Abstract
In the process of particle settling in a dilute, a density graded distribution of the liquid below the suspension needs to be designed according to the gravity of the suspension prior to sedimentation. In the present paper a compositionally graded W-Mo composite was formed via the settling of the W and Mo particles, with a density gradient distributed in the initial clear liquid along the settling direction.
