IN305672: A method of tape casting KNN for making pilezoelectric wafers and multilayer actuators
Abstract
The invention relates to an improved method for the preparation of KNN tapes useful for making piezoelectric wafers and multilayer actuators. The invention provides a method of tape casting potassium sodium niobate (KNN) for making piezoelectric wafers and multilayer actuators. The invented method provides the selection and optimization of proper dispersant and processing variables necessary for successful tape casting. The method provides a scope for making lead-free environment-friendly piezo wafers and multilayers. The piezo tapes fabricated by this method after sintering showed satisfactory dielectric and piezoelectric properties.
