LEAD-FREE PIEZO-ELECTRIC PORCELAIN COMPOSITION, PIEZO-ELECTRIC ELEMENT USING THE SAME, AND METHOD FOR PRODUCING LEAD-FREE PIEZO-ELECTRIC PORCELAIN COMPOSITION
A lead-free piezo-electric porcelain composition which contains a main phase having voids and which is formed of a first crystal phase composed of an alkali niobate/tantalate-based perovskite oxide having piezo-electric characteristics; and a sub-phase containing a second crystal phase composed of an A 2 B 6 O 13 -based compound (where the element A is a monovalent element and the element B is one or more divalent to hexavalent elements). The sub-phase fills voids present in the main phase.
