Preparation and characterization of foamed ceramics from silicomanganese and fluorgypsum waste
High‐strength foamed ceramics were synthesized employing silicon‐manganese slag (SM) and fluorgypsum (FG) as raw materials, with SiC serving as the foaming agent. Investigations into the influence of firing temperature and FG content on the phase structure, microstructure, and physical properties of foam ceramics were conducted. Characterization of the samples was performed through X‐ray diffraction and scanning electron microscopy. Results indicate that an increase in FG content lowers the matrix melting point, promotes crystal growth, enhances compressive strength, and forms a uniform pore structure. At an FG content of 11%, ceramics prepared at a firing temperature of 1130°C exhibit a density of 0.56 g/cm3, porosity of 78.45%, and compressive strength of 3.05 MPa. This study explores the use of FG as a cost‐effective alternative to borax, demonstrating a sustainable approach for foam ceramics preparation using silicomanganese slag and FG synergy.
