Barium Strontium Titanate (BST)

Barium Strontium Titanate, also known as BST sees wide use in DRAM (Dynamic Random Access Memory) Systems, ceramic capacitors, and infrared detectors. The material’s high dielectric constant, combined with optimal charge storage density compared to Silicon Dioxide (SiO2) makes it a promising candidate to replace current dielectric materials. Barium Strontium Titanate exhibits ferroelectric properties, meaning it has a spontaneous electric polarization that can be reversed by the application of an external electric field. Research continues to reveal the unique uses of this ceramic material. Additionally, Barium Strontium Titanate undergoes phase transitions at certain temperatures which can alter its electrical properties. This transition is temperature-dependent and is influenced by the Ba/Sr ratio. BST can also be used as a non-linear optical material due to its ability to change its refractive index in response to an electrical field.
