Raw cov ntaub ntawv rau hlau zirconium thiab nws cov tebchaw
Siv rau kev ua hlau zirconium thiab zirconium tebchaw, ua refractory cib thiab crucibles, high-frequency ceramics, abrasive cov ntaub ntawv, ceramic pigments thiab zirconates, thiab lwm yam. Feem ntau yog siv rau piezoelectric ceramic khoom, niaj hnub ceramics, refractory cov ntaub ntawv thiab precious hlau smelting. Zirconium bricks, zirconium tubes, crucibles, thiab lwm yam kuj siv nyob rau hauv zus tau tej cov hlau thiab non-ferrous hlau, optical iav thiab zirconium dioxide fibers. Kuj tseem siv rau hauv cov xim ceramic, electrostatic coatings thiab ci varnishes. Siv nyob rau hauv epoxy resins kom tiv thaiv corrosion los ntawm dej ntsev kub.
Cov khoom siv refractory
Zirconia fiber yog polycrystalline refractory fiber ntau. Vim lub siab melting point, tsis-oxidation thiab lwm yam high-temperature zog ntawm ZrO2 cov khoom nws tus kheej, ZrO2 fiber muaj ib tug siab kev pab cuam kub tshaj li lwm yam refractory fiber ntau yam xws li alumina fiber, mullite fiber, aluminium silicate fiber thiab thiaj li nyob. Zirconia fiber ntau tau siv rau lub sijhawm ntev hauv qhov kub thiab txias oxidizing cua tshaj 1500 ℃. Qhov siab tshaj plaws ua haujlwm kub yog siab li 2200 ℃. Nws tseem tuaj yeem tswj tau qhov ua tiav fiber ntau txawm tias nyob ntawm 2500 ℃. Nws muaj cov khoom siv hluav taws xob kub ruaj khov, tiv thaiv corrosion, oxidation tsis kam, thermal shock resistance, Non-volatile thiab tsis muaj kuab paug, tam sim no yog cov khoom siv fiber ntau tshaj plaws hauv ntiaj teb. Cov kua qaub thiab alkali corrosion kuj ntawm ZrO2 muaj zog ntau dua li ntawm SiO2 thiab Al2O3. Insoluble hauv dej, soluble hauv sulfuric acid thiab hydrofluoric acid; me ntsis soluble nyob rau hauv hydrochloric acid thiab nitric acid. Nws tuaj yeem fuse nrog alkali los tsim zirconate.
gas turbine
Daim ntawv thov ntawm cov plasma sprayed zirconium dioxide thermal barrier coatings ntawm aviation thiab industrial gas turbines tau ua tau zoo, thiab tau siv nyob rau hauv lub turbine ib feem ntawm cov roj turbines rau ib yam dab tsi. Txij li cov txheej no tuaj yeem txo qhov kub ntawm cov cua txias ntawm cov cua txias los ntawm 50 ~ 200 ° C, nws tuaj yeem txhim kho qhov ua haujlwm ntawm cov khoom kub kub, lossis tso cai rau cov roj kub kom nce lossis cov roj cua txias yuav tsum tau ua. txo qis thaum tswj qhov kub thiab txias ntawm cov khoom siv high-temperature. kev hloov pauv, yog li txhim kho kev ua haujlwm ntawm lub cav.
Cov khoom siv ceramic
Vim nws qhov loj refractive index, siab melting point thiab muaj zog corrosion kuj, zirconia yog siv los ua raw khoom nyob rau hauv lub kiln kev lag luam. Piezoelectric ceramic khoom muaj xws li lim, hais lus, ultrasonic underwater suab ntes, thiab lwm yam. Muaj kuj muaj niaj hnub ceramics (industrial ceramic glazes), zirconium bricks thiab zirconium hlab rau precious hlau smelting, thiab lwm yam Nanoscale zirconia kuj siv tau raws li ib tug matrix khoom rau polishing. Cov neeg sawv cev, cov nplej abrasive, piezoelectric ceramics, precision ceramics, ceramic glazes thiab high-temperature pigments.
lwm yam
Tsis tas li ntawd, zirconia tuaj yeem siv rau hauv kev tsim cov roj teeb roj teeb, enamel, iav dawb, refractory crucibles, thiab lwm yam X-ray yees duab. Abrasive cov ntaub ntawv. Ua ke nrog yttrium, nws yog siv los tsim cov teeb pom kev zoo hauv infrared spectrometers, tuab zaj duab xis Circuit Court capacitor cov ntaub ntawv, thiab cov qauv piezoelectric siv lead ua transducer.
