Raw zvinhu zvesimbi zirconium nemakomponi ayo
Inoshandiswa kugadzira metallic zirconium uye zirconium compounds, kugadzira zvidhinha zvinoramba uye crucibles, high-frequency ceramics, abrasive materials, ceramic pigments uye zirconates, etc. Inonyanya kushandiswa piezoelectric ceramic products, daily ceramics, refractory materials uye simbi inokosha yakanyungudutswa. Zirconium zvidhinha, zirconium tubes, crucibles, etc. Inoshandiswawo mukugadzirwa kwesimbi uye isina-ferrous simbi, optical glass uye zirconium dioxide fibers. Inoshandiswawo muceramic pigments, electrostatic coatings uye baking varnishes. Inoshandiswa mu epoxy resins kuti iwedzere kuramba kune ngura nemvura inopisa yemunyu.
Refractory zvinhu
Zirconia fiber ndeye polycrystalline refractory fiber zvinhu. Nekuda kweiyo yakanyanya kunyungudika, isiri-oxidation uye zvimwe zvakanyanya-tembiricha zvimiro zveZrO2 zvinhu pachayo, ZrO2 fiber ine yakakwirira sevhisi tembiricha kupfuura mamwe refractory fiber mhando senge alumina fiber, mullite fiber, aluminium silicate fiber zvichingodaro. Zirconia fiber yave ichishandiswa kwenguva yakareba mune yekupedzisira-yepamusoro tembiricha oxidizing mamiriro ari pamusoro pe1500 ℃. Iyo yakanyanya tembiricha yekushanda inosvika 2200 ℃. Iyo inogona kuramba ichichengetedza iyo yakazara fiber chimiro kunyangwe pa2500 ℃. Iyo ine yakagadzikana yakakwirira-yekushisa yemakemikari zvivakwa, corrosion resistance, oxidation resistance, thermal shock resistance, Isiri-inovhuvhuta uye isina kusvibiswa-isina, parizvino ndiyo yakanyanya kusimukira fiber zvinhu munyika. Iyo asidhi uye alkali corrosion resistance yeZrO2 yakasimba kudarika iyo yeSiO2 neAl2O3. Insoluble mumvura, soluble mu sulfuric acid uye hydrofluoric acid; inonyungudika zvishoma muhydrochloric acid uye nitric acid. Inogona kusanganisa nealkali kuita zirconate.
turbine gasi
Kushandiswa kweplasma yakapfapfaidzwa zirconium dioxide thermal barrier coatings pamusoro pendege uye maindasitiri gasi turbines kwaita kufambira mberi kukuru, uye kwakashandiswa muchikamu cheturbine chegasi turbines kusvika pamwero wakati. Sezvo kupfeka uku kuchigona kuderedza kupisa kwemhepo-yakatonhodzwa kwepamusoro-tembiricha yezvikamu ne50 ~ 200 ° C, inogona kuvandudza zvakanyanya kusimba kwezvikamu zvepamusoro-tembiricha, kana kubvumira tembiricha yegesi kuti iwedzere kana huwandu hwegasi rekutonhora rinodiwa kuderedzwa paunenge uchichengetedza kutonhora kwezvikamu zvepamusoro-tembiricha. kuchinja, nokudaro kuvandudza kushanda kweinjini.
Ceramic zvinhu
Nekuda kweiyo hombe refractive index, yakakwira kunyungudika uye yakasimba corrosion kuramba, zirconia inoshandiswa seyakabikwa muindasitiri yevira. Piezoelectric ceramic products zvinosanganisira mafirita, maspeaker, ultrasonic underwater sound detectors, etc. Kunewo mazuva ese ceramics (industrial ceramic glazes), zirconium zvidhinha uye zirconium tubes ekunyungudutswa kwesimbi inokosha, etc. Nanoscale zirconia inogonawo kushandiswa sematrix zvinhu zvekupukuta. maajenti, zviyo zvinoputika, piezoelectric ceramics, precision ceramics, ceramic glazes uye high-temperature pigments.
zvimwe
Mukuwedzera, zirconia inogona kushandiswa mukugadzira incandescent gasi lampshades, enamel, girazi jena, refractory crucibles, etc. X-ray photography. Abrasive zvinhu. Pamwe chete neyttrium, inoshandiswa kugadzira mwenje sosi mwenje mune infrared spectrometers, gobvu firimu redunhu capacitor zvinhu, uye piezoelectric crystal transducer mafomula.
