Abstract
The phase transition behaviour of lead scandium tantalate is discussed and the variation of this behaviour with the degree of long-range order is considered. Using the model of Diamond (1960),1 curves for dielectric constant and spontaneous polarisation are calculated, and a comparison with experimental results made. Good agreement is found. Expressions are given which allow these curves to be calculated for any given degree of long-range order.Keywords
