What Is Copper calcium titanate CCTO

Calcium copper titanate, also known as CCTO, is a high dielectric constant inorganic energy storage material and one of the best materials for making super capacitors. The higher the dielectric constant of the dielectric material, the greater the energy that can be stored. CCTO has an abnormal giant dielectric constant and extremely low loss (tg δ ≈ 0.03), CCTO has high thermal stability, and the dielectric constant value remains unchanged in a wide temperature range (100~600K).
