Abstract
Grain size effects in polycrystalline BaTiO3 are reviewed in terms of the “internal stress model”. By considering polarization dependent terms in the Devonshire free energy expression, the dielectric constant may be calculated for the whole ferroelectric temperature region, under various stress systems. Encouraging comparisons with measured values may be made.Keywords
