Calcium Copper Titanate (CCTO) is an inorganic compound with the formula CaCu3Ti4O12. CCTO is a kind of ceramic dielectric material with a giant dielectric constant and low dielectric loss. It has a structure derived from the cubic perovskite structure by an octahedral tilting distortion as is GdFeO3.
CaCu₃Ti₄O₁₂ exhibits an anomalously high dielectric constant (ε≈10⁴-10⁵) and extremely low loss (tgδ≈0.03). Notably, the dielectric constant remains nearly unchanged over a wide temperature range (100-400K), reflecting high thermal stability in its dielectric response.

Why is CCTO high in dielectric constant?
CCTO has very high dielectric constant (10⁴-10⁵) at different frequencies and temperatures. It is because of its special crystal structure with heavy grain boundary effects and electron polarization.
Why are high dielectric constant materials important?
Dielectric constant controls the extent to which a material insulates and responds to electric fields. High values point towards better performance in electronics and telecoms.
How is CCTO powder prepared?
The traditional process is solid-state reaction:
Properties can be modified through changing preparation conditions or by dopants.
