SrTiO3 Strontium titanate single crystal has the good lattice structure possessed by perovskite structured materials. It is an excellent substrate material for the epitaxial growth of HTS and most oxide films, and has been widely used in the research of high-temperature superconducting films. It is also widely used in special optical windows and high-quality sputtering targets.
