About Strontium titanate
Strontium titanate (SrTiO3) is a crystalline solid that is often transparent or pale yellow. It possesses perovskite structure and has garnered significant attention in the field of materials science and solid-state physics due to its intriguing dielectric, ferroelectric, and optical properties. SrTiO3 is widely used as a substrate material for growing high-temperature superconductors, magnetic films, and other oxide thin films. Its high refractive index has also made it popular as a diamond simulant in jewelry, although this use has decreased in favor of more modern materials. In addition, it's used in electronics as a high-k dielectric in DRAM capacitors. The compound can be naturally found in a mineral called perovskite, but most commercial SrTiO3 is synthetically produced.
