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.

合成表面高度发达的镁热钼粉末

研究了在 600-750°C 的温度范围内，在动态真空条件（0.01 kPa）和 0.5-10 kPa 的残余氩气压力下，在反应器中用镁蒸气还原钼氧化物，从而合成表面高度发达的钼粉末。在 MgMoO4 和 CaMoO4 还原过程中，获得了比表面积高达 31.8 m2 g-1 的介孔钼粉。金属结晶的平均尺寸为 16-25 纳米。
