Bubble Evolution on Different Carbon Anode Designs in Cryolite Melt
Stanic, Nikolina; Jevremovic, Ivana; Martinez, Ana Maria Cuellar; Sandnes, Espen (Peer reviewed; Journal article, 2020)The anode potential has been shown to be highly dependent on anode geometry and orientation in the Hall–Héroult process. This work is an experimental laboratory scale study of the effect of anode geometry and orientation ... -
Bubble Phenomena and Bubble Properties for Horizontal and Vertical Carbon Anode Surfaces in Cryolite Melt Applying a See‐Through Cell
Stanic, Nikolina; Martinez, Ana Maria Cuellar; Einarsrud, Kristian Etienne; Sandnes, Espen (Peer reviewed; Journal article, 2021)Gas bubble behavior on a carbon anode in a cryolite melt has been studied using a see-through cell. The phenomena studied have been growth, coalescence, detachment, and wetting during electrolysis. The surface orientation ... -
CO and CO2 Anode Gas Concentration at Lower Current Densities in Cryolite Melt
Stanic, Nikolina; Bø, Embla Knutsdotter Øi Tharaldse; Sandnes, Espen (Peer reviewed; Journal article, 2020)This work aims to study the CO-CO2 gas composition at low potentials and low current densities in cryolite melt with relatively low alumina content (≤2 wt%). There is a scarcity of data in the literature regarding the low ... -
The Effect of Varying Mixing Temperatures and Baking Level on the Quality of Pilot Scale Anodes - A Factorial Design Analysis
Sommerseth, Camilla; Thorne, Rebecca Jayne; Ratvik, Arne Petter; Sandnes, Espen; Linga, Hogne; Lossius, Lorentz Petter; Svensson, Ann Mari (Peer reviewed; Journal article, 2017)Identifying optimum anode baking level and mixing temperature are important when producing high quality anodes. The effect of varying mixing temperature and baking level were investigated in terms of the resulting apparent ... -
A Study of Bubble Behavior and Anode Effect on the Graphite and Industrial Carbon Anode in a See-Through Furnace During Aluminium Electrolysis
Stanic, Nikolina; Martinez, Ana Maria Cuellar; Einarsrud, Kristian Etienne; Sandnes, Espen (Peer reviewed; Journal article, 2022)Anode gas bubble behavior and anode effect on graphite and industrial carbon rod-shaped anode in a cryolite melt have been studied using a see-through furnace. The different carbon materials have different properties which ...
