SUSTAINABLE DEVELOPMENT OF SHOUSHAN STONE WASTE IN GLAZE MATERIALS: STUDY ON COLORATION MECHANISM AND DURABILITY

This study focuses on the sustainable utilization of shoushan stone mineral processing waste in glaze materials, exploring its synergistic effects on regulating the coloration mechanism and optimizing glaze layer performance. Through single-factor experiments, the impact of varying shoushan stone incorporation levels on ceramic properties was systematically analyzed. Techniques such as XRD, SEM, EDS, and XPS were employed to investigate the effects of shoushan stone on glaze layer structure, Cu ion valence states, and color performance. The results demonstrate that incorporating 10 wt. % shoushan stone significantly enhances the density and glossiness of the glaze layer, promotes the stable presence of Cu⁺, and induces phase separation structures, thereby improving the color purity and stability of blue glazes. Physicochemical performance tests indicate that the glaze layer exhibits excellent thermal shock resistance, mechanical strength, and environmental friendliness. The SiO₂, Al₂O₃, K₂O, and CaO abundant in shoushan stone provide superior fluxing and network regulation effects, confirming its feasibility as a blue glaze raw material. This study presents a novel approach to the high-value utilization of mineral waste, with significant theoretical and practical implications for the sustainable manufacturing of ceramic glazes.
