Atmosphere assisted FLASH sintering of KNN
March 10-15, 2019
The use of FLASH alternative sintering technique allows a significant decrease in sintering time and temperature, contributing to the sustainable processing of high sintering temperature piezoelectrics. This is the case of potassium sodium niobate, K0.5Na0.5NbO3 (KNN), a relevant lead-free piezoelectric, which, due to alkali evaporation, is difficult to produce by conventional sintering, at T > 1100 ºC.
