Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA ESTABILIZAR PERCARBONATO DE METAL ALCALINO Y ESPECIALMENTE PERCARBONATO SODICO REVISTIENDOLO CON UNA SOLUCION ACUOSA DE UN ACIDO BORICO Y UNA CANTIDAD SOLUBILIZANTE DE UN METAL ALCALINO O SAL DE AMONIO, TAL COMO EN PARTICULAR SULFATO Y/O CLORURO POTASICO Y/O SODICO Y A CONTINUACION SE SECAN. LA PRESENCIA DE TAL SAL NEUTRA PERMITE UN MAYOR PESO DE AGENTE DE REVESTIMIENTO BASADO EN ACIDO BORICO PARA SU APLICACION AL PERCARBONATO EN UN VOLUMEN DADO DE SOLUCION ACUOSA, COMPARADA CON ACIDO BORICO SOLO.
