摘　　要：Green bodies of 25%CePO 4/ZrO 2 and ZrO 2 ceramics were joined at 1450℃ for 120 min without applied pressure by using mix ed powders slurries composed of CePO 4 and ZrO 2. The effects of CePO 4/(CePO 4+ZrO 2) ratio of the adhesive on the bond strength of the joints were invest igated. Maximum bond strength of 414MPa was obtained by joining an adhesive wit h the ratio of 0.5. Under the experimental conditions, the grain size of the par ticles grown in the joint was smaller than that in joined ceramics. The microstr ucture of the joint was more homogeneous than that of the matrix and without obv ious cracks, pores and other defects.Green bodies of 25%CePO 4/ZrO 2 and ZrO 2 ceramics were joined at 1450℃ for 120 min without applied pressure by using mix ed powders slurries composed of CePO 4 and ZrO 2.
