Kwiminyaka yakutshanje, ukusetyenziswa kwerejista ye-lanthenaide kwi-synthesi ye-organic sele kuphuhliswe ngokutsiba kunye nemida. Phakathi kwawo, uninzi lwe-regenanide Reagents lwafunyanwa lube ne-Catasisis ecacileyo kwimpendulo ye-carbon-carbon-carbon-carbon-carbon-carbon. Kwangelo xesha, uninzi lwe-regenide Reagents i-regedhed ifunyenwe ineempawu ezintle kwizinto eziphilayo ze-osidation kunye nokuncitshiswa kwezinto ezisebenzayo ukuguqula amaqela asebenzayo. Ukusetyenziswa komhlaba onqabileyo kukusetyenziswa kophando lwesayensi kunye neempawu zaseTshayina ezifunyenwe ngabasebenzi benzululwazi yaseTshayina kunye netekhnoloji emva kweminyaka yobugcisa, kwaye bakhuthazwe njengenyathelo elibalulekileyo lokwandisa imveliso yezolimo eTshayina. I-Carbonate yasemhlabeni inyibilika ngokulula kwi-acid ukwenza i-acid ye-acid kunye nekharbon diokside, enokuthi isetyenziswe ngokulula kwi-synthes ye-synthes kunye nezazisa ngaphandle kokungcola kwe-adionic. Umzekelo, inokusabela ngee-asidi eziqinileyo ezinjenge-nitric acid, i-hydrochloric acid, i-nitric acid, i-perchloric acid, kunye ne-sulfuric acid ukwenza iityuwa ezinyibilikayo. Yenza i-phosphoric acid kunye ne-hydrofluoric acid yokuguqula ibe kwi-Inforle yasemhlabeni phosphates kunye ne-fluors. Yenza i-acids ezininzi ze-orgads ukuba ibonise imilinganiselo ye-order edibanisileyo. Banokungagungqi zinyibilikisi okanye ii-anaons ezinzima, okanye iikhomputha ezingathathi cala zinqabileyo zibonisa ukuba kuxhomekeka kwixabiso lesisombululo. Kwelinye icala, umhlaba onqabileyo we-carbonate unokubekwa kwii-oxiles ezihambelana ngokuhambelana, ezinokusetyenziswa ngokuthe ngqo kumalungiselelo eento ezininzi ezinqabileyo zomhlaba ezinqabileyo. Okwangoku, ukuphuculwa konyaka kwi-Carbonate eChina kungaphezulu kwe-10,000 yeetoni, i-accounting yekota yonke yomhlaba onqabileyo idlala indima ebaluleke kakhulu kuphuhliso lomhlaba onqabileyo.
I-Cerbonate ye-Carbonate yimozulu ye-inorganic yefomula ye-C3CE26, ubunzima bemoya ye-460, i-SPDA ye-333.6ºc nge-79 mmhg, kunye ne-flash ye-169.8ºc. Ukuveliswa kwemveliso yehlabathi elinqabileyo, iCerium Carbonate sisixhobo esijikelezileyo sokulungiselela iimveliso ezahlukeneyo ze-ririum ezinjengeetyuwa ezahlukeneyo ze-cerium kunye ne-cerium oxide. Inoluhlu olubanzi lokusetyenziswa kwaye yimveliso ebalulekileyo yomhlaba onqabileyo. I-crystal ye-cerium ye-cerium ye-cerium inomgangatho ocacileyo we-lanthanite, kwaye ifoto yayo ye-SEM ibonisa ukuba ubume besisiseko se-crystal ye-cerium ye-cerium ye-cerbonter yi-flatse-njenge-flakes efana ne-flake, kwaye phantsi kwesenzo somatshini kulula ukuba siconjululwe kwizinto ezincinci. I-Cerbonate ye-Cerbonate iveliswe kwimveliso okwangoku ine-42-46% kuphela yomhlaba onqabileyo emva komile, enza imida ekusebenzeni kwemveliso yeCerium Carbonate.
Uhlobo lokusebenzisa amanzi aphantsi, umgangatho ophantsi, ukuvelisa i-Cerbonate evelisiweyo akufuneki ukuba yomiswe okanye yomiswe yi-Centrifugal, kwaye yonke inkqubo ilula kwaye ilula kwi-Cerium Carbonate iyonke yehlabathi liphela. Le nkqubo ilandelayo ithathelwe ingqalelo: Indlela yenqanaba ngalinye isetyenziselwa ukulungiselela i-Cerium Carbonate enexabiso elinzima lomhlaba onqabileyo, oko kukuthi, i-Cerium Sokoolt yongezwa kwi-Cerbonate ye-carium. Isixa se-Amonium Bicarbonate sihlengahlengiswa ukuze ixabiso le-PH litshintshelwe kwi-6.3 ku-6.5 ukuya kwi-6.5, kwaye amanqanaba ongezelelweyo afanelekile ukwenzela ukuba i-quend. Isisombululo se-cerium sokol sisisombululo esinye se-cerium ye-cierium chlorigh, isisombululo se-cerium ye-cerium ye-cerium ye-cerium ye-cerium okanye isisombululo se-cerium seitrate. Iqela le-R & D leTekhnoloji yase-Urbanines. CO.
