| 摘要 |
The invention relates to a method of separating metal powder from a slurry of liquid metal and metal powder and salt, comprising introducing the slurry into a first vessel operated in an inert and/or vacuum environment for separation of liquid metal from the metal powder and salt leaving principally salt and metal powder substantially free of liquid metal, transferring the salt and metal powder to a second vessel operated in an inert environment, a transfer mechanism comprising a housing, a screw having a plurality of helical threads along a longitudinal shank within said housing for transferring material from said first vessel to said second vessel, and thereafter treating the salt and metal powder to produce passivated metal powder substantially free of salt and liquid metal, as pieces having diameters up to about five centimeters. The present invention is specially useful for separating Ti and alloys thereof. |
