Measurements of the practical adhesion of screen-printed Ag films on BaTiO(3) substrates have been completed, showing that the interfacial crack propagation energy decreases rapidly with increasing silver volume porosity. A geometrical model is proposed to estimate the interface porosity, which is relevant for adhesion concerns, in function of the volume porosity of the sintered silver layer. Experimental results present more consistent tendencies after this transcripti
