Abstract

Procedimiento de curado en un sola etapa para la producción de artículos absorbentes de neutrones, preferentemente en forma de placas, caracterizado porque comprende curar irreversiblemente una mezcla, en forma del artículo deseado, de partículas de carburo de boro, resina fenólica curable en estado sólido y particulado y una proporción menor de un medio líquido que hierve a una temperatura inferior a 200ºC , a temperatura elevada, para aglomerar las partículas de carburo de boro por el polímero fenólico irreversiblemente curado.
