The powder compacts are sintered in air, hydrogen and inert (argon) atmospheres at a dilatometer and tubular furnace up to 1,350 °C. Sintering by activated surface concept (SAS) can anticipate and enhance the densification in such powders. Stepwise isothermal dilatometry (SID) sintering kinetics study is performed allowing determining kinetic parameters for Ni-YSZ and Ni-Cu-YSZ pellets. Two-steps sintering processes is indicated while Cu-bearing material features the smallest activation energy for sintering. The allied MA-SAS method is a promising route to prepare SOFC fuel cell anode materials.775-780openAccesspowderssinteringnickelcopperyttriumzirconiumpelletsmechanicsalloysfuel cellssolid oxide fuel cellsanodesArtigo de periódico29710.1007/s10973-009-0330-yhttps://orcid.org/0000-0002-0155-9100
