A method for increasing the density of packaged micrometric powders. The method steps include filling a flexible container with a desired amount of micrometric powder, deaerating the flexible container and contained powder to remove substantially all air therein and achieve a desired vacuum, increasing the density of the contained micrometric powder to achieve a desired density and shape using a molding and at least one force concentrating device. The container includes a single layer of co-extruded polymeric material capable of achieving a hermetic seal even in the presence of an amount of powder contamination at the closure area. The level of vacuum may be chosen to achieve the desired malleability of the resulting compressed micrometric powder. Additional steps include sintering the densitized powder to remove substantially all impurities from the powder. |
