Using of textured polycrystalline SbSI in actuators

This paper presents the design and fabrication of a light deflector made from textured polycrystalline antimony sulfoiodide (SbSI) obtained by gradient freezing during the rapid quenching from the liquid state. The piezoelectric and electrostriction parameters of the textured polycrystalline SbSI are evaluated from the reflection measurements. First time the electrostrictive constant of this material (4.6(1)×10−13m2/V2) is reported.
