Strontium Titanate is a crystalline compound made of strontium and titanium, with the chemical formula SrTiO3. It is known for its high dielectric constant, making it useful in electronic applications, such as capacitors and insulators. The material can also exhibit ferroelectric properties, which means it can become polarized in an electric field. In addition to its electronic uses, strontium titanate is studied for its potential in photovoltaics and piezoelectric devices. Its unique optical properties allow it to be used in optical coatings and as a substrate for growing other materials, particularly in the field of thin-film technology.
