Abstract
The synthesis of molybdenum powders with a highly developed surface by reducing molybdenum oxides with magnesium vapor in the temperature range of 600–750°C under dynamic vacuum conditions (0.01 kPa) and residual argon pressure of 0.5–10 kPa in a reactor is studied. During the MgMoO4 and CaMoO4 reduction, mesoporous molybdenum powders with a specific surface area of up to 31.8 m2 g–1 are obtained. The average size of the metal crystallites is 16–25 nm.
