More info

Potassium Tantalate (KTaO3) Crystal Substrate is a cubic-structured material with outstanding thermal and structural stability across a wide temperature range. It is widely used in laser modulation, digital beam deflection, and semiconductor applications. With no phase transitions from absolute zero to its melting point (1645K), KTaO3 offers excellent compatibility with yttrium barium copper oxide (YBCO) superconductors, making it a valuable substrate for superconducting thin films. Heeger Materials provides high-quality Potassium Tantalate Crystal Substrate to meet various research and industrial needs.
