The effect of gravity on the liquid phase sintering was analysed and investigated with Al-Cu and Al-Fe systems. The effect of gravity on the capillary phenomenon in the rearrangement stage of the liquid phase sintering of the used systems was not detected distinctly. The measured rates of sedimentation of solid particles in the liquid metal was less than calculated values. This fact suggests that the convection effect of the liquid metal should be taken into account in the calculation. It was concluded that the system having the melting point difference larger than 500℃ and the density difference larger than 10g/cm^3 should be used to reveal the effect of gravity on the liquid phase sintering.