Solid Oxide Fuel Cell (SOFC) ndeyechitatu-chizvarwa chemafuta sero. Icho chinhu chakasimba-chakasimba-chinzvimbo chinoshandura zvakananga kemikari simba rakachengetwa muhuturu uye oxidant kuita simba remagetsi zvinogoneka uye rinoenderana nemamiriro ekunze pane tembiricha yepakati nepamusoro. Kemikari simba rekugadzira mudziyo. Inowanzo onekwa sehuturu sero ichashandiswa zvakanyanya seproton exchange membrane fuel cell (PEMFC) mune ramangwana.
Pane zvikamu zviviri muSOFC system, zvinoti anode ne electrolyte, zvese zviri Yttria Stabilized Zirconia (YSZ).
1. Yttrium-yakagadzikana nano-zirconia inoshandiswa seanode muSOFC system
Kuita kweSOFC kunosanganisira kubata kwezvinhu zvitatu: mafuta kana okisijeni (kazhinji mweya), electrolyte (yakasimba kana mvura) uye electrode. Matatu-chikamu kuonana ndeimwe yeakakosha matekinoroji mumafuta emafuta dhizaini. Iyo yakakosha tekinoroji yeSOFC inoratidzwa mumidziyo yemidziyo yebhatiri Panyaya yekusarudza, anode rutsigiro muSOFC system inoshandisa Y2O3 ine molar chikamu che8% doped mu zirconia ceramics (ukobvu 1mm), uye anode inoshanda layer ndeye NiO+YSZ firimu rine ukobvu hwegumi kusvika 20μm. Yakakosha yttrium-yakagadzika nano-zirconia yemabhatiri ndiyo yekushandisa Ideal zvinhu kune yakasimba oxide mafuta maseru.
2. Yttrium-yakagadzikana nano-zirconia inoshandiswa se electrolyte muSOFC system
Iyo inowanzoshandiswa zvinhu zveSOFC electrolyte i zirconia, asi conductivity ye zirconia yakachena yakaderera zvikuru pa 1000 ° C, 10-7S · cm-1, iri pedyo ne insulating material. Iko conductivity yeokisijeni ion yakashata, uye doping inowanzoshandiswa. Kuvandudza maitiro ayo, saka yttria-doped zirconia inoshandiswa kuvandudza maitiro ayo. Yttrium-yakadzikama nano-zirconia ine kumira kwakanaka kune oxidation uye kuderedza, yakachipa uye iri nyore kuwana, uye ine yakakwana yakakwira okisijeni ion conductivity pakupisa kwakanyanya, kugadzikana kwakanaka kwemakemikari uye ma mechanical properties, saka inoshandiswa kugadzira electrolyte mafirimu eSOFCs.
Pane zvinhu zviviri zvinokanganisa kushanda kweyttrium-stabilized zirconia (YSZ) mune yakakwirira-kupisa kwemafuta emagetsi emagetsi: kusvibiswa kwemukati uye chidimbu chekukura. Nekuti iyo yekupedzisira-yakatsetseka poda ine nzvimbo hombe yepamusoro, iyo sintering yekutyaira yechinhu inowedzera zvakanyanya, chiyero chekupararira chinowedzerawo, uye nzira yekuparadzira ipfupi, nekudaro ichimhanyisa zvakanyanya nzira yekupisa uye kudzikisa tembiricha yekupisa, iyo inobatsira kugadzirira kwezvikamu zvinotevera. Uye nekuti iyo electrolyte inobata chinzvimbo chekuzviparadzanisa chemuviri musero remafuta, inoda kuumba dense chimiro, icho chinodawo kuti hupfu huve hudiki muhukuru uye yunifomu muhukuru hukuru. Yttrium-yakagadzikana nano-zirconia particle size ndeye 50-80nm, ine yakanaka nanoparticle size, yunifomu particle size distribution, hapana yakaoma agglomeration uye yakanaka sphericity. Iyo conductive zvivakwa zve doped zvakasiyana zvinhu zvinoshandiswa zvakanyanya mukugadzira yakasimba oxide mafuta masero.
