Due to recent environmental issues, many research findings on non‐lead‐based materials have appeared. The author also reported the possibility of improvement of piezoelectric materials by microwave (MW) sintering. We checked the relationships between the domain size and piezoelectric constant d 33 in BaTiO 3 ceramics, and the grain boundary and domain properties of ceramics, which are reported herein. © 2012 Wiley Periodicals, Inc.
