ʻO Yttria stabilized zirconia, ʻo YSZ kahi ʻano mea seramika. Ma ka hoʻohui ʻana i ka Yttrium(III) oxide, hiki ke hoʻololi ʻia ka pae wela o ka hoʻololi ʻana o ka pae o Zirconium dioxide e hana i nā kristal cubic paʻa a me nā kristal tetragonal i ka wela lumi.
ʻO ka zirconia maʻemaʻe kahi manawa monoclinic i ka lumi wela. Ke piʻi ka mahana ma kahi o 1173 ℃, e hoʻololi ia i kahi pae tetragonal, a i ka piʻi ʻana i 2370 ℃, e hoʻololi ʻia ia i kahi pae cubic. Ma 2690 ℃, e lilo ia i mea wai.
Māhele Monoclinic (pae wela hoʻololi: 1173 ° C) pae tetragonal (mahana hoʻololi manawa: 2370 ° C) ʻāpana cubic (helu heheʻe / solidification point: 2690 ° C) wai.
Hoʻomaʻalili ʻia ka zirconia maʻemaʻe mai ka wela kiʻekiʻe a hiki i ka lumi wela, a ma hope o ka hoʻololi ʻana i ka mahana, ua hoʻololi ʻia ke aniani square i ke aniani monoclinic. Ma muli o kona loli nui ʻana, loaʻa nā microcracks i ka huahana sintered a ʻaʻole hiki ke hoʻohana pinepine ʻia. ʻAʻole noho ʻo Zirconium dioxide i loko o ka pae cubic (fluorite crystal structure) i ka lumi wela, akā ma ka hoʻohui ʻana i nā oxides ʻē aʻe, hiki ke hoʻonui nui ʻia ka pae wela o ka Zirconium dioxide i hoʻopaʻa ʻia i ka pae cubic. ʻO ka Zirconium dioxide doped me ka phase stabilizer i kapa ʻia ʻo stabilized zirconias.
Hiki ke hoʻohana ʻia nā pahu zirconia i hoʻopaʻa ʻia i ka Electroceramics, nā mea magnetic, zirconia, silicon oxide, Zirconium(IV) silicate, titanium dioxide, meaʻai lāʻau lapaʻau, pigments, dyes, inks, a me nā ʻoihana kemika kūikawā. ʻO nā mea hoʻoheheʻe Zirconia: zirconia crucibles, zirconia refractory fibers, zirconia kiln mea. Zirconia structural ceramics: zirconia ceramic bearings, zirconia ceramic valves, zirconia grinding materials. Zirconia mea hana hana: zirconia ceramic poepoe no ka ballpoint peni, zirconia ceramic mea paahana, zirconia kiʻekiʻe-mehana meahana, zirconia bioceramics, zirconia uhi mea, zirconia mea kamaʻilio, zirconia oxygen sensors.
Hoʻopuka mākou i ka pauka YSZ ma o ka hoʻolahaʻana i ka hydrolysis process.Ma muli o nā mea likeʻole o Y2O3, hiki iā mākou ke hana i nā mea likeʻole YSZ pauka. ʻO nā huahana maʻamau he 3Y-YSZ ka pauka, hoʻokaʻawaleʻia i ka pauka paʻa a me ka paukaʻole e like me nā koi o nā mea kūʻai. . Hiki i nā waiwai kino ke hoʻokō i nā koi o nā mea kūʻai aku no ke kaomi maloʻo, kaomi isostatic, injection, hoʻolei, hoʻoheheʻe ʻia, hoʻoheheʻe ʻia a pēlā aku.
