High dielectric constants have been found in oxides of the type ACu 3 Ti 4 O 12 . The most exceptional behavior is exhibited by CaCu 3 Ti 4 O 12 , which shows a dielectric constant at 1 kHz of about 12,000 that is nearly constant from room temperature to 3003C. The cubic structure of these materials
