Ceramic Glaze Xim Cobalt Xiav

FULLN CHEMICAL ceramic glaze xim Cobalt Blue FU-5604 (Cobalt aluminium xiav) yog tsim los ntawm zinc oxide, cobalt oxide, alumina thiab lwm yam khoom siv raw los ntawm kev sib xyaw, calcination thiab micro hmoov ua. Nws yog ib hom inorganic ceramic pigment xiav. Nyob rau hauv cov txheej txheem ntawm kub calcination, zinc oxide, cobalt oxide, alumina tsim cov spinel siv lead ua qauv raws li sib txawv proportions. Nws muaj pes tsawg leeg yuav muaj ib los yog ob peb pawg ntawm boric acid, halide. FULLN CHEMICAL ceramic glaze xim Cobalt Blue yog tsim rau oxidizing cua firing thiab haum rau ntau yam ntawm glazes.

Nrog kev ua tiav cov txheej txheem tsim khoom thiab cov cuab yeej ntsuas qib siab, kev tswj hwm kev tswj hwm nruj thiab pab pawg muaj peev xwm muaj peev xwm ua kom ntseeg tau tias peb cov xim ceramic glaze muaj tag nrho cov xim thiab ruaj khov zoo. Cov series ntawm ceramic glaze xim Cobalt Blue cov ntaub ntawv yog nrog fineness tsawg dua 400 mesh, noo noo yog tsawg dua 0.5%. Nws tuaj yeem siv rau hauv thaj chaw ntawm cov nplais hauv pem teb, ceramic phab ntsa vuas, kos duab plooj (porcelains), cov khoom siv huv huv, thiab lwm yam.

Cobalt xiav xim yog lub npe nrov rau nws cov tawv nqaij, vivid xiav hue, tus cwj pwm los ntawm lub zog tinting siab thiab zoo heev xim purity. Nws yog dav nyiam nyob rau hauv kev lag luam rau nws lub peev xwm los tsim cov nplua nuj, opaque ntxoov xiav uas yog ntshaw nyob rau hauv ntau yam kev siv xws li xim, ceramics, plastics, thiab hais txog.

Dab tsi ua rau cov xim xiav?

Cobalt xiav yog ib txwm siv los ua thawj theem siv lead ua rau CoO Al2O3 spinel.Rau hom xim uas muaj Zn0 yog lub hiav txwv xiav.Co-A1-Si yog CoO·Al2O3 spinel tau los ntawm kev sib txuas cobalt oxide nrog kaolinite thiab paraffin.Co-Zn-Si xim yog tau los ntawm kev ntxiv ZnO thiab SiO2 rau cobalt oxide thiab ces hluav taws.

Hauv cov qauv silicon-zinc ore (Zn2SiO4), cov qauv hloov ntawm Co2+→Zn2+ ua rau Co2+ cov kua hauv Zn2SiO4.Cov qauv silica-zinc tau khaws cia (txog Ib nrab ntawm Zn2+ tau hloov los ntawm Co2+).Tom qab ntawd tsim cov xim liab thiab xiav xiav piv nrog CoO·Al2O3 spinel.

Cov xim Co-Si yog Co2SiO4 olivine tsim tom qab sintering los ntawm kev ntxiv SiO2 rau cobalt oxide.Cobalt tseem nyob rau hauv lub xeev Co2+ nyob rau hauv tag nrho cov saum toj no xim.Rau lub violet xiav, nws kuj muaj peev xwm ntxiv ib me me. Ntawm cobalt oxide rau glaze.Nyob rau hauv kev lag luam cobalt oxide, ib sab CoO, nws yog tov nrog Co3O4 [CoO·Co2O3]. Co3+ cuam tshuam rau cov xim xiav.Tom qab ntxiv 1% ~ 2% (feem pua ​​​​ntawm ntau) ntawm cobalt oxide rau glaze, nws yog tsis yooj yim sua kom disperse cobalt oxide tusyees nyob rau hauv lub glaze.Qhov no yog tib yam li ntxiv Cr2O3. Yog li ntawd, tsuas yog tom qab cobalt oxide yog diluted nyob rau hauv lub glaze nrog SiO2 thiab Al2O3 raws li lub ntsiab Cheebtsam, thiab ces ntxiv rau hauv lub glaze, tau Co2+ yuav sib npaug dispersed nyob rau hauv lub glaze nyob rau hauv ib tug bivalent xeev. hu ua cyanosis.

Cov muaj pes tsawg leeg ntawm Co-Si system xim yog Co2SiO4.Co2+ occupies tag nrho octahedral voidage, thiab nws coordination tooj yog 6, thiab nws cov xim yog purplish liab.Vim nws yog xiav xiav nyob rau hauv lub glaze, nws yog nyob rau hauv lub co-Si system xim. xiav xim.Zr-Si-V (zircon - zirconium xiav) yog lub ntsiab ntawm xiav. Nws yog greenish piv rau cobalt xiav.
