0.3Pb(Zn 1/3 Nb 2/3 )O 3 -0.7Pb 0.96 La 0.4 (Zr x Ti 1-x )O 3 (PZN-PLZT, x = 0.5∼⃒0.53) transparent piezoelectric ceramics with high density and pure perovskite have been synthesized by a two-stage hot-pressing procedure. The bulk densities of the specimens were measured by Archimedes method, and they are very close (> 99%) to the theoretical density. With the Zr/Ti ratios varying from 50/50 to 53/47, the d 33 and k p show an ascending and descending trend, namely a peak of piezoelectric properties. The maximum of d 33 and k p are 845pC/N and 0.70, respectively. The transmittances of the specimens were tested at the wavelength ranging from 300 nm to 800 nm. The transmittance of the specimens was enhanced with the increase of the wavelength. And the specimens with Zr/Ti = 52.5/47.5 have maximum transmittance. Transparence and high piezoelectric properties of PZN-PLZT brighten its application in optical and electrical devices. [ABSTRACT FROM AUTHOR] |
