✦ Synopsis


In this work, single-phase cubic perovskite CaCu 3 Ti 4 O 12 powders have been synthesized successfully by microwave heating with a relatively low energy consumption and short time, compared with conventional synthesis. The reaction evolution of forming CCTO has been suggested according to the XRD data. The ceramics from microwave-synthesized powder was found to have higher dielectric constant than that from conventional synthesized powder under the same sintering conditions.

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.
