Abstract:
A novel ceramic was prepared from red mud by designing its composition of the CaO-MgO (10wt.%) -SiO2-Al2O3 system. Linear shrinkage, bulk density, water absorption and bending strength of the ceramics were tested. Crystal phases and microstructure of raw materials and ceramic samples were respectively analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that all ceramic samples (replace of red mud for low quality clay from 10wt.%-30wt.%) have the similar thermal behavior, crystal phases and physical and mechanical properties, including low water absorption of about 0.07% and high blending strength of about 127.39MPa. Its sufficient densification during sintering process and generation of a great amount of pyroxene phase in ceramics would contribute to excellent mechanical properties.
