[1] 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.

[3] This has been attributed to positional disorder of the A-site cations [4] alongside incommensurate oxygen octahedral tilting [5] Strontium barium niobate is one of numerous ceramic materials that are known to exhibit abnormal grain growth, in which certain grains grow very large within a matrix of finer equiaxed grains.

This abnormal grain growth (AGG) has significant consequences on the dielectric and electronic performance of strontium barium niobate [6]
