Zusammenfassung:PURPOSE:To manufacture fine crystals of the adduct of hydrogen peroxide to sodium carbonate by adding Na2CO3 and H2O2 to mother liquor contg. Na2CO3, H2O2 and a silicic acid compound as a stabilizer for H2O2 by a restricted amount basing on the amount of Mg and by reacting the compounds. CONSTITUTION:Na2CO3 and H2O2 are simultaneously added to mother liquor contg. 7-20wt% Na2CO3, 1.5-6wt% H2O2 in 1.3-0.2 molar ratio between Na2CO3 and H2O2, an Mg compound such as MgSO4 as a stabilizer for H2O2 by 0.001-0.5wt% expressed in terms of Mg, and a water soluble silicic acid compound such as sodium silicate as a stabilizer for H2O2 by 0.003-0.1% expressed in terms of Si in
