Resumo

We have studied the process underlying the preparation of highly disperse tungsten + chromium powders via the magnesium vapor reduction of tungsten and chromium mixed oxide compounds in the temperature range from 700 to 800°C at residual argon pressures in the reactor from 5 to 20 kPa and obtained W + Cr powder mixtures with specific surface area from 34 to 49 m2/g. The powders have a mesoporous structure and can be used as precursors for the preparation of self-passivating alloys.
