Imiterere ya Crystal ya yttrium oxyde
Yttrium oxyde (Y.2O3) ni isi yera yera idasanzwe idashonga mumazi na alkali kandi igashonga muri aside.Nubwoko busanzwe bwa C bwisi budasanzwe sesquioxide hamwe nububiko bushingiye kumubiri.
Imbonerahamwe ya Crystal Imbonerahamwe ya Y.2O3
Imiterere ya Crystal Igishushanyo cya Y.2O3
Imiterere yumubiri na chimique ya yttrium oxyde
(1) ubwinshi bwimyanda ni 225.82g / mol naho ubucucike ni 5.01g / cm3;
(2) Ingingo yo gushonga 2410℃, ingingo ibira 4300℃, ubushyuhe bwiza bwumuriro;
(3) Imyitwarire myiza yumubiri nubumashini hamwe no kurwanya ruswa;
.3Al5O12), bifite akamaro kanini mugukoresha nka laser ikora;
.
(6) Ingufu za fonon ziri hasi, kandi impinga ikomeye ya Raman igaragara kuri 377cm-1, bifite akamaro kugabanya amahirwe yinzibacyuho idafite imirasire no kunoza imikorere-ihindagurika;
(7) Munsi ya 2200℃, Y.2O3ni icyiciro cya cubic nta birefringence.Igipimo cyo kuvunika ni 1.89 ku burebure bwa 1050nm.Guhindura mubice bitandatu hejuru ya 2200℃;
(8) Ikinyuranyo cyingufu za Y.2O3ni mugari cyane, kugeza kuri 5.5eV, kandi urwego rwingufu za doped trivalent zidasanzwe isi luminescent ion iri hagati ya valence band na bande ya Y2O3no hejuru yingufu za Fermi, bityo bigakora centre ya luminescent.
(9) Y.2O3, nkibikoresho bya matrix, irashobora kwakira cyane ubutumburuke bwisi budasanzwe ion kandi igasimbuza Y.3+ion udateye impinduka zubaka.
Imikoreshereze nyamukuru ya okiside ya yttrium
Okiside ya Yttrium, nkibikoresho byongera imbaraga, ikoreshwa cyane mubice byingufu za atome, ikirere, fluorescence, electronics, ceramics yubuhanga buhanitse nibindi kubera imiterere yumubiri myiza nka dielectric ihoraho, irwanya ubushyuhe bwiza hamwe na ruswa ikomeye kurwanywa.
Inkomoko yishusho: Umuyoboro
1, Nka materix ya fosifori, ikoreshwa mubice byo kwerekana, kumurika no gushiraho ikimenyetso;
2, Nka laser igikoresho giciriritse, ceramics ibonerana ifite imikorere ihanitse ya optique irashobora gutegurwa, ishobora gukoreshwa nkigikoresho cya laser kugirango hamenyekane ubushyuhe bwicyumba cya laser;
3, Nkibikoresho byo hejuru bya matrike ya luminescent, ikoreshwa mugutahura infragre, ibimenyetso bya fluorescence nibindi bice;
4.
5, Irashobora gukoreshwa nkibikoresho byerekana, ibikoresho birwanya ubushyuhe bwinshi, ibikoresho bivunika, nibindi.
6, Nkibikoresho fatizo cyangwa inyongeramusaruro, bikoreshwa cyane mubikoresho byo hejuru yubushyuhe bwo hejuru, ibikoresho bya kirisiti ya laser, ibikoresho byububiko bwububiko, ibikoresho bya catalitiki, ceramique dielectric, amavuta meza cyane hamwe nizindi nzego.
