Die Technology and Construction for Compacting Gas-Saturated Tungsten and Carbon Powders

Abstract

Analysis is provided for known and new technology and construction of dies for molding gas-saturated powders of tungsten and carbon powder composites made on the basis of YuUrGU scientist inventions. Gas saturation of tungsten powder is connected with the unusually low bulk density equal to 0.06–0.12 of the density of pore-free tungsten, and small powder particle size within the limits of 1–3 μm. High gas saturation of powder composites based on carbon is determined by the high capacity of carbon for adsorption of gas and liquid vapor molecules at particle surfaces.
