Abstract

Procedimiento para la fabricación de partículas sólidas que contienen peróxido cálcico, caracterizado porque se pulveriza sobre gránulos de peróxido cálcico en movimiento, una solución, una emulsión o una suspensión de un agente de envoltura que contiene un compuesto sólido insoluble en agua y que tiene un punto de fusión de al menos 50ºC o uno de sus precursores en un medio líquido y porque se evapora dicho medio líquido.
