Aging of ceramic capacitors

Ceramic capacitors with high dielectric constant mostly consist of barium titanate (BaTiO3).
When capacitors heated above the temperature of their Curie point they lose their capacitance over time. This process is known as aging.
Curie point is the temperature at which the crystal structure changes along with disappearance of spontaneous polarization ...
