Abstract

A process for the production of a metal product which comprises subjecting a mixture of at least one reducible metal compound and at least one reducing agent to mechanical activation to produce a metal or alloy. Preferably, the mechanical activation is performed in an inert or reducing atmosphere. More than one reducing agent may be used. A ceramic material may be produced by including a nonmetal, or a compound which provides the nonmetal, into the starting materials. At least one other metal or a metalloid may be included in the starting materials for incorporation into the final product.
