Abstract: The object of the research is the intriguing and versatile material known as coal that attracted a lot of attention lately because of its potential use in a variety of fields, including cutting-edge building materials, environmental remediation methods, and creative energy storage solutions. This study presents an extensive characterization of Algerian natural coal powders, employing a multifaceted analytical approach that includes Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Raman Spectroscopy, to reveal their physicochemical properties including morphology, particle size distribution, crystalline structure, and functional groups.The SEM analysis unveiled a heterogeneous morphology with a broad particle size distribution, indicative of the coal's complex structure. The XRD findings, refined using Rietveld analysis, distinguish Carbon (C) and Silicon Dioxide (SiO2) as the primary phases, with crystallite sizes measuring 18.7539 nm for C and 16.6291 nm for SiO2. These phases constitute 98.8 % and 12 % of the composition, respectively, while the presence of quartz underscores the coal’s geological background and its thermal resilience.Regarding the results of the FTIR spectroscopy, absorption peaks corresponding to various functional groups are highlighted, suggesting a rich organic and inorganic composition. Raman spectroscopy corroborates the presence of disordered and graphitic carbon structures, emphasizing the coal's potential for diverse applications. These findings underline the significance of Algerian coal powders for environmental remediation, energy storage, and advanced construction materials, contributing to the advancement of sustainable energy solutions.
