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. SrTiO3 single crystal is also widely used for special optical windows and as a high-quality sputtering target.
MTI has a full production line to manufacture high-purity SrTiO3 powder, single crystal boules, and EPI-polished substrates in many sizes.