Solid Oxide Fuel Cell (SOFC) yog cov roj cell thib peb. Nws yog ib qho khoom siv tag nrho-lub xeev uas ncaj qha hloov cov tshuaj siv hluav taws xob khaws cia hauv cov roj thiab oxidant rau hauv hluav taws xob hluav taws xob zoo thiab tus phooj ywg ib puag ncig ntawm qhov nruab nrab thiab siab kub. Cov khoom siv hluav taws xob tsim hluav taws xob. Nws feem ntau suav hais tias yog cov roj hluav taws xob uas yuav siv dav raws li cov khoom siv hluav taws xob hloov pauv hluav taws xob (PEMFC) yav tom ntej.
Muaj ob yam khoom hauv SOFC, uas yog lub anode thiab electrolyte, ob qho tib si yog Yttria Stabilized Zirconia (YSZ).
1. Yttrium-stabilized nano-zirconia siv los ua anode hauv SOFC system
Cov tshuaj tiv thaiv SOFC suav nrog kev sib cuag ntawm peb yam khoom: roj lossis oxygen (feem ntau yog cua), electrolyte (khoom los yog kua) thiab electrode. Peb-theem kev sib cuag yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv kev tsim roj cell. Cov thev naus laus zis tseem ceeb ntawm SOFC tau cuam tshuam rau hauv cov ntaub ntawv ntawm cov khoom siv roj teeb Hauv cov ntsiab lus ntawm kev xaiv, kev txhawb nqa anode hauv SOFC system siv Y2O3 nrog cov molar feem ntawm 8% doped hauv zirconia ceramics (thickness 1mm), thiab cov txheej txheem anode ua haujlwm yog NiO + YSZ zaj duab xis nrog lub thickness ntawm 10 mus rau 20μm. Tshwj xeeb yttrium-stabilized nano-zirconia rau roj teeb yog daim ntawv thov Cov khoom siv zoo tshaj plaws rau cov khoom siv roj oxide.
2. Yttrium-stabilized nano-zirconia siv los ua electrolyte hauv SOFC system
Cov khoom siv feem ntau siv rau SOFC electrolyte yog zirconia, tab sis cov conductivity ntawm zirconia ntshiab yog tsawg heev ntawm 1000 ° C, 10-7S·cm-1, uas yog ze rau cov khoom siv insulating. Cov conductivity ntawm oxygen ions tsis zoo, thiab doping feem ntau yog siv. Txhim kho nws cov conductivity, yog li yttria-doped zirconia yog siv los txhim kho nws cov conductivity. Yttrium-stabilized nano-zirconia muaj kev ua haujlwm zoo rau oxidation thiab txo qis, pheej yig thiab yooj yim kom tau, thiab muaj cov pa oxygen ion txaus txaus ntawm qhov kub thiab txias, zoo tshuaj stability thiab txhua yam khoom, yog li nws yog siv los npaj electrolyte films rau SOFCs.
Muaj ob yam uas cuam tshuam rau kev ua haujlwm ntawm yttrium-stabilized zirconia (YSZ) nyob rau hauv high-temperature fuel cell systems: impurity content and particle size. Vim hais tias ultra-nplua hmoov muaj thaj tsam loj heev, sintering tsav quab yuam ntawm cov khoom nce sharply, tus nqi diffusion kuj nce, thiab txoj kev diffusion shortening, yog li ua kom ceev cov txheej txheem sintering thiab txo qhov kub ntawm sintering, uas muaj txiaj ntsig zoo. kev npaj ntawm cov khoom tom qab. Thiab vim hais tias cov electrolyte plays lub luag hauj lwm ntawm lub cev cais tawm txheej nyob rau hauv lub roj cell, nws yuav tsum tau tsim ib tug ntom qauv, uas kuj yuav tsum tau cov hmoov yuav tsum me me nyob rau hauv loj thiab uniform nyob rau hauv particle loj. Yttrium-stabilized nano-zirconia particle loj yog 50-80nm, nrog zoo nanoparticle loj, uniform particle loj tis, tsis muaj zog agglomeration thiab zoo sphericity. Cov khoom siv hluav taws xob ntawm cov khoom sib txawv doped yog dav siv hauv kev tsim cov khoom siv roj oxide.
