Abstract
Piezoelectric materials have been highly difused in the past few years due to their properties; which can be used in many areas. Therefore is needed the development of piezoelectrics ceramics lead-free in order to replace Pb(ZrTi)O3 - PZT ceramics. This project seeks to develop ceramics with piezoelectric properties of the (K0,44Na0,52Li0,04)(Nb0,86Ta0,10Sb0,04)O3 system, KNL-NTS abbrevia…
