文摘

The influence of Ni doped on the morphology and dielectric properties of CaCu3Ti4O12. Composition with formula CaCu3-xNixTi4O12 (0 ≤ x = 0.2) is prepared by a conventional solid solution. In all compositions, structure is remained cubic. The dielectric constant in CCTO strongly depends on the grain size. Interesting dielectric properties.
