loss tangent at 10 GHz = ~5 × 10^-4 (300 K), ~3 × 10^-4 (77 K)

Single crystal strontium titanate substrate lattice has a good lattice match with most perovskite structured materials. It is an excellent substrate from the epitaxial growth of many oxide this films and high-temperature superconductors. It also has applications in optical windows and as a high-quality sputtering target.
