KTaO3 Crystal Substrate
KTaO3 Single Crystal is a novel crystal having a perovskite structure and pyrochlore, has broad market prospects in superconducting thin film applications. Since the KTaO3 Crystals from the absolute zero to its melting point (1645K) no phase change, and the unit cell parameters good match with superconductor YBCO.
