Abstract

polar PbTio3 ultrafine powders derived form Sol-Gel process is suspended in many liquid mediums by ultrasonic wave. In this paper, electric field-induced light transmission and scattering of PbTiO3 ultrafine powder suspension has been investigated. The effect of powder shapes, radius of powders, concentration of suspension and dispersion medium on light scattering and transmission is reported. The change of transmission light reaches 100, while for the scattering light reaches 30%. Electric field-induced change of refractive index of PbTiO3 powder suspensions has also been observed.
