Abstract

The authors deal with the particle size dependence of the crystallographic structure and Curie/Neel temperature in powder samples. Ferroelectric Ba0.9Sr0.1TiO3 and antiferroelectric PbZrO3 were selected for this investigation. The phase transition temperature TC in the ferroelectric decreased with decreasing particle size, while TN in the antiferroelectric changed insensitively with particle size. This dependence may mainly be caused by the effective surface tensional stress estimated by P = 2γ/R, where γ is the surface tension (approximately 50-67 N/m) and R is the radius of the particle.
