Theoretical Density and PbO Deficiency of Pore-Free Transparent PLZT Ceramics

Preparation and characterization of transparent PZN–PLZT ceramics

Transparent Pb(Zn1/3Nb2/3)O3–(Pb1-xLax)(Zr1-yTiy)O3 (PZN–PLZT) ferroelectric ceramics have successfully been prepared by hot-pressed sintering in oxygen atmosphere. Uniform cylindrical samples with diameter as large as 50 mm can readily be obtained. X-ray analysis and scanning electron microscopy experiments showed a pure perovskite phase, thin grain boundaries, and uniform dense microstructure...

Influence of Ceramic Technology on the Microstructure and Ferroelectric Properties of Transparent Plzt Ceramics

Mixed-oxides and the coprecipitation procedure were used to prepare PLZT x/65/35 powders. Transparent samples were obtained by hot-pressing. The influence of processing parameters on the microstructure and electrical properties was studied.

Microstructure of Transparent Strontium Fresnoite Glass-Ceramics

Glass-ceramics grown from a glass of the composition Sr2TiSi2.45O8.9 (STS 45) are analyzed by scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD). Oriented nucleation with the c-axes preferably perpendicular to the surface is detected. A very strong 001-texture is observed after only 10 μm of growth into the bulk, making this the first system in which an orientation p...
