摘要：
A series of Ce0.9Gd0.1O2-delta-Ni cermets with different Ni contents were prepared by conventional sintering process. The chemical compatibility between Ce0.9Gd0.1O2-delta (CGO) and Ni was investigated by X-ray diffraction, scanning electron microscopy, differential scanning calorimetry and X-ray photoelectron spectroscopy. Sintering and reduction temperatures of CGO-Ni cermets were also identified. Thermal expansion coefficients of the cermets were measured as a function of Ni content. No reaction or solid solubility between CGO and Ni was found. (C) 2007 Elsevier B.V. All rights reserved.
