Rigid inclusions retard the densification of matrices. This study deals with the effects of inclusion/matrix particle size ratio and surface modification of inclusions on the densification of Ag matrix. The surface of YSZ inclusions was modified by chemical roughening and/or electroless Ag-plating. The sintering behavior and microstructure development of Ag-matrix composites containing surface-modified YSZ with different inclusion/matrix particle size ratio were investigated. The densification of the matrix with higher inclusion content and/or smaller inclusion/matrix particle size ratio was suppressed more significantly, irrespective of the sinterability of matrix. The chemical surface roughening of inclusions resulted in an increase in the hindrance of densification of matrix. On the other hand, the electroless Ag-plating of inclusions relaxed the hindrance of the densification. The densification of matrix with high inclusion/matrix particle size ratio led to the formation of density variation in the matrix. Pores located around inclusion particles remained in the matrix with low inclusion/matrix particle size ratio. Channel structure of pores formed in the matrix, particularly when the particle sizes of matrix powder and inclusion powder were almost the same.
