This study was about to make zirconia ceramics with yttria, using spraying precipitation method for the purpose of powder control. The powder properties and the characterization of sintered body, were studied. As the results, 1. The synthesized powder had homogeneity of spherical shape, and average particle size was 2-3 um. 2. Crystallization temperature increased with Y2O3 content. 3. Apparent density of sintered body (fired above 1500$^{circ}C$) was higher than 98% of theoretical value in 3 mol% Y2O3 content. 4. High KIC values(19kg/㎣/2) in 3 mol % Y2O3 content resulted from sintering density increasement.
