Imvelaphi kunye nemeko ngokubanzi
Izinto ezinqabileyo zomhlabaNgaba umgangatho webhodi ye-IIB Scandium, Yttrium kunye ne-Lanthanum kwitheyibhile yamaxesha ngamaxesha. Kukho izinto ze-l7. Umhlaba onqabileyo unepropathi eyodwa yomzimba kunye neekhemikhali kwaye isetyenziswe ngokubanzi kumzi-mveliso, kwezolimo nakwamanye amasimi. Ukucoceka kweempuku zomhlaba ezinqabileyo zomhlaba zimisela ubume obukhethekileyo bezixhobo. Ukucoceka okwahlukileyo kwezixhobo zomhlaba ezinqabileyo kunokuvelisa izixhobo ze-ceramic, izixhobo zeFluorescent kunye neZondo ze-Elektroniki ngeemfuno zomsebenzi ezahlukeneyo. Okwangoku, ngokuphuhliswa kwetekhnoloji yokukhuthaza umhlaba onqabileyo, amagqabantshintshi acocekileyo asemhlabeni anqabileyo, kwaye ulungiselelo lwezinto ezinqabileyo zomhlaba ezinqabileyo ezibeka phambili iimfuno eziphezulu zomhlaba onqabileyo. I-Cerium yequla iluluhlu olubanzi lokusetyenziswa, kwaye iziphumo zazo kwizicelo ezininzi zinxulumene nokucoceka, iipropathi zomzimba kunye nomxholo ongafanelekanga. Ukuhanjiswa kwezinto zomhlaba ezinqabileyo, iiakhawunti ze-cirium malunga ne-50% yokufumana umhlaba onqabileyo. Ngokwanda kokusetyenziswa kwesicelo esiphezulu se-rimerium ephezulu, imfuneko ye-S-rare yomhlaba onqabileyo ye-cerium iphezulu kwaye iphezulu.I-cerium oxideNgaba i-ceric oxide, inombolo ye-CAS yi-1306-38, ifomula yemolekyuli yi-CEO2, ubunzima bemolekyuli: 172.11; I-Cerium Oxide yeyona nto inqwenelekayo ye-oxial enqabileyo yomhlaba. Yinto etyheli etyheli eqinileyo kubushushu begumbi kwaye iba ngumnyama xa ishushu. I-Cerium Oxide isetyenziswe ngokubanzi kwizixhobo ze-luminescece, i-catalysts, ipowder yokuphosa, i-UV ikhusela kunye neminye imiba ethile ngenxa yokusebenza kwayo ngokugqibeleleyo. Kwiminyaka yakutshanje, ivuse umdla wabaphandi abaninzi. Ukulungiswa kunye nokusebenza kweCerium Oxide kube yi-hotspot yophando kwiminyaka yakutshanje.
Inkqubo yemveliso
Indlela yoku-1: Ukuvuselela kubushushu begumbi, yongeza isisombululo seSodium hydroxide ye-5.0mol / l kwisisombululo se-cerium ye-cerium / l kwixabiso le-bilmol / l, lungisa ixabiso le-PH libe likhulu kune-10, kwaye intsingiselo ye-PH yenzeka. I-sediment yatyhulwa, ihlanjwe izihlandlo ezininzi ngamanzi e-deoried, emva koko yomiswe kwi-90 ℃ i-oven iiyure ezingama-24. Emva kokugaya kunye nokucoca ubungakanani (ubungakanani be-particle i-0.1mm), i-cerium oxide ifunyenwe kwaye ibekwe kwindawo eyomileyo yogcino. Indlela yesi-2: Ukuthatha i-cirium chloride okanye i-cierium ye-pirium njengezinto eziluhlaza, ukulungisa ixabiso le-amomonium, emva koko ivuthiwe kwi-cerium i-900 ~ ℃. I-Cerium Oxide inokufunyanwa ngokufudumeza umxube we-cerium oxide kunye ne-carbon powder nge-1250 ℃ kwimo yekhabhoni yekharbon.
