<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a piezoelectric ceramic material, which makes it possible to control a piezoelectric property with higher reliability than that achieved conventionally and to take the full advantage of the property.SOLUTION: A method for manufacturing a piezoelectric ceramic material expressed by the following compositional formula (1), MMO(where Mand Mrepresent a metal atom respectively, and O represents an oxygen atom) and having a perovskite structure comprises: a solvothermal step for growing crystal of the piezoelectric ceramic material by performing a solvothermal treatment on a mixture. The mixture includes at least a crystal nucleus raw material which makes a nucleus in crystal growth of the piezoelectric ceramic material owing to the thermal treatment, a first metal raw material which makes a supply source of an atom Mforming a constituent of the crystal of the piezoelectric ceramic material to be grown, and a second metal raw material which makes a supply source of an atom Mforming a constituent of the crystal of the piezoelectric ceramic material to be grown.</p> |
