Abstract
The transmission electron microscope (TEM) was used to directly observe ordered microdomains in Pb(Sc0.5Ta0.5)O3 (PST). The microstructure of both single crystal and polycrystalline PST was studied as a function of S, the degree of order (which was controlled by thermal treatment). The observed domain sizes were in good agreement with the results of prior X-ray studies. It was found that the domain coarsening kinetics are much slower for the single crystal than the polycrystalline material. Also evidence was obtained for the presence of short range order within PST.Keywords
