To address the limitations of conventional carbothermal reduction methods—including impurity contamination from organic carbon sources, inadequate reaction stability, and the paucity of research on the oxidation behavior and biphase synergistic mechanisms of SiC–ZrC composite powders—this study developed a novel controlled carbothermal reduction process using high-purity graphite as the carbon source (argon atmosphere, 1400–1600<!--> <!-->°C).

The 50 raw clays from Serbia were grouped using Principal Components Analysis (PCA) according to compositional similarities, and these classifications were subsequently compared against industrial samples. Further analysis through mineralogical composition and behavior during heating within these groups provided a comprehensive understanding of their physical behavior. The results demonstrate that PCA effectively distinguishes raw clays based on their chemical composition, paving the way for a reliable classification for ceramic production.
