SrTiO₃ single crystal provides a good lattice match to most materials with a 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 for manufacturing high-purity SrTiO₃ powder, single crystal boules, and EPI-polished substrates in many sizes.

Note: SrTiO₃ is grown by the Verneuil flame-fusion method. Crystal perfection may therefore vary between substrates, and the rocking curve may differ from substrate to substrate. Please inspect the SrTiO₃ substrate before growth.

XRD is not routinely performed on every substrate in order to keep costs low. If rocking-curve measurement is required, please request it before ordering. Additional charges may apply.
