Abstract

PROCEDIMIENTO PARA LA PREPARACION DE MATERIALES CERAMICOS PIEZOELECTRICOS DE PZTN MEDIANTE LA ADICION A UNA CHAMOTA DE OXIDOS CALCINADA DE HASTA UN 5% EN PESO DE UN COPRECIPITADO DE HIDROXIDOS DE LA MISMA COMPOSICION QUE LA CHAMOTA Y CON LA MISMA RELACION ESTEQUIOMETRICA ENTRE LOS METALES CONSTITUYENTES QUE LA EXISTENTE EN LA CHAMOTA. LOS OXIDOS CONSTITUYENTES DE LA CHAMOTA SON PBO, ZROSI2, TIOSI2, Y NBSI2OSI5. EL MATERIAL PZTN ASI OBTENIDO RESPONDE A LA FORMULA BASICA: PB(TISI0.47 ZRSI0.53)OSI3 + 0.015 NB*C ESTE MATERIAL SINTERIZADO A UNA TEMPERATURA DE 1.000º A 1.125º C Y POLARIZADO POSEE BUENAS PROPIEDADES DIELECTRICAS Y PIEZOELECTRICAS, ALTA TEMPERATURA DE CURIE Y ES ADECUADO PARA LA FABRICACION DE IGNITORES, RESONADORES Y TRANSDUCTORES SONICOS Y ULTRASONICOS.
