AFM, SEM and TEM Studies on Porous Anodic Alumina
Porous anodic alumina (PAA) has been intensively studied in past decade due to its applications for fabricating nanostructured materials. Since PAA’s pore diameter, thickness and shape vary too much, a systematical study on the methods of ...

Effect of the additive concentration on the modification of petroleum coke and anode quality
Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...

KINETICS OF THE ELECTROCHEMICAL OXIDATION OF ALUMINUM IN SULFURIC ELECTROLYTE [PDF]
It is investigated the kinetics of the growth of porous alumina by anodization in an aqueous solution of sulfuric acid. Kinetic data obtained as a result of the anodic process are extremely informative in terms of a general theory of pore formation in ...

Transient thermal modelling of green anode cooling in the aluminium industry
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.

POROUS ANODISATION OF ALUMINUM FILMS WITH PHOTOLITOGRAPHIC MASK UNDER HIGH FORMING VOLTAGES
The approach of aluminium porous anodisation has been proposed. Anodisation was realized under high forming voltages with Joule heat sink through aluminium tracks formed by a photolithographic mask.
