• ABSTRACT: The challenge to develop high piezoelectric sensitivity and lead-free compositions ferroelectric ceramics has bring new interest to the study of some classical ferroelectrics as (Bi0.5Na0.5)TiO3 and its solid solutions. The composition near the MPB of the system (1-x) (Bi0.5Na0.5)TiO3-xBaTiO3 with x=0.06 (BNBT6) was found to have interesting properties as lead-free piezoelectric ceramic. Processing of ceramics from nanopowders allows getting fine grained, submicron structured, ceramics that are of interest both for the basic studies of size-effects in ferroelectrics and for their use as high frequency ultrasonic transducers. Submicron-structured BNBT6 ceramics, obtained from nanometric powder synthesized by sol gel auto-combustion at 500ºC, by hot-pressing at low temperature (700-800ºC) and subsequent recrystallization at higher temperature, still moderate (1100ºC), in order to reduce loss of the volatile elements, have been studied. Elastic and piezoelectric coefficients, as (literal)
