摘要： To provide a completely novel piezoelectric ceramic having an alkali-containing niobate-based perovskite structure in which constituent elements are Li, Na, K, Nb, and O, wherein sintering can be readily performed at about 1000°C and wherein piezoelectric characteristics are not significantly reduced.
A Li 3 NbO 4 crystal phase is intentionally deposited on a piezoelectric ceramic having an alkali-containing niobate-based perovskite structure in which constituent elements are Li, Na, K, Nb, and O, whereby sintering becomes possible at about 1000°C rather than at the normally required sintering temperature of 1050°C or greater.

摘要： An elastic surface wave apparatus includes a substrate (10), a pair of reflection electrodes (14, 18) formed on the substrate, and a plurality of drive electrodes (12) formed so as to be sandwiched by the pair of reflection electrodes. Cycle of each of the reflection electrodes changes according to a predetermined change pattern. Thus, it is possible to simultaneously improve suppression of spurious wave and squareness characteristics (precipitous shoulder portion of a passing zone).
