“…This is the reason for the yellow-green color of the specimens. At 633 nm, the highest transmittance is approximately 32%, which is about two times of the value previously reported in similar PZ-PT-PZN system by Y. J. Wu et al [10].…”

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.

“…[134,135] Moreover, SPS has been also used as a new method of preparing transparent xPb(Zn 1/3 Nb 2/3 )O 3 -yPbZrO 3 -(1 À x À y)PbTiO 3 ceramics that could be promising candidates for applications in areas such as electro-optics and pyro-optics. [136] A result of great importance to be highlighted is the successful use of the combination of mechanosynthesis and SPS for the preparation of nanostructured 0.92PbZn 1/3 -Nb 2/3 O 3 -0.08PbTiO 3 ceramics. This approach allows the PZN-PT perovskite to be stabilized and, at the same time, grain growth to be controlled.…”

“…[17][18][19][20][21] The process has been used to produce transparent polycrystalline ceramics such as AlN with grain size of about 5 lm, [22] nanometric MgO with grain size around 50 nm, [23] and lead zirconates and titanates. [24] In a previous work we have shown that the coupling of the fast field-activated sintering technique with high pressure (up to 1 GPa), further enhances the feasibility of obtaining fully-dense materials with grain size in the nanometric range [25] and characterized by a high level of transparency. These results can be obtained using very short sintering cycles starting with commercial powders.…”

Transparent samples of cubic (8 mol % yttria) and tetragonal (3 mol % yttria) zirconia were prepared from nanometric powders by the pulsed electric current sintering process. The crystallite size of the resulting dense samples was about 50 nm in both cases. The consolidation pressure had a positive effect on the occurrence of transparency for both modifications. Transmittance in the near infrared for 1 mm thick samples is above the 60 % for the cubic (8 %YSZ) and above 50 % for the tetragonal (3 % YSZ) zirconia, representing between 70 and 80 % of the theoretical values of the two modifications. Samples had a yellowish‐brown coloration which was attributed to the presence of color centers. Annealing in oxygen improved transmittance initially, but prolonged annealing resulted in translucent samples. The role of porosity in transmittance is analyzed.
