Effect of (5%) CO2 on the Oxidation Rate During Cooling of Industrial Aluminum White Dross
Solem, Cathrine Kyung Won; Deledda, Stefano; Zedel, Hannes; Tranell, Maria Gabriella; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2023)Aluminum (Al) white dross is classified as hazardous waste and originates from the primary production of Al as a result of molten metal oxidation at an industrial scale. As the produced dross reduces the annual metallic ... -
Evaluation of the Effect of CO2 Cover Gas on the Rate of Oxidation of an AlMgSi Alloy
Solem, Cathrine Kyung Won; Ekstrøm, Kai Erik; Tranell, Gabriella; Aune, Ragnhild Elizabeth (Journal article, 2020)Small additions of beryllium (Be) to aluminum magnesium (AlMg) alloys have proven to decrease their oxidation rate during industrial liquid metal handling. As Be can cause respiratory health issues, it is desirable to ... -
Experimental Study of the Thermal Stability and Chemical Reactivity of AlPO4-Bonded Ceramic Foam Filters (CFFs) in Contact with Molten Aluminium
Solem, Cathrine Kyung Won (Master thesis, 2018)Filtration of liquid aluminium is widely used in the industry for the removal of inclusions, and Ceramic Foam Filters (CFFs) are often the filtration media of choice. Following an incident with generation of PH3 (g) ... -
Heat Treatment of Mg-Containing Aluminum Alloys 5182 and 6016 in an Oxidizing Atmosphere with 4% CO2
Solem, Cathrine Kyung Won; Vullum, Per Erik; Tranell, Gabriella; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2022)Oxidation of liquid aluminum (Al) during processing is a widely known problem, and magnesium (Mg), as a common alloying element, increases the oxidation rate of the alloy. It has been established that small additions of ... -
Influence of Mg Concentration on the Inhibiting Effect of CO2 on the Rate of Oxidation of Aluminum Alloys 5182 and 6016
Solem, Cathrine Kyung Won; Solberg, Egil; Tranell, Gabriella; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2021)Oxidation of aluminum alloys during production is a well-known problem and contributes to significant metal losses. As small additions of CO2 in the oxidizing atmosphere has proven to inhibit the oxidation rate for ... -
Parametric Study of Molten Aluminium Oxidation in Relation to Dross Formation at Laboratory and Industrial Scale
Solem, Cathrine Kyung Won (Doctoral theses at NTNU, 2022:341, Doctoral thesis, 2022)Aluminium (Al) white dross, classified as a hazardous waste, is a heterogeneous mixture of metallic Al, oxides, and non-metallic compounds (NMC) originating from the primary production route of Al. Over the past few decades, ... -
Preliminary Experimental Study of the Thermal Stability and Chemical Reactivity of the Phosphate-Based Binder used in Al2O3-Based Ceramic Foam Filters (CFFs)
Solem, Cathrine Kyung Won; Fritzsch, Robert; Aune, Ragnhild Elizabeth (Journal article; Peer reviewed, 2018)Filtration of liquid aluminium is widely used in the industry for the removal of inclusions, and Ceramic Foam Filters (CFFs) are often the filtration media of choice. It is known that PH3 (phosphine) can be released from ... -
Sampling Procedure, Characterization, and Quantitative Analyses of Industrial Aluminum White Dross
Solem, Cathrine Kyung Won; Deledda, Stefano; Tranell, Gabriella; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2022)Up to 10% of all metallic aluminum (Al) produced is lost due to dross generation during production. It also causes an environmental problem due to hazardous waste generation following treatment, as well as toxic gas ...
