Title
Modeling of Joule heating in KNN FLASH sintering
Conference Dates
March 10-15, 2019
Abstract
In this work, we propose the use of FLASH sintering as an alternative technique to densify Potassium Sodium Niobate, K0.5Na0.5NbO3, KNN, a piezoceramic with relevant promising applications and a possible viable substitute of lead zirconate titanate based compositions (Pb1-x ZrxTiO3, PZT). We aim to increase this material performance by densifying KNN ceramics without secondary phase segregation. Furthermore, FLASH will contribute to a more sustainable processing of piezoelectrics as lead-free ceramics at reduced sintering temperature and time.
