The influences of different gravity levels on material diffusion and its microstructure during liquid phase sintering were discussed. The results show that the different phase segregation can occur under elevated gravity conditions. On the contrary, the multiphase ceramics with uniform distribution of different phases and well growth of AlN grains can be obtained in microgravity. Therefore, microgravity proves good conditions to fabricate improved materials. %K AlN-glass multiphase ceramics %K microgravity %K elevated gravity %K microstructure
