      abstract     = {In this study, the equilibrium crystal shape (ECS) of a
                      model system, strontium titanate, is compared with the grain
                      boundary plane distribution (GBPD) as a function of
                      temperature. Strontium titanate has a pronounced surface
                      energy anisotropy and a grain growth anomaly, with the grain
                      growth rate decreasing by orders of magnitude with
                      increasing temperature. The ECS was determined from the
                      shape of small intragranular pores and the GBPD was
                      determined from orientation measurements on surfaces, with
                      the relative areas of grain boundary planes in a polycrystal
                      correlated to the surface energy of both adjacent crystal
                      planes. The grain boundary energy has been previously
                      proposed to be the sum of the surface energy of the adjacent
                      grains less a binding energy that is assumed to be constant.
                      While much experimental evidence exists for this assumption
                      at a fixed temperature, the influence of temperature is not
                      known. While the anisotropy of the ECS was found to decrease
                      with temperature, the anisotropy of the GBPD increased with
                      temperature. These findings indicate that changes in the
                      binding energy with temperature must be considered, as the
                      binding energy links the surface energy to the grain
                      boundary energy. The results are discussed with respect to
                      the grain growth anomaly of strontium titanate, in which the
                      grain growth decreases with increasing temperature.},
