ʻO Zirconia kahi mea me ka ikaika mechanical kiʻekiʻe a me ka paʻakikī haʻihaʻi ma ka lumi wela.Hoʻohui ʻia kā mākou zirconia (ZrO2) me 3mol%Y2O3 ʻāpana zirconia paʻa (PSZ).Ma muli o ka liʻiliʻi o ke anawaena o nā mea PSZ, hiki ke hana ʻia me ka pololei kiʻekiʻe, a ke hoʻonui nei kāna noi ʻana i nā ʻāpana mīkini kikoʻī e like me nā mold.Eia kekahi, hiki ke hoʻohana ʻia no nā mea hana ʻenehana, nā ʻāpana hoʻohui optical a me nā mea hana ʻōpala.Hiki ke hoʻohana ʻia ka paʻakikī haʻihaʻi kiʻekiʻe o PSZ e hana i nā pūnāwai kūikawā, a hoʻohana nui ʻia i nā pahi seramika home, slicer a me nā ʻāpana ʻē aʻe.
ʻO nā hiʻohiʻona nui o nā ʻāpana ceramic zirconia:
1. ʻOi aku ka maikaʻi o ka pale ʻana, ʻoi aku ka kiʻekiʻe o 276 mau manawa ma mua o ke kila kila
2. ʻOi aku ka nui ma mua o ka nui o nā seramika loea, ʻoi aku ma mua o 6 g/cm3
3. ʻO ka paʻakikī kiʻekiʻe, ma luna o 1300 MPa no Vicker
4. Hiki ke pale i nā mahana kiʻekiʻe a hiki i 2400 °
5. Haʻahaʻa thermal conductivity, emi ma lalo o 3 W/mk ma lumi wela
6. Ka helu like o ka hoʻonui wela e like me ke kila kila
7. Hiki i ka 8 Mpa m1/2 ka paakiki o ka ha'i
8. Kemika inertness, elemakule kū'ē, a me ka rust mau loa
9. Ke kū'ē i nā metala i hoʻoheheʻeʻia ma muli o kahi helu hoʻoheheʻe kupaianaha.
