Material cerámico piezoeléctrico de alta temperatura de bisco3-pbtio3, diseñado químicamente para operar en condiciones de alta potencia y procedimiento para obtener dicho material cerámico

Abstract

[ES] Un material cerámico piezoeléctrico de alta temperatura de BiScO3-PbTiO3 diseñado químicamente para operar en condiciones de alta potencia, y un procedimiento para obtener dicho material cerámico. La invención se refiere a un material cerámico piezoeléctrico de alta temperatura de BiScO3-PbTiO3 y fórmula Bi0,36Pb0,64Sc0,36-xMnxTi0,64O3 en la que x oscila de 0,02 a 0,05, que incluye un defecto puntual bajo diseño para reducir significativamente las pérdidas dieléctricas y mecánicas. Además, la invención hace referencia a un procedimiento para obtener dicho material cerámico mediante sinterización convencional de polvos nanocristalinos sintetizados mediante la activación mecanoquímica de una mezcla estequiométrica de precursores.

[EN] The invention relates to a high temperature piezoelectric BiSc03-PbTi03 ceramic material of formula Bio.36Pbo.64Sco.36-xMnxTio.6403, wherein x ranges from 0.02 to 0.05, which includes a point defect engineering for strongly reduced dielectric and mechanical losses. Furthermore, the invention refers to a procedure for obtaining said ceramic material by conventional sintering of nanocrystalline powders synthesized by mechanochemical activation of a stoichiometric mixture of precursors.
