EDX elemental map of the pre‐oxidized MgO–steel cermet anode cross section after electrolysis. The development of inert anodes for aluminum electrolysis remains challenging due to the high corrosivity of cryolite‐based melts at 950°C–1000°C. This study investigates the corrosion and process behavior of a carbon‐free MgO–steel cermet anode derived from ...

Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process
This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...

Dust Cake Pressure Drop Determination of Surface Filters at Low Absolute Pressures
This study examines how the pressure drop of dust cakes on surface filters changes when the absolute pressure is reduced. In addition, it evaluates whether a model previously used to describe clean filter media can also capture the pressure drop behavior of dust cakes, thereby clarifying its applicability and limits under low absolute pressure ...
