Gutegura Ultrafine Ntibisanzwe ISI

GuteguraUltrafine idasanzwe Isi

Ultrafine Ntibisanzwe Ice Ibigize bifite uburyo bukoreshwa ugereranije nisi idasanzwe hamwe nibice rusange hamwe nubunini rusange, kandi ubu hari ubushakashatsi bwinshi kuri bo. Uburyo bwo gutegura bugabanijwemo uburyo buhamye bwicyiciro, uburyo bwa phase bwerekana, na gaze yicyiciro cya gaze ukurikije uko leta igeraho. Kugeza ubu, uburyo bwicyiciro cyamazi bukoreshwa cyane muri laboratoire ninganda kugirango bategure ifu ya ultrafine yisi idasanzwe. Ahanini ikubiyemo uburyo bwo kugwa, Mol Gel Moel, uburyo bwa hydrothermal, uburyo bwibimenyetso, uburyo bwa microemulsion hamwe nuburyo bwo kugwa bwa alkyd nuburyo bukwiye cyane kumusaruro winganda.

Uburyo bwonyine ni ukukongeraho Umunyu wumurongo wumunyu wicyuma, hanyuma akayunguruzo, gukaraba, byumye kandi ubushyuhe no gushyuha no gushyushya no kubora ifu. Harimo uburyo bwimvura, uburyo bwimvura nu mbaraga nuburyo bwo kwirinda. Muburyo busanzwe bwo kugwa, oxide idasanzwe nintama idasanzwe yisi irimo acide ihindagurika irashobora kuboneka mugutwikwa no gutwikwa, hamwe nubunini bwa 3-5 μ m. Ahantu runaka ahantu hatari munsi ya 10 ㎡ / g kandi ntabwo bifite imitungo idasanzwe yumubiri na shimi. Uburyo bwa AmoniUmium

Ubushakashatsi bwerekanye ko ibintu nyamukuru bireba ingano ya farrafer detrafine idasanzwe mu buryo bw'isi ya ailmoum mu gisubizo, ubushyuhe bw'imvura, n'ibindi. Kurugero, mubushakashatsi bwa Y3 + + kugirango bategure Y2O3, mugihe ifu idasanzwe yisi idasanzwe iva mumvura yo kumeneka yumiwe no gukama ni muto, imyenda ni meza.

Mubisubizo byimiti, ubushyuhe ni ikintu gikomeye. Mu bushakashatsi bwavuzwe haruguru, iyo ubushyuhe buri mu 60-70 ℃, imvura iratinda, kuzungura byihuta, ibice birarekurwa kandi bikabije, kandi birakabije; Iyo ubushyuhe bwimyitwarire buri munsi ya 50 ℃, ikumbi yihuta, ifite ibinyampeke nibindi binini bito. Mugihe c'igisubizo, umubare wa CO2 na NH3 urengerewe ni bike, kandi imvura iri muburyo bukomeye, budakwiriye gukandakara no gukaraba. Nyuma yo gutwikwa muri yttrium oxide, haracyariho ibintu bibujije bikabije bitera bikomeye kandi bifite ingano nini. Kwibanda kuri Ammonium Bicarbonate nabyo bigira ingaruka ku bunini bwa ytrike. Iyo kwibanda kuri Ammonium bicarbonate biri munsi ya 1Mol / l, ibyatsi bya Ytride oxide nini nicyamwe kandi kimwe; Iyo kwibanda kuri Ammonium bicarbonate birenze 1Mol / l, imvura yibanze izabaho, itera guhungira hamwe nibice binini. Muburyo bukwiye, ingano ya 0.01-0.5 irashobora kuboneka μ m ultrafine yttrium oxide ifu.

Muburyo bwimvura ya Oxalate, igisubizo cya Oxalic cyongeweho mugihe Ammonia yongeweho kugirango abone agaciro ka PH muburyo bwo kwifata, bikavamo ubunini bwa μ m ya yttrium oxide ifu. Ubwa mbere, metrike ya Ytriam Nittrate Amazi ya Amoni kugirango abone yttrixide ya yttriim Ongeraho Edta kuri Y3 + igisubizo cya Yttrium nittrate hamwe na 0.25-0.5Mol / l, min my Ifu ya yttrium hamwe nubunini bwa 40-100nm irashobora kuboneka.

Mugihe cyo kwiteguraUltrafine idasanzwe IsiUbworoherane, impamyabumenyi zitandukanye zo guterana zikunda kubaho. Kubwibyo, mugihe cyo kwitegura, ni ngombwa kugenzura byimazeyo synthesis, mugukoresha agaciro ka PH, ukoresheje ababanjirije, ukoresheje abatatanyaga, nubundi buryo kugirango ukwirakwize byimazeyo ibicuruzwa hagati. Noneho, uburyo bukwiye bwumisha bwatoranijwe, amaherezo, bwatatatatatatatatanda imbaraga zisi Ultrafine yisi yabonetse binyuze muburaro.
