I-Lanthanum oxide,ifomula yamangqamuzanaLa2o3, isisindo molecular 325.8091. Isetshenziselwa ikakhulukazi ukukhiqiza ukululeka kwe-Optical Glass nemicu ye-Optical.
Impahla yamakhemikhali
Incibilika kancane emanzini futhi incibilike kalula kuma-acid ukwakha usawoti ohambelana nawo.
Kuvezwe emoyeni, kulula ukumunca i-carbon dioxide namanzi, kancane kancane kuguqulwe ku-lanthanum carbonate.
Ukushiswalanthanum oxideHlanganisa ngamanzi ukukhulula inani elikhulu lokushisa.
impahla yenyama
Ukubukeka nezakhiwo: Impuphu eqinile emhlophe.
Ubuningi: 6.51 g / ml ngo-25 ° C
Iphoyinti elincibilikayo: 2315 ° C, Iphuzu elibilayo: 4200 ° C
I-Solubinity: incibilika kuma-acid kanye ne-ammonium chloride, insoluble emanzini nama-ketones.
Indlela yokukhiqiza
1. Izinto ezingavuthiwe zendlela yokukhipha indawo eyinqayizivele yomhlaba i-nitrate hlaba ngemuva kokususwa kwe-cerium, okuqukethe cishe ama-50% la2o3, amanani we-116-7% PR6O5, ne-30% ND2O3. Ihlanganiswe ku-Σ I-Rare Earth Nitrate Solution ene-320-330g / l ye-RXOY yakhishwa futhi ihlukaniswe neminye imihlaba engapheli isebenzisa i-Phosylylyphosphon (P350), ohlelweni lwe-P350), ohlelweni lwe-P350) lwezigaba ezingama-35-38 zokukhishwa. Isixazululo esasele esiqukethe iLanthanum sasingathathi hlangothi ne-ammonia, sanembe nge-oxalia acid, bese sihlungwa futhi sishiswe ukuthola umkhiqizo oqediwe we-lanthanum oxide. Kukhishwe kusuka ku-lanthanum phosphate cerium ore noma elungiselelwe ngokushisa i-lanthanum carbonate noma i-nitrate. Ingatholakala futhi ngokushisa nokuvusa inkanuko ye-lanthanum.
2. Beka uLa (oh) 3 ku-platinam ekhanyayo, yomile ngo-200 ℃, shisa ngo-500 ℃, futhi ubole ngaphezulu kuka-840 ℃ ukuthola iLanthanum Oxide.
Isicelo
Isetshenziselwa ikakhulukazi ukukhiqiza ukululeka kwe-Optical Glass nemicu ye-Optical. Ibuye isetshenziswe embonini ye-elekthronikhi njenge-capacitors ye-ceramic kanye ne-piezoelectric ceramic izengezo. Iphinde isetshenziswe njengento eluhlaza yokukhiqizwa kweLanthanum Bouction futhi njenge-catalyst yokuhlukaniswa kukaphethiloli nokucwengeka.
Inkambu Yesicelo: Isetshenziselwa ikakhulukazi ukukhiqiza i-alloy ekhethekile ye-Optical Glass, i-High Deaptical Fiber Board, ilungele ukwenza amakhamera, amakhamera, ama-microscope lens, kanye nama-priscope amathuluzi aphezulu aphezulu. Iphinde isetshenziswe ekwenziweni kwama-capacitors we-ceramic, ama-pezoelectric ceramic dopants, kanye nezinto zokwakha ze-x-ray zifanaI-Lanthanum Bromidei-powder. Kukhishwe kusuka ku-lanthanum phosphate cerium ore noma etholwe ngokushiswa i-lanthanum carbonate noma i-nitrate. Ingatholakala futhi ngokushisa nokuvusa inkanuko ye-lanthanum. Kusetshenziswe njenge-catalyst yokusabela okuhlukahlukene, okufana ne-catalytic oxidation ye-carbon monoxide lapho idonswa yi-cadmium oxide, kanye ne-catalytic hydrogenation ye-carbon monoxide ku-methane lapho idonswa yi-palladium. ILanthanum oxide ingena ngaphakathi kwe-lithium oxide noma i-zirconia (1%) ingasetshenziswa ukwenza ama-ferrite magnets. Kuyinto ekhethekayo ekhethiwe ekuhlanganiseni ngokuhlanganiswa kwe-oxidative of Methane ukukhiqiza i-ethane ne-ethylene. Kusetshenziselwe ukuthuthukisa ukuncika kokushisa kanye ne-dielectric Properties ye-barium titanate (batio3) kanye ne-strontium) kanye ne-strtio3) Ferroelecctrics, kanye nokwenza amadivaysi e-fiber optic nezibuko ze-optical.
