General description
Strontium titanate (SrTiO3) is a crystalline oxide material known for its perovskite structure. It exhibits a high dielectric constant and is considered a promising material for various electronic applications. Strontium titanate has a density of 4.81 g/mL at 25 °C (lit.) and a melting point of about 2060°C. This compound is widely used in the production of capacitors, insulators, and piezoelectric devices due to its excellent dielectric properties. Additionally, strontium titanate is employed in the fabrication of thin films for advanced electronic devices, including transistors and sensors. Its unique optical properties also make it suitable for applications in photonics and optoelectronics.
