Abstract:
A method of producing a ceramics film comprising the step of forming a ceramics film by crystallizing a ceramics source solution containing a first source solution and a second source solution. The first source solution is different in category from the second source solution, the former being used to produce ferroelectrics and the latter being used to produce oxides such as ABO system, a solvent contained in the former is different in polarity from that contained in the latter, and the first source solution and the second source solution are formed into films with phases separated to thereby form first crystals consisting of the first source solution intermittently in the plane direction of the ceramics film and form second crystals consisting of the second source solution so as to intervene between the first crystals.

Abstract:
A textured PMN-PZT ceramic is created using templated grain growth to align seed crystals in a ceramic matrix powder by tape-casting process. Heat treatment then results in the nucleation and growth of matrix crystals on aligned templates. The resulting textured PMN-PZT ceramic has high longitudinal piezoelectric coefficient and a high piezoelectric voltage coefficient. In another embodiment, a textured PMN-PT ceramic has a volume fraction of the templates no greater than 1%. The utility of this invention includes both its exceptional piezoelectric properties as well as the utilization of an economical manufacturing process that is widely used in the multi-layer ceramic capacitor industry.
