The direct write technology provides an interesting opportunity for plugging blind via holes as a more precise alternative to currently used screen printing processes. This technology provides a complete, void-less filling of the via and fabrication of the interconnects extending from the via in one single step. After deposition, the material is heat treated (sintered) to densify into a highly ...

Fast ion conducting garnet materials have been identified as promising electrolytes for all solid-state batteries. However, reliable synthetic routes to materials with fully elucidated cation site occupancies where an enhancement in lithium conductivity is observed remains a challenge. Ca-Incorporation is developed here as a promising approach to enhance the ionic conductivity of garnet-type Li...

The vitrification of an hazardous iron-rich waste (W), arising from slag flotation of copper production, was studied. Two glasses, containing 30wt% W were melted for 30min at 1400 degrees C. The first batch, labeled WSZ, was obtained by mixing W, blast furnace slag (S) and zeolite tuff (Z), whereas the second, labeled WG, was prepared by mixing W, glass cullet (G), sand and limestone. The glass...

In reducing the high operating temperatures (≥800 °C) of solid-oxide fuel cells, use of protonic ceramics as an alternative electrolyte material is attractive due to their high conductivity and low activation energy in a low-temperature regime (≤600 °C). Among many protonic ceramics, yttrium-doped barium zirconate has attracted attention due to its excellent chemical stability, which is the mai...

Silicon carbide is the most important and versatile non-oxide ceramic. Powder injection molding (PIM) is a method of high-speed fabrication of complex near-net shapes of SiC and other powders. Green micro-machining (GMM) is used to extend the shaping capability of green ceramics and powder metallurgy to smaller feature sizes. Debinding—removal of organic additives—is the rate-limiting step in P...

In this paper, we suggest a novel recycling process for hard metal sludge that does not use ammonium paratungstate. Ammonia, which in the conventional is essential removing sodium and crystallized tungstate, was used process. Instead of ammonia, acid to remove tungstate resulting formation tungstic (H2WO4). Tungsten powders were successfully synthesized by hydrogen reduction through H2O decompo...

Cu–Al bronzes are interesting metallic materials, demonstrating higher hardness, wear resistance, corrosion resistance and a lower friction coefficient as compared with unalloyed copper. The powder metallurgy approach to the fabrication of these alloys presents opportunities tailor their phase composition grain size. In present work, structural characteristics, properties Cu-10 wt.% Al obtained...
