This paper demonstrates the possibility of producing new red ceramics composites from red mud of hazardous bauxite waste (50?100 wt%), and foundry sand (10?50%) replacing the traditional clay-sand mix and preventing the environment pollution by such industrial wastes. The newly developed environment-friendly ceramics exhibit high physical properties (flexural strength, linear shrinkage, water absorption, and density). The ceramics? analysis by X-rays fluorescence, X-rays diffractometry, atom absorption spectroscopy, scanning electron microscopy, energy-dispersion spectroscopy, and laser micro-mass analysis revealed the synthesis of mainly glass-like structures with a small inclusion of crystalline structures. The values of flexural strength reached 10.54 MPa; after sintering at 1150 C, linear shrinkage varied between 6.62 and 7.92%, water absorption ? 2.77 and 14.41% and bulk density ? 1.65 and 2.07 g/cm3. The most valuable property of the developed materials is the ecological purity due to the heavy metal?s complete neutralization from both industrial wastes. |
