1.

A study was made of the technological characteristics of a process for the preparation of ferromolybdenum alloy powder, in which mixtures of Fe3O4 and MoO3 oxides are subjected to ferritization and subsequent direct reduction.



2.

For compacted mixtures containing up to 1.5% MoO3, complete solid-phase ferritization is achieved. The optimum process parameters are a temperature of 900°C and a process duration of 6–9 h.



3.

To obtain a complex Fe3O4-MoO3-base oxide from mixtures with MoO3 contents of 1.5–10.5% or higher, another process is proposed, in which the ammonium chloride NH4Cl is added to the mixture to accelerate ferritization.



4.

The optimum process parameters have been determined for the ferritization of complex Fe3O4-MoO3 oxides, and some test results are reported. The new method may be applied to the preparation of ferrites, complex composite powders, and dispersion-hardening alloys.
