PIEZOELECTRIC CERAMIC COMPOSITE

摘要

The present invention relates to a piezoelectric ceramic composite prepared by the following process, comprising the steps of: pulverize first powder selected from the group consisting of Fe2O3, Al2O3, Cr2O3 and Ga2O3; pulverize second powder selected from the group consisting of Ta2O5 and Nb2O5 and mixed with TiO2; mix first and second powders; pour mixed powders into a mold; press said mixed powders in said mold; and heat said pressed powders to plasticity under high pressure.
