Cerium carbonate inorganic compound inogadzirwa nekuita cerium oxide ine carbonate. Iine kugadzikana kwakanaka uye kusagadzikana kwemakemikari uye inoshandiswa zvakanyanya muzvikamu zvakasiyana-siyana senge simba renyukireya, catalysts, pigment, girazi, nezvimwe. Zvinoenderana nedata remasangano ekutsvagisa misika, musika wepasi rose wecerium carbonate wakasvika madhora mazana maviri nemazana mana emadhora muna 2019 uye unotarisirwa kusvika. $3.4 bhiriyoni panosvika 2024. Pane nzira nhatu dzekutanga dzekugadzira cerium carbonate: makemikari, muviri, uye zvipenyu. Pakati penzira idzi, nzira yemakemikari inonyanya kushandiswa nekuda kwekuderera kwayo mari yekugadzira; zvisinei, zvinounzawo akakosha kusvibiswa kwezvakatipoteredza matambudziko. Iyo cerium carbonate indasitiri inoratidza yakakura budiriro tarisiro uye inogona asi inofanirwa kutarisana nekufambira mberi kwetekinoroji uye matambudziko ekuchengetedza kwezvakatipoteredza. UrbanMines Tech. Co., Ltd., bhizinesi rinotungamira muChina rinonyanya kutsvagisa nekusimudzira pamwe nekugadzira & kutengesa kwezvigadzirwa zvecerium carbonate ine chinangwa chekusimudzira kukura kweindasitiri kuburikidza nekukoshesa kwakangwara kwemaitiro ekuchengetedza kwezvakatipoteredza uku uchiita matanho ehungwaru. Chikwata cheUrbanMines 'R&D chakanyora chinyorwa ichi kupindura mibvunzo yemutengi wedu nezvazvinonetsa.
1.Chii chinonzi cerium carbonate chinoshandiswa? Ndeapi mashandisirwo ecerium carbonate?
Cerium carbonate musanganiswa unoumbwa necerium uye carbonate, unonyanya kushandiswa muzvinhu zvinokonzeresa, zvinhu zvinovheneka, zvinhu zvekupelisha, uye makemikari reagents. Nzvimbo dzayo dzekushandisa dzinosanganisira:
(1) Rare Earth luminescent materials: High-purity cerium carbonate inoshanda sechinhu chakakosha pakugadzira zvinhu zvisingawanzo kugadzirwa pasi pevhu. Izvi zvinhu zvinopenya zvinowana kushandiswa kwakakura mukuvheneka, kuratidza, uye mamwe minda, zvichipa rutsigiro rwakakosha kufambisira mberi kweindasitiri yemazuva ano yemagetsi.
(2) Motary engine exhaust purifiers: Cerium carbonate inoshandiswa mukugadzira mota exhaust yekuchenesa macatalysts ayo anoderedza zvinobuda zvinosvibisa kubva pamagetsi emotokari uye anoita basa rakakosha mukuvandudza kunaka kwemhepo.
(3) Zvishandiso zvekunatsa: Nekuita sechinhu chinowedzera mumakomisheni ekupukuta, cerium carbonate inowedzera kupenya uye kutsvedzerera kwezvinhu zvakasiyana-siyana.
(4) Mapurasitiki einjiniya ane mavara: Kana akashandiswa semumiriri wemavara, cerium carbonate inopa mavara chaiwo uye zvivakwa kumapurasitiki einjiniya.
(5) Kemikari Catalysts: Cerium carbonate inowana kushandiswa kwakasiyana-siyana sekemikari inogadzirisa nekusimudzira basa rinokonzera uye kusarudza apo ichikurudzira kushandiswa kwemakemikari.
(6) Kemikari reagents uye kushandiswa kwezvokurapa: Pamusoro pekushandiswa kwayo semakemikari reagent, cerium carbonate yakaratidza kukosha kwayo mune zvekurapa zvakadai sekupisa maronda.
(7) Cemented carbide additives: Kuwedzerwa kwecerium carbonate kune cemented carbide alloys inovandudza kuoma kwavo uye kupfeka kugona kwekudzivirira.
(8) Ceramic Indasitiri: Indasitiri yeceramic inoshandisa cerium carbonate sechinhu chinowedzera kuwedzera maitiro ekuita uye kutaridzika hunhu hweceramics.
Muchidimbu, nekuda kwezvivakwa zvayo zvakasiyana uye huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana siyana, cerium carbonates inotamba indispe.
2. Ndeupi ruvara rwecerium carbonate?
Rudzi rwecerium carbonate rwakachena, asi kuchena kwayo kunogona kukanganisa zvishoma ruvara, zvichiita kuti iite yellowish tint.
3. Ndeapi matatu anowanzo shandiswa ecerium?
Cerium ine matatu akajairika application:
(1) Inoshandiswa sechinhu chinokonzeresa mumotokari exhaust yekuchenesa zvinokonzeresa kuchengetedza okisijeni kuchengetedza basa, kusimudzira mashandiro anoita catalyst, uye kuderedza kushandiswa kwesimbi dzinokosha. Iyi catalyst yakagamuchirwa zvakanyanya mumotokari, zvichidzikamisa kusvibiswa kubva kumhepo yemotokari kuenda kunharaunda.
(2) Inoshanda sechinhu chinowedzera mugirazi yemaziso kutora ultraviolet uye infrared mwaranzi. Inowana kushandiswa kwakawanda mugirazi remotokari, ichipa dziviriro kubva kune UV mwaranzi uye kudzikisira tembiricha yemukati yemotokari, nekudaro ichichengetedza magetsi kune zvinangwa zvemhepo. Kubva 1997, cerium oxide yakaverengerwa mugirazi dzese dzemotokari dzeJapan uye inoshandiswa zvakanyanya muUnited States.
