Abstract The challenge in creating stable and dense KNbO 3 ceramics is suppressing the K 2 O volatility that occurs at elevated temperature and avoiding the formation of unwanted phases. This challenge could be addressed by applying a field-assisted sintering technique. Flash sintering was conducted successfully on KNbO 3 powder, under applied electric field of 600 V/cm at 750 °C. The linear shrinkage of the sample was approximately 18%, and its density was 95% of the theoretical density… CONTINUE READING
