The master sintering curve (MSC) can sometimes be used for analyzing the shrinkage behaviour of ceramics. Densification of ␣-Al 2 O 3 with the mean particle size of 350 nm was continuously recorded during heating at 0.5, 2 and 5 • C/min. A MSC was successfully constructed using dilatometry data with
