This report evaluates the material properties of kenyaite—a layered sodium silicate with high potential for practical applications—and silica glass sludge, an industrial byproduct, to advance sustainable material engineering and resource recycling. Through X-ray diffraction (XRD) structural analysis, this study investigates the structural stability of kenyaite under mechanical pressing into pellets and confirms the amorphous nature of silica glass sludge, which mitigates inhalation-related health risks. Furthermore, the crystallization behavior and physicochemical responses of these materials under high-temperature heat treatment and in contact with alkali metal impurities are explored to determine their viability for industrial utilization.
