Magnesiothermic Preparation of Molybdenum–Chromium Alloy Powders

  • Published:
Inorganic Materials Aims and scope

Abstract—

We have studied the process underlying the preparation of molybdenum–chromium alloy powders via the magnesium vapor reduction of the Cr2(MoO4)3 chromium molybdate in the temperature range from 700 to 800°C at residual argon pressures in the reactor from 5 to 15 kPa and obtained powders of Mo0.3Cr0.7 alloy, a mixture of Mo0.3Cr0.7 and Mo0.7Cr0.3 alloys, and alloys of a continuous series of MoхCr1 – х (0 < x < 1) solid solutions. The powders range in specific surface area from 33 to 48 m2/g and have a mesoporous structure.
