Outline of Final Research Achievements |
Spectrophotometric techniques including Raman and infrared spectroscopies enabled to characterize the domain structure in lead-free niobate piezoelectric materials, and confirmed that a permittivity increased significantly in the vicinity of domain walls. Based on the above fact, a manufacturing process was also improved successfully to synthesize the high-density ceramics having controlled microstructures, which could demonstrate excellent high-load resistances against elevated temperature and applied electrical field.
