Cerium oxyde, Inzira ya molekulari niCeO2, Igishinwa bita:Cerium (IV) oxyde, uburemere bwa molekile: 172.11500. Irashobora gukoreshwa nkibikoresho byo gusya, catalizator, umutwara wa catalizator (umufasha), imashini ya ultraviolet, moteri ya lisansi electrolyte, imashini itwara ibinyabiziga, amashanyarazi, nibindi.
Umutungo wimiti
Ku bushyuhe bwa 2000 ℃ hamwe n’umuvuduko wa MPa 15, okiside ya Cerium (III) irashobora kuboneka hakoreshejwe hydrogène igabanya okiside ya cerium. Iyo ubushyuhe ari ubuntu kuri 2000 and, naho umuvuduko ukaba kuri MPa 5, oxyde ya cerium iba umuhondo gake, umutuku muto, nijimye.
Umutungo wumubiri
Ibicuruzwa byera ni ifu iremereye cyane cyangwa kirisiti ya cubic, mugihe ibicuruzwa byanduye ari umuhondo woroshye cyangwa se umutuku wijimye wijimye (bitewe nubunini bwa lanthanum, praseodymium, nibindi).
Ubucucike 7.13g / cm3, gushonga 2397 ℃, ingingo itetse 3500 ℃ ..
Kudashonga mumazi na alkali, gushonga gato muri aside.
Uburozi, ikigereranyo cyica Mediyani (imbeba, umunwa) ni 1g / kg.
Uburyo bwo gukora
Uburyo bwo gukora bwa cerium oxyde ahanini ni imvura igwa kuri aside ya oxyde, ni ukuvuga gufata cerium chloride cyangwa Cerium nitrate yumuti nkibikoresho fatizo, guhindura agaciro ka Ph kuri 2 hamwe na acide oxyde, ukongeramo ammonia kugirango ugabanye Cerium oxyde, gushyushya, gukura, gutandukanya, gukaraba , gukama kuri 110 ℃, no gutwika kuri 900 ~ 1000 ℃ kugirango ube cerium oxyde.
CeCl2 + H2C2O4 + 2NH4OH → CeC2O4 + 2H2O + 2NH4Cl
Gusaba
Oxidizing. Catalizator ya reaction ya Organic. Koresha icyuma kidasanzwe cyicyitegererezo cyicyitegererezo cyo gusesengura ibyuma. Isesengura rya titre ya Redox. Ikirahure gifite ibara. Ikirahuri enamel izuba. Ubushyuhe budashobora gushyuha.
Ikoreshwa nk'inyongera mu nganda y'ibirahure, nk'ibikoresho byo gusya ibirahuri, kandi nanone nk'umuti urwanya UV mu kwisiga. Kugeza ubu, yaguwe no gusya ibirahuri, lensike optique, hamwe nigituba cy’amashusho, bigira uruhare mu gushushanya, gusobanura, kwinjiza UV kwikirahure, no kwinjiza imirongo ya elegitoroniki.
Ingaruka zidasanzwe zo gutaka isi
Ifu idakunze kuboneka ifu ifite ibyiza byo kwihuta cyane, gukora neza, no kuramba kuramba. Ugereranije nifu ya porojeri gakondo - ifu yumutuku wicyuma, ntabwo yangiza ibidukikije kandi byoroshye kuvana mubintu bifatanye. Kuringaniza lens hamwe nifu ya cerium oxyde ifata ifata umunota umwe kugirango irangire, mugihe ukoresheje ifu ya okiside ya piside ifata iminota 30-60. Kubwibyo, ifu idasanzwe yo gusya ifu ifite ibyiza bya dosiye nkeya, kwihuta cyane, hamwe no gukora neza. Kandi irashobora guhindura ubuziranenge bwibidukikije hamwe nibikorwa bikora. Mubisanzwe, ifu yubutaka idasanzwe yikirahure ikoresha cyane cyane cerium ikungahaye kuri okiside. Impamvu itera cerium oxyde ningirakamaro cyane yo gusya ni ukubera ko icyarimwe ishobora guhanagura ikirahuri ikoresheje kubora imiti no guteranya imashini. Ifu idasanzwe ya cerium polishing ifu ikoreshwa cyane mugusya kamera, lens kamera, imiyoboro ya tereviziyo, ibirahure, nibindi. Kugeza ubu, mubushinwa hari inganda nyinshi zidasanzwe zogosha ifu yubutaka mubushinwa, hamwe nubuso bwa toni zirenga icumi. Baotou Tianjiao Qingmei Rare Earth Polishing Powder Co., Ltd, umushinga uhuriweho n’amahanga mu Bushinwa, kuri ubu ni rumwe mu nganda nini nini zidasanzwe zangiza amashanyarazi mu Bushinwa, zifite umusaruro wa buri mwaka toni 1200 n’ibicuruzwa bigurishwa mu gihugu ndetse no ku rwego mpuzamahanga.
