Abstract
"This investigation was carried out on several new, water soluble chemical precursors that were suitable for the preparation of transparent electrooptic PLZT 9/65/35 (La/Zr/Ti) ceramics. These new processes were compared to the standard alkoxide coprecipitation process with regard to chemical homogeneity, transparency, electrooptic activity, and electrical properties. The acetate precursors were the primary precursors utilized in this investigation of coprecipitation and pyrolysis techniques for the preparation of the PLZT powders. Evaluations were made on specimens that were hot pressed at 1175°C and 21.0 MPa for 6 hours and on specimens that were hot pressed at 1190°C and 21.0 MPa for 16 hours.
Experimental results showed that hot pressed samples from all the processes produced the following optimum results when hot pressed at 1190°C and 21.0 MPa for 16 hours: (1) optimum slim-loop ferroelectric hysteresis loops with no remanent polarization; (2) transmission curves similar to that of a standard 9/65/35 PLZT ceramic; and (3) hot pressed microstructures which showed a homogeneous crystalline phase with very clean, narrow grain boundaries (i.e., no second phases are along the grain boundaries)"--Abstract, page iii.
