1. A downhole tool for use in a borehole, comprising:
a mandrel;
a sealing element comprising metal particles disposed about the mandrel; and
a piston to move a containment component of the downhole tool in an axial direction to move the metal particles in the axial direction, thereby displacing the metal particles in a radial direction toward a borehole wall to expand the sealing element in the radial direction to form a seal between the downhole tool and the borehole wall, wherein the containment component as deployed is configured to contact the borehole wall and axially contain the metal particles.
