SrTiO3 (111)+/-0.1 deg 10x10x0.5mm, 1sp, (Crystal made in Japan)

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..

SrTiO3 was grown by vernue ( flame ) method , which is not easy to get perfect crystalline.   The SrTiO3 made in Japan usually has better quality than other manufacturees
