Abstract

In this study, raw materials composed of clay, laterite, and clinker were characterized in order to analyse their thermal and thermogravimetric behaviour and validate their use as heat storage materials in thermodynamic power plants. The raw materials were first ground (to a particle size of 100µm) and characterized using various methods (X-ray fluorescence spectrometry, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis) to better understand their different properties. This characterization made it possible to determine the various physicochemical properties of these raw materials. The aim is to make use of local materials such as clay, laterite from the Maradi region, and ash from the SONICHAR thermal power plant in order to develop new ceramic composite materials with good mechanical and thermal properties for use in thermodynamic power plants:
