KT Potassium Talate (KTaO3) Single crystal has a stable cubic structure, and can be used to make laser modulator, digital deflector and semiconductor devices. Due to the absence of phase transition in the temperature range from absolute zero to its melting point (1645K), and the good matching of its cell parameters with yttrium barium copper oxide superconductors, this crystal has the potential to be used as a substrate material for superconducting thin films
