Abstract
La industria cerámica española es una de las principales potencias a nivel mundial, posicionándose como líder en cuanto a desarrollo tecnológico, diseño y calidad de los productos. Tradicionalmente, el principal objetivo del sector era tanto reducir costes, como el impacto medioambiental. Sin embargo, debido a la gran competencia existente en dicho sector, surge la necesidad de conseguir una diferenciación en los productos. Esto se puede lograr gracias a la introducción de nuevas funcionalidades, frente a las tradicionales exigencias de resistencia y durabilidad.1,2El gran auge de la nanociencia en los últimos años ha permitido la creación de nuevos materiales con propiedades mejoradas. Tradicionalmente, las nanopartículas han sido introducidas en esmaltes cerámicos con fines decorativos. Sin embargo, apenas se ha seguido esta línea de investigación debido, fundamentalmente, a su elevado precio, la dificultad de manipulación, la toxicidad asociada a su pequeño tamaño y la tendencia a formar aglomerados debido a la alta reactividad, limitando su uso a nivel industrial. La formación in situ de materiales nanoestructurados podría ser una buena alternativa, ya que evitaría las dificultades anteriormente mencionadas, dotando simultáneamente al material cerámico de mejoras en sus propiedades, así como de funcionalidades exclusivas. Sin embargo, esta metodología de trabajo apenas ha sido implementada en el sector cerámico, a pesar de ser una alternativa innovadora y prometedora...
