BaTiO₃ (BT) is a typical ferroelectric material used in capacitors. Various measurement methods have been deployed to study the relationship between particle size and structure and a compound's ferroelectricity. Among them, small angle / ultra-small angle X-ray scattering has been used to investigate the particle size of powder materials non-destructively, without dilution. Here the average particle size of a BT powder are evaluated by ultra-small angle X-ray scattering.
