Normativas para la caracterización de cerámicas piezoelectricas

Abstract
espanolEl desarrollo de materiales ceramicos piezoelectricos lleva consigo la obligada caracterizacion de los mismos. Para llevar a cabo dicha caracterizacion, existen una serie de guias internacionalmente admitidas, reunidas en Normas de diversos organismos. El objetivo del trabajo es mostrar las diferencias entre las distintas Normativas ya establecidas, reuniendolas en tres grupos: Normativas de material. Normativas de componentes y Normativas de sistemas. A lo largo del trabajo se intentan justificar las variaciones que han ido surgiendo desde la primera norma, dictada en 1945. Asimismo, como ejemplo, se describe lo normalizado sobre dos parametros decisivos: a^^ y Q EnglishThe development of piezoelectric ceramic materials involve their characterization at the end of the process. To make such a characterization , a set of International Piezoelectric Standards can be used. Nevertheless, there exist different test criteria between the publications from the different International Organisms. This paper is a review of the published Standards having as goal to show the differences between them. To do that, a classification in three different —groups material, component and device standards— is firstly made. In the paper, the variations in the standards recommendations from 1945 has been searched and justifyed. More specifically, the measuring procedures for djj and Q^ are explained in relation with the progress on materials and instrumentation from the first standard report
