An electrically conductive, oxidic target material includes a proportion of substoichiometric molybdenum oxide phases of at least 60% by volume, an MoOphase in a proportion of 2-20% by volume, and optionally an MoOphase in a proportion of 0-20% by volume. The substoichiometric molybdenum oxide phase proportion is formed by one or more substoichiometric MoO-y phase(s), where y is in each case in a range from 0.05 to 0.25. A process for producing the target material and a process for using the target material are also provided.

Target material for deposition of molybdenum oxide layers

A powder metallurgical molding forms an interconnector or an end plate for an electrochemical cell. The molding has a chromium content of at least 80% by weight, a basic shape of a plate and one or more flow fields with structuring formed on one or both of the main faces of the molding. A ratio of a maximum diameter Dof the molding, measured along the main face, to a minimum thickness dof a core region of the molding which extends along the flow field or fields and is not affected by the structuring lies in a range of 140&#x2264;D/d&#x2264;350.

Powder metallurgical molding and method of producing same

A powder metallurgical molded part includes a disk or plate-like main body and a row of knob-shaped and/or ridge-shaped elevations in a row direction having a height perpendicular to a main plane of the main body and a cross section with side flanks leading from an outer end contour in height direction of the elevation via rounded corner portions into curved portions with a curve radius. The curve radius merges into the surface contour of the main body and a rectilinear flank portion or tangent of the side flank lying at the point where the rounded corner portion merges into the curved portion is disposed at an angle of inclination to the main plane. At least two different angles of inclination are on the same side of the main body and the at least two different angles of inclination represent at least first and second geometries.
