Abstract

Molde de cerámica perfeccionado, caracterizado porque el diedro de solidificación se origina para moverse progresivamente a través del metal fundido, y comprende: a) una sección de comienzo (26) para contener una parte del metal fundido en el cual se inicia primeramente un diedro de solidificación; b) una sección de artículo (30) conformada para definir el artículo monocristal deseado; y c) una sección selectora (28) que conecta la sección de comienzo (26) con la sección de artículo (30) para originar el progreso del diedro de solidificación desde la sección de comienzo (26) hacia la sección de artículo (30) para tener la característica monocristal deseada, conteniendo la sección selectora un paso conformado como espiral (20) con mas de una vuelta, caracterizado porque la espiral (20) permanece a lo largo del eje (z) y por tener una entrada (L) que aporta una separación entre las vueltas contiguas del paso que es más de la mitad pero menor de dos veces el espesor del material de cáscara cerámico como se mide el espesor a lo largo del radio normal a dicho eje (z) en el diámetro más alejado de una vuelta del paso, uniendo el material de cascara cerámico en capas las vueltas contiguas del conducto en el diámetro exterior del conducto.
