چکیده
|
Nano-ceramic pb0.96la0.04fe0.03ti0.97o3 (pl4f3t) was prepared by sol-gel reaction method. raman and xrd patterns of pl4f3t ceramic showed that a single-phase was formed exhibiting a pseudo-cubic crystal structure. with sem,we examined the micro-structural properties. the electrical behavior was investigated by the impedance spectroscopy in the range of 50°c - 600°c. this study was carried out by analysis of the complex impedance (z*) from the measurement range of 1 khz to 1 mhz. complex analysis provides wider information related to charge transport processes.
