Strontium barium niobate

Strontium barium niobate is the chemical compound Sr_xBa_1-xNb₂O₆ for 0.32≤x≤0.82.

Strontium Barium Niobate is a ferroelectric material commonly used in single crystal form in electro-optics, acousto-optics, and photorefractive non-linear optics for its photorefractive properties.

Strontium Barium Niobate is one of the few tetragonal tungsten bronze compounds without volatile elements making it a useful system for probing structure-property relations. Strontium Barium Niobate is a normal ferroelectric for Barium-rich compositions and becomes a relaxor ferroelectric with increasing strontium content. This as been attributed to positional disorder of the A-site cations alongside incommensurate oxygen octahedral tilting