I-Cerbonate yeCerbonate inokusetyenziselwa ukulungiselela i-cerium oxide, i-cerium diokside kunye nezinye i-nanomanzis. Izicelo kunye nemizekelo imi ngolu hlobo lulandelayo:

2. Ipeyinti yokugcina amandla e-Endothermic, ephawuleka kuloo nto isenziwa ngokuxuba i-filler kunye nempahla yokwenza ifilimu, kunye ne-50 ukuya kwi-35 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-8 ukuya kwi-Alumini. I-4 ukuya kwi-10 yeenxalenye ze-titanium oxide, iinxalenye ezi-4 ukuya kwezi-10 zeZinCide, i-5 ukuya kwi-5 ye-5 ukuya kwi-5 ye-5 ukuya kwi-5 ye-5 ukuya kwi-0.5 ye-0.5 ukuya kwi-0.01 ukuya kwi-1.5 yeenxalenye ze-chromium oxide. Inxalenye, i-0.01-1.5 Iinxalenye zeKaolin, i-0.01-1.5 Iinxalenye zezixhobo zomhlaba ezinqabileyo, i-0.8-5 ye-carbon emnyama, ubungakanani bezinto ezimbini ze-REAW yi-1-5 μm; Apho, izixhobo zomhlaba ezinqabileyo zibandakanya iinxalenye ze-0.01-1.5 ze-lanthanum carbonate 1.5 iinxalenye ze-ceseodymium ye-cirbodium 1.5 ukuya kwi-1,01 ukuya kwi-0.01 ukuya kwi-0.01 ukuya kwi-1.5 yeenxalenye ze-prometium. Isixhobo sokwakha ifilimu yi-potassium sodium carbonate; I-potassium sodium carbonate ixutywe nobunzima obufanayo we-potassium ye-carbonate kunye nesodium carbonate. Ubungakanani bomgangatho wokuxuba i-filler kunye nempahla yokwenza ifilimu yi-2,5: 7.5, 3.8: 6.2 okanye 4.8: 5.2. Ngaphaya koko, uhlobo lwendlela yokulungiselela yepeyinti yokugcina amandla epeyinti ibonakaliswa naleyo iquka la manyathelo alandelayo:
Inyathelo loku-1, ukulungiswa kwe-filler, kuqala ukubunzima ngama-20 ukuya kwi-8 ukuya kwi-8 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-4 ukuya kwi-5-5 ye-zincide ubunzima. , Iinxalenye ezi-1 ukuya kwezi-5 ze-magnesium oxide, i-5 ukuya kwi-5 ye-i-0.02 ukuya kwi-0.5 yeenxalenye ze-chromium enqabileyo, kunye ne-1.5 yeenxalenye ze-chromium, kunye ne-1,5 ukuya kwi-1,5 yeenxalenye ze-chbon emnyama, kwaye emva koko zidityaniswe kumxube ukufumana i-filler; Apho, izinto ezinqabileyo zomhlaba zibandakanya iinxalenye ze-0.01-1.5 ze-lanthanum carbonate, i-0.01-1.5 iinxalenye zeCrasehedymium Carbonate, i-0.01-1.5 yeenxalenye ze-prometium ye-prometium;
Inyathelo 2, ukulungiselela izinto zokwenza ifilimu, izixhobo zokwenza ifilimu yindawo ye-sodium polbonate; I-Wiclotium yokuqala ye-Potosbonate kunye ne-sodium carbonate ngokwahlukeneyo ngobunzima, emva koko uzidibanise ngokulinganayo ukufumana izinto zokwenza ifilimu; I-Sodium Potcesbonate i-carbonatium ye-slodium inobunzima obufanayo we-potasquyam ye-potasquate kunye ne-sodium bodium ixutywe;
Inyathelo 3, umyinge wokuxuba i-filler kunye nezinto zefilimu ngesisindo yi-2.5: 7.5: 6.2, kwaye umxube uxutywe ngokufanayo kwaye usasazekile ukufumana umxube;
Kwinyathelo 4, umxube yibhola-ye-Iball -0 iiyure, kwaye emva koko imveliso egqityiweyo ifunyenwe ngokudlula kwisikrini, kunye ne-mesh yescreen yi-1-5 μm.
3. Ukulungiswa kwe-iltrafine cerium oxide: usebenzisa i-hydium carbonate njengomntu ophambili, i-ultrafine cerium oxide i-3 μ ye-Perian ye-Pien engaphantsi kwe-3 μm ilungiselelwe ngokugaya ibhola ye-3. Iimveliso ezifunyenweyo zonke zinemigangatho ye-cubic fluorite. Njengoko ubushushu obungahlawulelwayo bunyuka, ubungakanani bemveliso yeemveliso buyancipha, ubungakanani bobungakanani besuntswana luba lumncinci kwaye i-crystallies inyuka. Nangona kunjalo, amandla okuphumeza kweeglasi ezintathu ezahlukeneyo zibonisa ixabiso eliphezulu phakathi kwe-900 ℃ kunye ne-1000 ℃. Ke ngoko, kukholelwa ukuba inqanaba lokukhupha iiglasi zomhlaba ngexesha lenkqubo yokuphola ichaphazeleke kakhulu kuluhlobo lwesuntswana, i-crystallity kunye nomsebenzi womphezulu womgubo oqingqiweyo.
