Strontium barium niobate
Strontium barium niobate is the chemical compound SrxBa1−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 has been attributed to positional disorder of the A-site cations alongside incommensurate oxygen octahedral tilting
