Abstract
A simple and effective method for the synthesis of nano-crystalline PZT spatulae has been re-ported near MPB via a new Solution-Ignition Synthesis route and has been characterized by FT-IR, XRD, TG/DTG/DTA and SEM techniques. X-ray line broadening and Scherrer formula show crystallite size to be~20 nm. Densities of nano-crystalline spatulae of PZT in pellet form made by using 2% PVA and without PVA have been found to be 5.35 and 7.51 gm/cm3 respec-tively compared to the theoretical value of 7.78 gm/cm3. Dielectric constants of 83 and 227 of these spatulae with dielectric loss 0.118 and 0.0609 at 1 MHz and a high resistivity value of 3.043 * 107 Ω cm for PZT pellets made without PVA suggest these nano-crystalline PZT spatu-lae to be the potential candidates for high fre-quency applications.