Isicelo
I-Cerium Oxide isetyenziselwa ukongezwa kwemveliso yeglasi, izixhobo zokugaya zeglasi zeglasi, kwaye zandisiwe kwiglasi yokugaya, iilebhu ze-binescope, iglasi ye-wire ye-iltraviolet kunye ne-wire ye-iltraviolet kunye ne-wire ye-iltraviolet kunye ne. Ikwasetyenziswa njenge-anti-umzkisi we-Wenglass Lens, kwaye i-cerium isetyenziselwa ukwenza i-cerium ye-titanium ityheli ukwenza i-tyheli yeglasi. Umphambili onqabileyo we-oxidation up of ifuthe elithile kwi-crystalization kunye neepropathi ze-ceramic yeglasi kwi-cao-Mgo-Ai23-System System. Iziphumo zophando zibonisa ukuba ukongezwa komphambili we-oxidation ofanelekileyo kuyanceda ukuphucula isiphumo solwelo kwiglasi, ukuphelisa ubume be-compact, kwaye baphucule izakhiwo ze-Alkali. Isixa esifanelekileyo songezelelo se-cerium oxide 1.5, xa isetyenziswa kwi-ceramic gyze kunye neshishini le-elektroniki njengePiezoelectric Pemiral Primic Pemiral. Ikwasetyenziswa ekwenzeni inzala yomsebenzi ophezulu, igesi ye-Lamp ye-I-Inclondescent, i-X-ray fluoorescent screen (ikakhulu isetyenziswa kwi-arhente yokuGqibela i-Lens). Umgubo onqabileyo we-cerium ye-cerium celing usetyenziswe ngokubanzi kwiikhamera, iileyikhasi zekhamera, ityhubhu yeTV, i-lens, njalo njalo. Ingasetyenziswa kwishishini leglasi. I-Cerium Oxide kunye neTitanium Dioxide inokusetyenziswa kunye ukwenza iglasi etyheli. I-Cerium Oxide yokufakelwa kweglasi inezibonelelo zomsebenzi ozinzileyo kwiqondo lokushisa eliphezulu, ixabiso eliphantsi kwaye akukho kukhanya kokukhanya okubonakalayo. Ukongeza, i-cerium oxide yongezwa kwiglasi esetyenzisiweyo kwizakhiwo nakwiimoto ukunciphisa ukuhanjiswa kwesibane se-ultraviolet. Ukuveliswa kwezixhobo ezinqabileyo zomhlaba ezinqabileyo, i-Cerium Oxide yongezwa njenge-phospile yombala onqabileyo weZibane ezisetyenziswayo kunye ne-phosphorives esetyenziswa kwizalathisi kunye nezixhobo zemitha I-Cerium Oxide ikwasisixhobo esiyilo sokulungiselela i-cerium yentsimbi. Ukongeza, kwizixhobo ze-semicondcuctor, i-pigments ephezulu-ephezulu kunye ne-pigritifizer yeglasi yeGlasi, i-AutoMotie i-AutoMotie isetyenzisiwe ngokubanzi. I-Catalyst ye-AutoMonjile yokucoca i-AutoMonjile iqokelelwe ikakhulu ye-houram ye-ceram Ukuthoba okwenzayo kubandakanya indawo enkulu ye-gamma-triogide, inani elifanelekileyo lee-oxidel elizinzayo kwindawo engaphezulu, kunye nesinyithi esinomsebenzi onesitayile esikhutshelweyo. Ukuze unciphise i-PT ye-PT, i-RH Dosage, yonyusa umthamo we-PD, unciphise iindleko ze-catalyst ngaphandle kokunciphisa i-cataights ecocekileyo yemoto, esetyenziswayo i-PT esetyenziswayo. I-PD. Ukusebenza kwe-tenary ye-RH ternalyst, ngokufuthi indlela yokuntywila ngokupheleleyo yokongeza isixa esithile se-cerium oxide kunye ne-lanthanum oxide, oko kukwenza isiphumo esinqabileyo somhlaba. I-ternary yentsimbi exabisekileyo. Lanthanum oxide and cerium oxide were used as auxiliaries to improve the performance of ¦ A-Alumina supported noble metal catalysts. Ngokutsho koPhando, i-Catalytic yendlela ye-cerium oxide kunye ne-lanthanum oxide ikakhulu kukuphucula umsebenzi obonakalayo wokudibana, ngokuzenzekelayo ilungelelanise i-oir-ratiation kunye nekatalisis, kwaye iphucule ubume bobuchwephesha bomphathi.
