Abstract

1. Process for manufacturing dense anhydrous sodium carbonate, according to which light anhydrous sodium carbonate (2) is added to an aqueous sodium carbonate solution (6) and the resulting mixture (1) is treated within a temperature range above the transition temperature of sodium carbonate monohydrate to anhydrous sodium carbonate, characterized in that a saturated aqueous sodium carbonate solution (6) is employed, the addition of the light anhydrous sodium carbonate (2) to the said solution is performed within the abovementioned temperature range and the resulting aqueous suspension is subjected to a maturing treatment within this temperature range.
