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.
