Abstract

The present work is devoted to the study of a dense and conductor material was prepared following an appropriate sintering of a low-cost local natural mineral (NM). Comprehensive morphological, textural, and microstructural characterizations were carried out in order to study the densification of NM samples shaped as thin layers obtained by casting method. It was found that sintering at 1000°C was enough to achieve densification without any change of material structure, as indicated by a decrease in specific surface area at a value of 3.50 m2 g-1. Furthermore, the effect of temperature on electrical conductivity was measured by impedance spectroscopy  under dry air by increasing temperatures starting from 400°C to obtain a conductivity value of 8.48 × 10-2 S cm-1  at 950°C. Such promising intrinsic electrical conductivity, in addition to appropriate material densification, paves the way for possible application of such a low-cost natural minerals as solid oxide electrolytes.

Keywords: Natural mineral, casting, electrical conductivity, dense electrolyte, solid oxide fuel cell
