A PROCESS FOR SYNTHESIS FO PMN-PT PIEZOELECTRIC AND ELECTROSTRICTEVE CERAMICS FREE FORM DETRIMENTAL PYROCHLORE PHASE FOR SMART SENSORS AND ACTUATORS;

摘要

Present invention provides the method for the preparation of ferroelectric Lead Magnesium Niobate-Lead Titanate (PMN-PT) ceramic solid solution system free from pyrochlore phase and having high dielectric and piezoelectric properties and enhancing the reactivity of the constituents to achieve chemical homogeneity and stoichiometry in the sintered ceramics.
