| Abstract Scope |
In the present work, we synthetized a ceramic material, InCr1−xTixO3+x/2 (x = 2/6, 2/7, and 1/4) which structure belongs to a modulated group with Cr(III) in a coordination number (CN) 5, whose cation can also be substituted by Ti(IV). X-ray Powder Diffraction (XRD) was used to identify the formation of the monoclinic phase and the least squares method to obtain lattice parameters. The microstructure was characterized by Scanning Electron Microscopy (SEM) and the ratio weight/volume to know the apparent densification of the pellets with the applied sintering process. Dielectric behavior from room temperature up to 450 oC shows a relaxation process as the Ti(IV) is introduced in the solid solution. The combined presence of cations in different CN and valence state seems to be responsible for the high dielectric loses as Cr is replaced by Ti ions. |
