The Al203 particles are introduced into the AI-4wt.%Mg melt by the "vortex" method. After being cast, AI:Q-(AI-4wt.%Mg) composites are remelted at 700, 750, 800 and 850 Β°C for different residence times to investigate the formation of MgAI204 (spinel). The results show that MgAI204 is the unique int
Studies of the chemical preparation, surface area, pore distribution, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectra (XPS) and acid-base properties of magnesia-alumina composite oxides were carried out. The preparation method led to supports with high
