Characterization of Aluminum Dross Compositions Using Rietveld XRD Technique, Standardless XRF Method and Carbon Analyzer

AluminumAluminum drossDross is a by-product generated during molten aluminumMolten aluminum treatment and castingCasting process. Knowing the composition of the drossDross will provide better environmental solutions through recyclingRecycling and reusing. In this research, Rietveld XRDXRD methodMethod is used to identify the crystalline phases present in drossDross. The XRDXRD analyses were used to develop template files to ease the phase identification process. The Alpha AluminaAlumina phase is carried out by Rietveld XRD and separate XRDXRD application since it is a crucial phase in aluminum smeltingAluminum smelting process. Omnian XRFXRF standardless application was able to obtain the trace elements available in drossDross. Unifying sample preparation for XRDXRD and XRF provided faster data reporting. In addition, Carbon content in drossDross is provided by a modified calibration of Leco Carbon analyzer. This methodology identified the crystalline phase of drossDross, the available trace elements, and the carbon content successfully with high accuracy and the fastest possible reporting time.
