Yttria e tsitsitse zirconia, YSZ ke mofuta oa thepa ea ceramic. Ka ho eketsa Yttrium (III) oxide, mocheso oa phetoho ea mohato oa Zirconium dioxide o ka fetoloa ho hlahisa likristale tse tsitsitseng tsa cubic le likristale tsa tetragonal mocheso oa kamore.
Zirconia e hloekileng ke mohato oa monoclinic mocheso oa kamore. Ha mocheso o nyolohela ho 1173 ℃, o tla fetoha mohato oa tetragonal, 'me ha o nyolohela ho 2370 ℃, o tla fetoha mohato oa cubic. Ka 2690 ℃, e tla fetoha karolo ea mokelikeli.
Monoclinic phase (mohato phetoho mocheso: 1173 ° C) tetragonal phase (mohato phetoho mocheso: 2370 ° C) cubic phase (melting point/solidification point: 2690 ° C) mokelikeli.
Zirconia e hloekileng e pholile ho tloha mocheso o phahameng ho ea mocheso oa kamore, 'me ka mor'a hore e be mocheso oa phetoho ea mohato, kristale ea lisekoere e fetoloa kristale ea monoclinic. Ka lebaka la phetoho e matla ea molumo, sehlahisoa sa sintered se na le li-microcracks 'me hangata ha se sebelisoe. Zirconium dioxide ha e eo karolong ea li-cubic (sebopeho sa kristale ea fluorite) mocheso oa kamore, empa ka ho eketsa li-oxide tse ling, mocheso oa mocheso oa Zirconium dioxide o tsitsitseng karolong ea cubic o ka eketseha haholo. Zirconium dioxide e nang le phasestabilizer e bitsoa stabilized zirconias.
Lifaha tsa zirconia tse tsitsitseng tsa Yttrium li ka sebelisoa ho Electroceramics, lisebelisoa tsa makenete, zirconia, silicon oxide, Zirconium (IV) silicate, titanium dioxide, lijo tsa meriana, li-pigments, lidae, li-inks le liindasteri tse khethehileng tsa lik'hemik'hale. Lisebelisoa tsa refractory tsa Zirconia: li-crucibles tsa zirconia, likhoele tsa refractory tsa zirconia, lisebelisoa tsa sebōpi sa zirconia. Li-ceramics tsa meralo ea zirconia: li-bearings tsa zirconia tsa ceramic, li-valve tsa ceramic tsa zirconia, lisebelisoa tsa ho sila tsa zirconia. Li-ceramics tse sebetsang tsa zirconia: libolo tsa zirconia ceramic bakeng sa lipene tsa ballpoint, lisebelisoa tsa zirconia ceramic, zirconia tse futhumatsang mocheso o phahameng, zirconia bioceramics, lisebelisoa tsa ho roala zirconia, lisebelisoa tsa puisano tsa zirconia, lisebelisoa tsa oksijene tsa zirconia.
Re hlahisa phofo ea YSZ ka ho iketsetsa hydrolysis process.Ho latela litaba tse fapaneng tsa Y2O3, re ka hlahisa phofo e fapaneng ea YSZ. Lihlahisoa tse tloaelehileng ke 3Y-YSZ phofo e thehiloeng, e arotsoe ka phofo e kopantsoeng le phofo e sa tsitsang ho itšetlehile ka litlhoko tsa bareki. .Thepa ea 'mele e ne e ka kopana le litlhoko tse fapaneng tsa bareki bakeng sa khatiso e omileng, ho hatelloa ha isostatic, ente, ho lahlela, ho bopa ka ente, ho lahlela ka slip joalo-joalo.
