Notes:
(MgO)0.1-x(YO1.5)x(ZrO2)0.9 (MYZ) and (MgO)0.1-x(CaO)x(ZrO2)0.9 (MCZ) ceramics wereprepared and their phase composition, bulk density, flexural strength, and thermal shock resistance werecharacterized. There was an abrupt change of c/(c+m) from 29% to 75% as 0〈x〈0.01 for MYZ, and achange of c/(c+m) from 42% to 88% appeared as 0.02〈x〈0.03 for MCZ (the c and m representing thecontent of the cubic and the monoclinic phases respectively). When x=0.01~0.05, the resulting MYZspecimens had the resembling c/(c+m) at about 75%, and a thermal shock resistance of more than 5 times(1100oC⇔25oC) appeared for x=0.03~0.05 specimens. However for MCZ, only specimen of x=0.01with c/(c+m) of 33% had a thermal shock resistance more than 5 times
