Carbon anodes for aluminium production are produced from calcined petroleum coke (CPC), recycled anode butts and coal tar pitch (CTP). The CO₂ produced during anode consumption contributes to a substantial amount of the CO₂ footprint of this industrial process. Charcoal from wood has been suggested ...

During production of aluminum in Hall-Héroult cells, carbon anodes electrochemically oxidize to form mainly CO₂. The CO₂ bubbles block the anode working surface during growth and coalescence, leading to cell voltage loss and voltage oscillations. Lower grade isotropic petroleum cokes are curren...

Micro X-Ray computational tomography (µ-CT), has been applied to study the bubble distribution across the wall of fused quartz crucibles used for Czochralski pulling of monocrystalline silicon ingots for solar cells. Two crucibles from different suppliers has been used in the study. One set of ...
