Tricalcium aluminate hexahydrate (TCA) is a compound used in the Bayer process during green liquor polishing, acting as a filter aid. This study analyzes the formation mechanism of TCA using different liquors, comparing the resulting products to determine the most suitable for filtration. Techniques such as electron microscopy (SEM) and X-ray diffraction (XRD) were employed to evaluate the microstructure of the formed calcium compounds
