Magnesium vapor reduction of complex double compounds of molybdenum with tungsten

The process of obtaining powder of the Mo-W alloy by magnesium vapor reduction of MgWxMo1-xO4 and CaWxMo1-xO4 oxide compounds (x = 0.3) with a residual inert gas pressure of 2-20 kPa in the temperature range 700-800°C was investigated. Argon or helium was used as an inert gas. Powders of Mo-W alloy...

Description
Summary:The process of obtaining powder of the Mo-W alloy by magnesium vapor reduction of MgWxMo1-xO4 and CaWxMo1-xO4 oxide compounds (x = 0.3) with a residual inert gas pressure of 2-20 kPa in the temperature range 700-800°C was investigated. Argon or helium was used as an inert gas. Powders of Mo-W alloy with a specific surface area of up to 20 m2g-1 were obtained. When both types of compounds were reduced at a residual pressure in the reactor of more than 5 kPa, spatial separation of the reaction products was observed with removal of magnesium oxide from the reaction zone.
