Resumen de Desarrollo de pigmentos cerámicos con estructura espinela mediante el método de síntesis por combustión de una disolución
- español
En este proyecto de investigación se ha estudiado la aplicabilidad del método de síntesis por combustión de una disolución (SCD) para la generación de pigmentos cerámicos tipo espinela. Simultáneamente, se ha evaluado la influencia de diferentes variables del proceso (combustible, concentración de la disolución original, temperatura del horno y parámetros de un tratamiento térmico post-síntesis) sobre las propiedades finales del producto obtenido, tales como la estructura cristalina, microestructura y poder colorante.
De acuerdo con los resultados obtenidos, es posible concluir que el método SCD es una alternativa viable al método cerámico tradicional, que permite obtener pigmentos cerámicos muy esponjosos, con estructura de espinela y un elevado poder colorante, sin la necesidad de aplicar un tratamiento térmico posterior. Por otra parte, los pigmentos SCD presentan características altamente deseables en la decoración digital (inkjet) ya que no requieren procesos de molturación intensivos para acondicionar el tamaño de partícula al nivel submicrónico.
The present research project has evaluated the capability of solution combustion synthesis (SCS) for obtaining ceramic spinel-like pigments. Simultaneously, it has been analysed the influence of different combustion process variables (fuel, initial solution concentration, furnace temperature and post-synthesis thermal treatment parameters) over the final properties of the product obtained as crystalline structure, microstructure and colouring power.
According to obtained results, it can be concluded that SCS method is a feasible alternative to traditional ceramic method, which allows obtaining highly spongy ceramic pigments with spinel-type structure with an intense tinting strength, without needing any additional thermal treatment. On the other hand, SCS pigments present highly desirable features for digital decoration (inkjet technology), since they don’t require intense milling processes for conditioning particle size to submicrometric range.
