product details

Potassium tantalate KTaO3 substrate


Potassium tantalate, KTaO3 substrate, KTaO3 single crystal is a novel crystal having a perovskite structure and pyrochlore, has broad market prospects in superconducting thin film applications. We can offer a variety sizes of KTaO3 single-crystal substrate. Can be used to produce a laser modulator, a digital-type deflector and semiconductor devices. 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 ,
