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 has also been used widely for special optical windows and as high quality sputtering target.
MTI has the full production line to manufacture first the high purity SrTiO3 powder, then the single crystal boules and finally the epi-polished substrates in many sizes.
This allows us to provide SrTiO3 single crystal products with the highest quality and the lowest price to our customers all over the world.
