ABSTRACT:
A method for preparing oxide piezoelectric material wafers from a rhombohedral single crystal of an oxide piezoelectric material as-grown cylindrically in the X-axis direction includes linearly rubbing-off at least one side portion of such as-grown cylindrical single crystal facing to a specified direction along the longitudinal direction of such single crystal before cutting X-cut wafers from such single crystal thereby to provide a corresponding flat portion.