(3) Cerium inogona kuwedzerwa sechinhu chinowedzera kune NdFeB chisingaperi magineti zvinhu kusimudzira yavo magineti zvimiro uye kugadzikana. Zvishandiso izvi zvinoshandiswa zvakanyanya mumagetsi nemuchina wemagetsi senge mota nemajenareta, kuvandudza kugona kwemidziyo uye kuita.
4. Cerium inoita sei kumuviri?
Migumisiro yecerium pamuviri inonyanya kusanganisira hepatotoxicity uye osteotoxicity, pamwe chete nemigumisiro inogona kuitika pane optic nerve system. Cerium nemakomponi ayo zvinokanganisa epidermis yemunhu uye optic nerve system, uye kunyange kufema kushoma kunoisa njodzi yekuremara kana mamiriro ezvinhu anotyisidzira hupenyu. Cerium oxide ine chepfu kumuviri wemunhu, ichikonzera kukuvadza kuchiropa nemapfupa. Muhupenyu hwezuva nezuva, zvakakosha kutora matanho ekuzvidzivirira uye kudzivirira kufemesa makemikari.
Kunyanya, cerium oxide inogona kuderedza prothrombin yemukati ichiita kuti isashande; inhibit thrombin chizvarwa; precipitate fibrinogen; uye catalyze phosphate compound decomposition. Kugara kwenguva refu kune zvinhu zvine zvakawandisa zvisingawanzo pasi pasi zvinogona kukonzera kukuvara kwehepatic uye skeletal.
Pamusoro pezvo, poda yekupukuta ine cerium oxide kana zvimwe zvinhu zvinogona kupinda zvakananga mumapapu kuburikidza nekufema turakiti inhalation inotungamira kumapapu deposition inogona kukonzera silicosis. Kunyange zvazvo radioactive cerium ine mwero wakaderera wekunyura mumuviri, vacheche vane chikamu chakakwirira che144Ce kunyura mumaturakiti avo emudumbu. Radioactive cerium inonyanya kuunganidza muchiropa nemapfupa nekufamba kwenguva.
5. Iscerium carbonateinonyungudika mumvura?
Cerium carbonate hainyungudike mumvura asi inonyungudika muine acidic solution. Ikomboni yakagadzikana isingachinji kana yaiswa kumhepo asi inoshanduka dema pasi pechiedza che ultraviolet.
6.Is cerium yakaoma kana kuti yakapfava?
Cerium isimbi yakapfava, chena-chena isingawanzo shongedzerwa nemakemikari epamusoro uye chimiro chinogoneka chinogona kutemwa nebanga.
Zvinhu zvemuviri zvecerium zvinotsigirawo hunyoro hwayo. Cerium ine nzvimbo yekunyunguduka inosvika 795 ° C, nzvimbo yekuvira inosvika 3443 ° C, uye density ye6.67 g/mL. Pamusoro pezvo, inopinda shanduko yemavara kana yaiswa mumhepo. Izvi zvinoratidza kuti cerium isimbi yakapfava uye ine ductile.

Cerium inokwanisa kuita oxidizing mvura nekuda kwemakemikari ayo reactivity. Inoita zvishoma nezvishoma nemvura inotonhora uye nokukurumidza nemvura inopisa, zvichiita kuti pave nekugadzirwa kwecerium hydroxide uye hydrogen gasi. Mwero wekuita uku unowedzera mumvura inopisa kana ichienzaniswa nemvura inotonhora.
8. Ko cerium haiwanzoitiki here?
Hongu, cerium inoonekwa sechinhu chisingawanikwe sezvo ichiumba ingangoita 0.0046% yepasi, ichiita kuti ive imwe yezvakawanda kwazvo pakati pezvisingawanzo zvinhu zvepasi.
9. Cerium imvura yakasimba here kana gasi?
Cerium iripo seyakasimba pakamuri tembiricha uye kumanikidza mamiriro. Inoratidzika sesirivha-grey reactive metal ine ductility uye yakapfava kupfuura iron. Kunyangwe ichigona kushandurwa kuita mvura pasi pemamiriro ekupisa, panguva yakajairika (tembiricha yekamuri uye kumanikidzwa), inoramba iri muchimiro chayo chakasimba nekuda kwekunyungudika kwayo kwe795 ° C uye kuvira kwe3443 ° C.
10. Cerium inoita sei?
Cerium inoratidzira kutaridzika kwesimbi-grey reactive simbi yeboka rezvisingawanzo pasi zvinhu (REEs). Chiratidzo chayo chemakemikari ndiCe apo nhamba yeatomiki iri 58. Inobata mutsauko wekuve imwe yeREEs yakawanda yakawanda.Ceriu powder ine high reactivity kumhepo inokonzera kupisa kwepamuviri, uye inonyunguduka nyore muasidhi. Inoshanda seyakanakisa yekudzikisa mumiririri inonyanya kushandiswa kugadzira alloy.
Zvinhu zvepanyama zvinosanganisira: density ranges kubva ku6.7-6.9 zvichienderana nekristal structure; nzvimbo yekunyunguduka inomira pa799 ℃ uku ichifashaira ichisvika ku3426 ℃. Zita rekuti "cerium" rinobva pashoko reChirungu "Ceres", iro rinoreva asteroid. Izvo zvikamu zvemukati mukati mePasi pevhu zvinosvika ku0.0046%, zvichiita kuti ive yakanyanya kuwanda pakati pemaREE.
Ceriu inonyanya kuitika mumonazite, bastnaesite, uye fission zvigadzirwa zvakatorwa kubva uranium-thorium plutonium. Muindasitiri, inowana mashandisirwo akakura senge alloy kugadzira catalyst kushandiswa.
