Abstract: Effects of interlayer composition on bonding strength and interfacial microstruc ture of green joined CePO4-ZrO2 ceramics were studied. Green bodies of 25%C ePO4/ZrO2 and ZrO2 ceramics were joined by using interlayer composed of Ce PO4 and ZrO2 at 1450 ℃ for 120 min without applied pressure.The effects of CePO4/(CePO4+ZrO2) ratio on the bond strength of the joints were investiga ted. Under the experimental conditions, the grain size of the particles grown in the joint is smaller than those in joined ceramics. The microstructure of the joint is more homogeneous than that of the matrix and without obvious cracks, pores and other defects.
