In this paper, the mass fraction of

In this paper, the mass fraction of 25% Al2O3 powder and the mass fraction of 75% Al powder was mixed in the blender, mixer speed 100r/min, mixing time of 3.5h, forming, sintering and a series of processes for preparing the alumina/aluminum metallic ceramic materials, through performance testing and analysis can be found the density of the sample first increased and then decreased with the increase of sintering temperature, a melting point close to the sintering temperature and sintering, the density of the cermet can be made relatively high. When the sintering temperature is of 600°C and 700°C, the macro performance of sample is better. The cermet is sintered at 700°C, its microstructure is relatively better.
