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.
Claims45
A process for the production of a metal product comprising subjecting a mixture of at least one reducible metal compound and at least one solid or liquid reducing agent to mechanical activation, said reducing agent being capable of reducing said reducible metal compound whereby the reducible metal compound is reduced by the reducing agent to provide the metal product.
A process for the production of a metal product which comprises subjecting at least one reducible metal compound to mechanical activation in an inert or reducing atmosphere for preventing the oxidation of said metal product;
- said mechanical activation of said metal compound being conducted in the presence of an additional gaseous reducing agent capable of reducing said metal compound.
