Production of tungsten powders with highly developed surface
The process of producing tungsten powders with a highly developed surface by reducing its oxide compounds with magnesium vapor in the temperature range 600—750 °C under dynamic vacuum (0.01 kPa) and with a residual argon pressure in the reactor 0.5—10 kPa has been studied. During the reduction of magnesium and calcium tungstates, tungsten powders were obtained with a specific surface area of 40 m2·g–1, characterized by a mesoporous structure.
