摘要：

The synthesis of forsterite-based ceramic nanopowders using sol-gel method assisted by further thermal treatment has been performed. X-ray diffraction and SEM analysis of the obtained nanopowders are presented. Detailed impedance spectroscopy study of the forsterite nanoceramics doped with Cr3+, Y3+ and Zr4+ ions has been carried out. Impedance spectra are interpreted in terms of equivalent circuits. Peculiarities of the electrical properties for each of the materials under study are discussed. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
