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 d
CaCu 3 Ti 4 À x Fe x O 12 (0 rx r 0.2) ceramics were fabricated by a solid-state reaction method, and the dielectric properties were studied. Dielectric measurement performed at room temperature shows that with Fe content increasing from 0 to 0.2, the dielectric constant (e 0 ) decreases from about
