Abstract
The invention relates to a novel sodium percarbonate in the form of agglomerates of small crystals. The average particle size of the agglomerates is greater than 600 &mgr;m. The apparent density of the agglomerates is between 0.75 g/cm3 and 1.1 g/cm3, and the active oxygen is greater than 14%. The invention also relates to a process for the continuous manufacture of sodium percarbonate in a fluidized bed.
