Cromito de lantânio: Material para interconectores de células a combustível de óxido sólido - Uma revisão

Abstract

The lanthanum chromite (LaCrO 3) is a synthetic ceramic material, which has as main characteristics of good electrical conductivity at high temperatures (> 800°C), physical and chemical stability in oxidizing and reducing atmospheres, and a significant catalytic activity when used as powder. These features make it attractive for various technological applications such as catalysts, resistance to high temperature furnaces and electric power generation, and this field is potentially the most appropriate material for use as interconnector in Solid Oxide Fuel Cells (SOFC). The intrinsic characteristics, properties and processing of lanthanum chromite are detailed in this paper through a review of major studies reported over the past 40 years.
