Abstract
Pigmento fosforescente, procedimiento para su obtención y sus aplicaciones. El pigmento fosforescente comprende una fase cristalina definida por la fórmula (I) en la que M es un metal divalente seleccionado entre Ca, Mg, Sr y Ba; R es un elemento seleccionado entre Dy, Gd, Nd, Er y Ce; x representa un valor comprendido entre 0,05 y 0,8; y representa un valor comprendido entre 0,001 y 0,3; y z representa un valor comprendido entre 0 y 0,3, opcionalmente junto con una fase vítrea y/o restos de compuestos mineralizadores añadidos a la mezcla de materias primas necesarias para la síntesis de dicha fase cristalina. El procedimiento comprende aplicar un tratamiento térmico a la mezcla de materias primas en presencia de un componente orgánico que se quema completamente durante dicho tratamiento térmico. De aplicación en el recubrimiento y decoración de superficies, por ejemplo, cerámicas. M(1-y-z)EuyRzAl2-xBx04.Phosphorescent pigment, procedure for obtaining it and its applications. The phosphorescent pigment comprises a crystalline phase defined by formula (I) in which M is a divalent metal selected from Ca, Mg, Sr and Ba; R is an element selected from Dy, Gd, Nd, Er and Ce; x represents a value between 0.05 and 0.8; and represents a value between 0.001 and 0.3; and z represents a value between 0 and 0.3, optionally together with a vitreous phase and / or remnants of mineralizing compounds added to the mixture of raw materials necessary for the synthesis of said crystalline phase. The process comprises applying a heat treatment to the mixture of raw materials in the presence of an organic component that burns completely during said heat treatment. Of application in the coating and decoration of surfaces, for example, ceramics. M (1-y-z) EuyRzAl2-xBx04.
