Strontium titanate  (SrTiO3) single crystal provides a good lattice match to most materials with Perovskite structure. It is an excellent substrate for epitaxial growth of HTS and many oxide thin films. Strontium titanate single crystal has also been used widely for special optical windows and as high quality sputtering target. The large diameter of  Strontium titanate (SrTiO3) crystal can reachφ35mm。
