In this paper, to reduce the cost of production of parts by injection molding technology of metal powder mixtures (MIM technology), it is proposed to use metal powder mixtures (feedstock) with high fluidity for the manufacture of green parts. High fluidity is achieved by increasing the proportion of paraffin wax in the binder. This can significantly reduce the pressing pressure when pressing ...

Particle Sizes. The size of contaminants and particles are usually described in microns, a metric unit of measure where. one micron is one-millionth of a meter. 1 micron = 10-6 m = 1 μm. In imperial units. 1 inch = 25400 microns. 1 micron = 1 / 25400 inch. The eye can in general see particles larger than …
Abstract. The Darex process developed for ihe recovery of U from stainless steel- containing reactor fuels consists of dissolution of the fuel material in dilute aqua regia, removal of chloride from the solution to prevent corrosion of downstream stainless steel process equipment, and adjustment of the nitrate solution to solvent extraction feed conditions.
