Flash sintering of lead zirconate titanate ceramics under …
The rapid heating during flash sintering is also an important reason for the rapid densification of the ceramics. High-voltage flashover and oxidative heat release from the surface spherical material may trigger flash sintering in air. This study provides a rapid sintering method for PZT ceramics that can save energy and reduce environmental ...
