<p>The demand for sustainable ceramics with high thermal stability and wear resistance is increasing in advanced high-temperature industrial applications. This study aims to fabricate scoria-based ceramics as an eco-friendly material for high temperature and wear resistance applications. Therefore, a comprehensive study was conducted on the influence of scoria content and varying durations (2 and 4&#xa0;h) on the phase evolution, microstructure, mechanical and physical properties of ceramic samples fabricated from red clay and volcanic scoria at a low temperature of 950&#xa0;°C which has not been previously studied. The findings show that extending the sintering duration (4&#xa0;h) leads to the formation of a new dominant mineral phase accompanied by an increase in density reduced porosity and enhanced mechanical properties. Likewise, incorporating scoria accelerates the phase transformation process contributing to the development of finer grains and an enhanced glassy phase at prolonged sintering times, which in turn leads to higher hardness, wear resistance, and thermal stability. The findings demonstrate the potential of scoria-based ceramics as sustainable and cost effective materials with high performance and thermal stability for industrial applications at high temperatures, including refractory coatings, corrosion resistance, kiln linings, and thermal barriers.</p> Graphical Abstract <p></p>
