This study comprehensively characterizes the physicochemical properties of Umuchieze kaolin clay using a suite of analytical techniques, including FTIR, SEM/EDS, TGA, and BET analyses. The FTIR results confirm a well-developed kaolinite structure, with distinct silicate framework vibrations in the low-frequency region (640–1163 cm?¹) and multiple O–H stretching bands in the high-frequency region (3620–3691 cm?¹), indicative of a highly ordered silicate matrix with variable hydroxyl environments. SEM/EDS analysis reveals a composition dominated by oxygen, silicon, and aluminium, consistent with the ideal kaolinite formula, while trace elements such as carbon, titanium, and iron are present at low levels. TGA demonstrates initial mass loss due to adsorbed water below 100?°C, stability up to 320?°C, and dehydroxylation peaking at 480?°C, after which a thermally stable metakaolin phase is formed. BET analysis indicates a moderate surface area (~23.76 m²/g) and an average pore diameter of ~25 nm, confirming a predominantly mesoporous structure. These findings underscore the material’s potential for high-quality paper production, environmental remediation, adsorption processes, and catalytic applications in oil and gas processes. Further studies are recommended to optimize surface modification and beneficiation techniques, thereby enhancing its performance in these advanced industrial applications.
