Properties of Ceramics
There is a sudden increase seen in the expansion coefficient in the temperature range of 550°C to 600°C. At this temperature range a structural rearrangement takes place in which a glassy solid transforms to a supercooled liquid. Above this temperature range viscous flow takes place and the sample contracts.
