초록
MgAl2O4-Ti (C, N) composites were synthesized through aluminothermic-carbothermal reduction and molten salts synthesis (MSS) routes in coke bed conditions. The phases were characterized using X-ray diffraction (XRD) and microstructures of composites were investigated by scanning electron microscopy (SEM). The results showed that the synthesis temperature of MgAl2O4-Ti (C, N) was decreased about 300 o C in MSS method in comparison with aluminothermic-carbothermal reduction. The KCl and NaCl salts proved better transportation path for reactant species and accelerate composite formation and also establish the microstructure with homogenous and fine grains.