Uburyo bwo gutegura ifu ya yttrium
Uburyo bwimvura yimvura ikoreshwa muburyo bwo gutegura okiside yisi idasanzwe, ikubiyemo cyane cyane uburyo bwo kugusha imvura ya oxyde, uburyo bwo kugwa kwa amonium bicarbonate, uburyo bwa urea hydrolysis nuburyo bwo kugwa kwa amoniya.Mubyongeyeho, spray granulation nuburyo bwo gutegura bwagiye buhangayikishwa cyane nubu.Uburyo bwo kugwa umunyu
1. uburyo bwo kugwa kwa oxalate
Ubutaka budasanzwe bwisi bwateguwe nuburyo bwimvura ya oxalate bufite ibyiza byo kurwego rwo hejuru rwa kristalisiti, uburyo bwiza bwa kirisiti, umuvuduko wo kuyungurura byihuse, ibintu bitanduye kandi bikora byoroshye, ubwo ni uburyo busanzwe bwo gutegura isuku ryinshi rya oxyde yisi idasanzwe mubikorwa byinganda.
Uburyo bwo kugwa kwa Ammonium bicarbonate
2. Uburyo bwimvura ya Amonium bicarbonate
Ammonium bicarbonate ni imvura ihendutse.Mu bihe byashize, abantu bakunze gukoresha uburyo bwo kugwa kwa ammonium bicarbonate kugirango bategure karubone ivanze idasanzwe ivuye mumuti wubutaka budasanzwe.Kugeza ubu, isi idasanzwe ya okiside itegurwa nuburyo bwimvura ya ammonium bicarbonate mu nganda.Mubisanzwe, uburyo bwo kugwa kwa ammonium bicarbonate ni ukongeramo ammonium bicarbonate ikomeye cyangwa igisubizo mumuti wa chloride idasanzwe ku bushyuhe runaka, Nyuma yo gusaza, gukaraba, gukama no gutwika, haboneka oxyde.Nyamara, bitewe numubare munini wibibyimba byakozwe mugihe cyimvura ya ammonium bicarbonate hamwe nagaciro ka pH idahindagurika mugihe cyimvura yaguye, igipimo cya nucleation kirihuta cyangwa kigenda gahoro, kikaba kidafasha gukura kwa kristu.Kugirango ubone oxyde ifite ingano nini nini na morphologie, imiterere yimyitwarire igomba kugenzurwa cyane.
3. Imvura ya Urea
Uburyo bw'imvura ya Urea bukoreshwa cyane mugutegura isi ya okiside idasanzwe, ntabwo ihendutse kandi yoroshye gukora, ariko kandi ifite ubushobozi bwo kugera kugenzura neza nucleation ya precursor no gukura kw'ibice, kuburyo rero imvura igwa muri urea yakwegereye abantu benshi kandi benshi gutonesha no gukurura ibitekerezo nubushakashatsi bwakozwe nintiti nyinshi kurubu.
4. Shira granulation
Ikoreshwa rya tekinoroji ya granulation ifite ibyiza byo kwikora cyane, umusaruro mwinshi hamwe nubwiza buhanitse bwifu yicyatsi, bityo spray granulation yabaye uburyo bukoreshwa muburyo bwo guhunika ifu.
Mu myaka yashize, ikoreshwa ryisi idasanzwe mumirima gakondo ntabwo ryahindutse cyane, ariko ikoreshwa mubikoresho bishya ryiyongereye kuburyo bugaragara.Nkibikoresho bishya, nano Y.2O3ifite umurongo mugari wo gusaba.Muri iki gihe, hari uburyo bwinshi bwo gutegura nano Y.2O3ibikoresho, bishobora kugabanywamo ibyiciro bitatu: uburyo bwicyiciro cyamazi, uburyo bwa gaz gaz nuburyo bukomeye bwicyiciro, muribwo buryo bwicyiciro cyamazi aribwo bukoreshwa cyane.Bigabanyijemo spray pyrolysis, hydrothermal synthesis, microemulsion, sol-gel, gutwika synthesis hamwe nimvura.Nyamara, spheroidized yttrium oxyde nanoparticles izaba ifite ubuso bwihariye bwihariye, ingufu zubutaka, amazi meza no gutatanya, bikwiye kwibandaho.
