Synthesis of Ca(ZrxTi1-x )O3 perovskites for multilayer capacitors with non-noble metal frames
Abstract
Those works presents the synthesis of dielectrics ceramics belonging to the Ca(ZrxTi1-x)O3 system. In this domain of composition, the limits of the solid solution are controversial. At the end, the goal consist in the realization of multilayer capacitors of type I, and co-sinterable with copper inner electrodes. We will present the firsts results obtained for the values of x=1; 0,8; 0,7; 0,5; 0,3; 0,2; and 0.The synthesis by the classical solid-state route, in particular the blending-milling step of the raw powders CaCO3, TiO2 and ZrO2, was considerably investigate. The aim of this is to determine the better conditions of dispersion in an aqueous slurry. The mix of powders were calcined between 900°C and 1500°C. The densification of these different formulations was study by dilatometry. Sintering test were realize from 1200°C to 1500°C. After sintering, the samples were analyze by XRD, SEM and EDS. The dielectric properties at 1 kHz, between -20°C and 150°C and in high frequency will be measure too.The compositions (x=1; 0,8; 0,7; 0,2 and 0) seem to be single phased according to the XRD analysis. However, the compositions x=0,5 and 0,3 seem to contain a small amount of a parasite phase. For these compositions, some studies show a lot of secondary phases (Ref 1. 2.)The next steps of this work will consist of study the behavior of sintering in a reductive atmosphere and with an addition of sintering agent and doping elements.Ref (1) : Solubility limits and microwave dielectric properties of Ca(ZrxTi1-x)O3 solid solution, Parida et al.
