Lanthanum oxide waa walax kiimiko ah, qaacidadeeda Molecular waa La2O3. Waxoogaa ku milmay biyaha, si fudud ugu milmi kara aashitada, fududahay in la nuugo kaarboon laba ogsaydh iyo biyaha marka hawada la soo gaadho, inta badan loo isticmaalo soo saarista muraayadda indhaha ee saxda ah iyo fiber Optical. Sifooyinkeeda kiimikaad ayaa waxyar ku milmay biyaha oo si fudud ugu milmay asiidhyada, taas oo keenta samaynta milix u dhigma. Marka lagu soo bandhigo hawada, way fududahay in la nuugo kaarboon laba ogsaydh iyo biyo, oo si tartiib tartiib ah u noqda Lanthanum carbonate. Lanthanum oksaydhkii gubtay wuxuu ku daraa biyo si uu u sii daayo kulayl badan.
Caadi ahaan, alaabooyinka waxaa lagu daraa inhibitors polymerization. Ku kaydi bakhaar qabow oo hawo leh. Ka fogow dhimbilaha iyo ilaha kulaylka. Heerkulka bakhaarka waa in aanu dhaafin 30 ℃. Baakadu waxay u baahan tahay xidhid, waana in aanay hawada la gelin. Waa in si gooni ah loo kaydiyaa oksijiinta, acids, alkalis, iwm oo aan lagu qasin kaydinta. Isticmaalka nalalka aan qarxin iyo tas-hiilaadka hawo-siinta. Mamnuuc isticmaalka qalabka farsamada iyo qalabka u nugul dhinbiilyada. Aagga kaydinta waa in lagu qalabeeyaa qalabka wax ka qabashada xaaladaha degdegga ah ee daadinta iyo alaabta kaydinta ku habboon.
Lanthanum oxide waxaa inta badan loo isticmaalaa in lagu soo saaro muraayadaha indhaha ee saxda ah iyo fiber indhaha. Waxa kale oo loo isticmaalaa warshadaha elektiroonigga ah sida capacitor dhoobada iyo isku dhejinta dhoobada piezoelectric. Waxa kale oo loo isticmaalaa sida walxo ceeriin ah diyaarinta lanthanum borate iyo kicinta kala soocidda batroolka iyo sifaynta
Lanthanum oxide waa unug aan organic ahayn oo leh qaacidada kiimikada La2O3, taas oo ah budo cad. Ku milmay aashitada, ethanol, ammonium chloride, oo aan lagu milmi karin biyaha iyo ketone. Naadirka dhulka lanthanum oxide ayaa si weyn loo isticmaalaa, gaar ahaan muraayadaha, ceramics, electronics iyo beeraha kale ayaa door muhiim ah ka ciyaara.
Isticmaalka: Inta badan waxaa loo isticmaalaa soo saarista muraayadaha indhaha ee saxda ah, fiber indhaha. Sidoo kale loo isticmaalo warshadaha elektiroonigga ah sida capacitors dhoobada, wakiilka dhoobada piezoelectric. Waxa kale oo loo isticmaalaa sida walxo ceeriin ah oo loogu talagalay diyaarinta lanthanum boride, iyo kicinta kala-soocidda batroolka iyo nadiifinta.
Codsiyada: Inta badan waxaa loo isticmaalaa soo saarista muraayadaha indhaha ee saxda ah ee gaarka ah, guddiga sare ee fiber indhaha, oo ku habboon kamaradaha, kamaradaha, muraayadaha mikroskoob iyo prisms qalab horumarsan, iwm. Waxa kale oo loo isticmaalaa soo saarista capacitors dhoobada, dhoobada piezoelectric dopants iyo qalabka luminescent raajada sida budada lanthanum oxybromide. Waxaa laga soo saaraa macdanta lanthanum lanthanum ama waxaa lagu helaa gubasho lanthanum carbonate ama lanthanum nitrate. Waxa kale oo lagu heli karaa burburka kulaylka ee lanthanum oxalate. Waxa loo istcimaalaa kicinta falcelino kala duwan, sida kicinta falcelinta oksaydhka ee karbon monoxide marka lagu daro cadmium oxide, iyo kicinta hydrogenation-ka carbon monoxide si ay u samayso methane marka lagu daro palladium. Lanthanum oxide oo uu ku jiro lithium oxide ama zirconium oxide (1%) ayaa loo isticmaali karaa samaynta birlabyada ferrite. Waa soo-dooriye wax-ku-ool ah oo wax-ku-ool ah oo isku-xidhka oksaydhka ee methane ilaa ethane iyo ethylene. Waxaa loo isticmaalaa in lagu wanaajiyo ku tiirsanaanta heerkulka iyo sifooyinka dielectric ee barium titanate (BaTiO3) iyo strontium titanate (SrTiO3) ferroelectrics, iyo in lagu soo saaro fiber optics iyo muraayadaha indhaha.
Waxa laga sameeyay alaabo gaar ah oo loo isticmaalo soo saarida muraayadda indhaha ee saxda ah, fibre-soo-celinta sare ee indhaha, oo ku habboon kamaradaha, kamarada, muraayadda mikroskoob iyo agabka indhaha ee horumarsan ee prism. Waxa kale oo loo isticmaalaa soo saarista capacitors dhoobada, piezoelectric ceramics dopants iyo raajada sii daaya bromine lanthanum oxide budada. Loo isticmaalo sidii kicin dad badan, hagaajinta barium titanate (BaTiO3), heerkulka strontium titanate (SrTiO3) ku tiirsanaanta guryaha ferroelectric iyo dielectric, iyo soo saarida fiber optics iyo muraayadaha indhaha.
