ZIRCONIA CERAMIC, METHOD FOR PREPARING ZIRCONIA CERAMIC, USE THEREOF, AND COMPOSITION INCLUDING THE SAME

CHEN GE / LIN XINPING / TANG WEI

A zirconia ceramic includes the following elements: 60.5-70.5 wt % of Zr, 2.5-5.45 wt % of Y, 0.05-2.65 wt % of Al, 0.015-1.07 wt % of Si, and 0.34-2.8 wt % of M. M includes at least one of Nb or Ta. The zirconia ceramic has a phase composition which includes tetragonal zirconia, alumina and zirconium silicate. The total content of alumina and zirconium silicate is 0.2-12 wt %, and the content of the tetragonal zirconia is 84-99.3 wt %. The tetragonal zirconia includes a solid solution of zirconia formed with yttrium oxide and MxOy, x satisfies 1≤x≤3, and y satisfies 3≤y≤6.