Kurimbisha ibirahuri
Ikirahuri cyose kirimo okiside ya fer, ishobora kwinjizwa mubirahuri hifashishijwe ibikoresho bibisi, umucanga, hekeste, hamwe nikirahure kimenetse mubirahuri. Hariho uburyo bubiri bwo kubaho: bumwe ni icyuma gihwanye, gihindura ibara ryikirahure mubururu bwijimye, naho ubundi nicyuma cyoroshye, gihindura ibara ryikirahure umuhondo. Guhindura ibara ni okiside ya ion ihwanye nicyuma kigereranije, kuko ubukana bwamabara yicyuma ni kimwe cya cumi cyicyuma kimwe. Noneho ongeramo toner kugirango uhindure ibara ibara ryatsi ryoroshye.
Ibintu bidasanzwe byisi bikoreshwa muguhindura ibirahuri ahanini ni cerium oxyde na neodymium oxyde. Gusimbuza ibintu bisanzwe byera arsenic decolorizing agent hamwe nubutaka budasanzwe bwikirahure cyogukora ibirahure ntabwo byongera imikorere gusa, ahubwo birinda no kwanduza arsenic yera. Cerium oxyde ikoreshwa muguhindura ibirahuri ifite ibyiza nkibikorwa bihamye byubushyuhe bwo hejuru, igiciro gito, kandi nta kwinjiza urumuri rugaragara.
Ibara ry'ikirahure
Ntibisanzwe isi ion ifite amabara ahamye kandi meza mubushyuhe bwinshi, kandi ikoreshwa muguhuza ibikoresho kugirango ikore ibirahuri bitandukanye. Ni gake cyane oxyde yisi nka neodymium, praseodymium, erbium, na cerium ni amabara meza cyane. Iyo ikirahuri kibonerana gifite amabara adasanzwe yisi akurura urumuri rugaragara hamwe nuburebure bwumurambararo uri hagati ya 400 na 700 nanometero, byerekana amabara meza. Ibirahuri byamabara birashobora gukoreshwa mugukora amatara yerekana indege no kugendagenda, ibinyabiziga bitandukanye byo gutwara abantu, hamwe nudushusho twinshi two mu rwego rwo hejuru.
Iyo okiside ya neodymium yongewemo ikirahuri cya sodium calcium hamwe nikirahure cya Lead, ibara ryikirahure riterwa nubunini bwikirahure, ibirimo neodymium nuburemere bwisoko yumucyo. Ikirahure cyoroshye ni umutuku wijimye, naho ikirahure cyijimye ni ubururu. Iyi phenomenon yitwa neodymium dichroism; Okiside ya Praseodymium itanga ibara ryatsi risa na chromium; Okiside ya Erbium (III) ni umutuku iyo ikoreshejwe mu kirahure cya Photochromism hamwe nikirahure cya kirisiti; Gukomatanya cerium oxyde na titanium dioxyde itera ikirahuri umuhondo; Okiside ya Praseodymium na neodymium oxyde irashobora gukoreshwa mubirahuri byirabura bya praseodymium neodymium.
Ntibisanzwe isi isobanura
Gukoresha cerium oxyde aho gukoresha okiside ya arsenic gakondo nkikirahure cyerekana ibintu kugirango ukureho ibibyimba hamwe nibimenyetso byamabara bigira ingaruka zikomeye mugutegura amacupa yikirahure atagira ibara. Igicuruzwa cyarangiye gifite florescence yera, gukorera mu mucyo, no kunoza imbaraga zikirahure no kurwanya ubushyuhe. Muri icyo gihe, ikuraho kandi umwanda wa arsenic ku bidukikije no ku kirahure.
Byongeye kandi, kongera cerium oxyde mubirahuri bya buri munsi, nko kubaka nikirahure cyimodoka, ikirahure cya kirisiti, birashobora kugabanya itumanaho ryumucyo ultraviolet, kandi ikoreshwa ryatejwe imbere mubuyapani no muri Amerika. Hamwe n'izamuka ry'ubuzima mu Bushinwa, hazaba kandi isoko ryiza. Ongeramo neodymium oxyde mubirahuri by'ibirahure by'amashusho birashobora gukuraho ikwirakwizwa ry'urumuri rutukura kandi bikongera ubwumvikane. Ibirahuri bidasanzwe byongeweho isi bidasanzwe birimo ikirahuri cya lanthanum, gifite indangagaciro zikomeye kandi zidakwirakwizwa, kandi zikoreshwa cyane mugukora lens zitandukanye, kamera zateye imbere, hamwe na kamera, cyane cyane kubikoresho bifotora hejuru cyane; Ce ibirahuri byerekana imirasire, bikoreshwa mumodoka yikirahure na TV yikirahure; Ikirahuri cya Neodymium gikoreshwa nkibikoresho bya laser kandi nikintu cyiza cyane kuri lazeri nini, gikoreshwa cyane cyane mubikoresho bigenzurwa na nucleaire.
