Kaolin was used as a silica and alumina precursor in the hydrothermal synthesis of kalsilite with the addition of potassium carbonate (K₂CO₃) as a potassium source. The effects of different K₂CO₃ concentrations have been studied. After a 24-hour hydrothermal reaction at 200°C, kaolin treated with 1....
