Popis: espanolEn este proyecto de investigacion se ha estudiado la aplicabilidad del metodo de sintesis por combustion de una disolucion (SCD) para la generacion de pigmentos ceramicos tipo espinela. Simultaneamente, se ha evaluado la influencia de diferentes variables del proceso (combustible, concentracion de la disolucion original, temperatura del horno y parametros de un tratamiento termico post-sintesis) 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 metodo SCD es una alternativa viable al metodo ceramico tradicional, que permite obtener pigmentos ceramicos muy esponjosos, con estructura de espinela y un elevado poder colorante, sin la necesidad de aplicar un tratamiento termico posterior. Por otra parte, los pigmentos SCD presentan caracteristicas altamente deseables en la decoracion digital (inkjet) ya que no requieren procesos de molturacion intensivos para acondicionar el tamano de particula al nivel submicronico. 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.
