ABSTRACT:
Method and apparatus for forming particles into shaped preforms by confining the loose particles in a shaped closure having at least one moveable side, subjecting each particle of the mass and at least a portion of the mold to an acceleration of a magnitude of at least 25 to 50 G's, and preferably in the range of 500 G's to 5000 G's, or greater, to generate at each particles a force causing such particle to impact with adjacent particles and form a homogeneous, fused article, and articles so formed.
