In this paper

the green body of ZrO2 ceramic were successfully prepared by gel-casting

of which solid contents are 36%

38%

40%

42% and 44%

respectively

then no pressure sintered at 1600℃

the property and microstructure of ZrO2 ceramic were investigated by Electronic Universal Testing Machine and SEM.The results show that

when solid content is 38%

they are the greatest value that the relative density

bending strength and fracture toughness of ZrO2 ceramic

which are 98.36%

921.34MPa and 11.49MPa·m1/2
