitiri yemagetsi secramic capacitors uye piezoelectric ceramic yekuwedzera. Iyo inoshandiswawo seyakaisa zvinhu zvekugadzirwa kwe lanthanamu bate uye seyakajaira kupatsanurwa kwepeturu uye kunatswa.
Runyoro Izvo zvinoshandiswawo mukugadzira ceramic capacitors, piezoelectric ceramic dopants, uye X-ray luminescent zvinhu zvakadai seLanthanu Bromidepoda. Kubviswa kubva kuna Lanthanu phosphato cerium ore kana kuwanikwa nekupisa lanthanum kabhoni kana nithrate. Inogona zvakare kuwanikwa nekudziya uye kuora oxalate yeLanthanamu. Inoshandiswa seyakajairwa kuita zvakasiyana-siyana, sekuti sekatoni oxidation ye carbon monoxide kana yakadzvanywa necadrogenation yeCarbon monoxide kune methane a methane after naFedy nePilladium. Lanthanum oxide inipindirwa neLithium oxide kana Zirconia (1%) inogona kushandiswa kugadzira mafineti ekugadzirisa. Icho chinoshanda zvakanyanya kusarudza kune iyo oxidative coupling yeMethane kuburitsa Ethane ne etiylene. Inoshandiswa kuvandudza tembiricha kutsamira uye dielectric zvivakwa zveBarium Titanate (Batio3) uye Strontium Titanate (SRTIO3) Ferroelecture Stic Zvese Zvishandiso uye Magirazi Epical.
