Abstract
1. Un procedimiento para la preparación de percarbonato sódico estabilizado que comprende las etapas de: poner en contacto partículas de percarbonato sódico con un agente de tratamiento que comprende una solución acuosa de una o más sales de metal alcalino-térreo soluble en agua en condiciones efectivas como para hacer reaccionar el percarbonato sódico en las superficies de dichas partículas con dicha sal de metal alcalino-térreo para formar una capa de superficie fina de carbonato de metal alcalino-térreo sobre las superficies de dichas partículas de percarbonato sódico; y posteriormente separar y secar dichas partículas tratadas superficialmente.
