Nanostructured alumina from freeze-dried precursors
2011
Nanocrystalline alumina has been obtained on the 100 g scale by thermal decomposition of precursors resulting from the freeze-drying of aqueous solutions of different aluminum-containing products, namely aluminum acetate and aluminum l-lactate. Samples prepared at different temperatures (from 873 to 1573 K in steps of 100 K) were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and surface area measurements. In the acetate case, the transformation sequence involves the formation of θ-Al2O3 as an intermediate phase between γ-Al2O3 and α-Al2O3, whereas this θ phase is not observed in the lactate case. TEM and SEM i…
Nuevos grafitos e inscripciones ibéricos valencianos
1989
Con el propósito de poner al día los hallazgos epigráficos valencianos y, siguiendo el trabajo iniciado por Fletcher, completar el corpus de textos ibéricos, recogemos en este artículo una serie de grafitos procedentes de la revisión de los fondos de excavaciones antiguas (Tossal de Sant Miquel de Lliria, Los Villares de Caudete de las Fuentes, Despeñaperros de Paterna y Valentia), así como de hallazgos en recientes excavaciones en curso del Camp de Túria (Puntal dels Llops-Olocau y Castellet de Bernabé -Llíria).

The green factor in European manufacturing: a case study of the Spanish ceramic tile industry
2014
This paper analyses how environmental issues have affected and are continuing to affect the evolution of European manufacturing industries based on the example of the Spanish Ceramic Tile Industry (SCTI).1 The Ceramic Tile Industry (CTI)2 in Europe became very competitive and innovative in the early 1990s, with the Italian and the Spanish sectors, which are cluster-based, becoming world leaders. However, since 2008, this leadership position is being eroded. We provide an in depth analysis of the SCTI focusing on the influence of new European environmental regulations. The CTI has a major impact on the environment and has been the focus of environmental regulations. We also consider the inno…

La evolución energética del sector español de baldosas cerámicas
2014
espanolEl presente texto analiza como ha ido evolucionando el consumo y la eficiencia energetica de la industria espanola de baldosas ceramicas durante el siglo XX, y explora las posibilidades que se le plantean en el siglo XXI. Durante el pasado siglo este sector industrial acometio tres transiciones radicales al pasar de los combustibles tradicionales de biomasa a los hidrocarburos liquidos (fueloleo y gasoleo), y posteriormente a los gaseosos, principalmente gas natural. Aunque la informacion que permite evaluar de manera fiable la eficiencia energetica real en las plantas de fabricacion no es facil de obtener, los datos disponibles indican que se ha llegado a una elevada eficiencia con …
The technological evolution of the Castellón ceramic tile district: the contribution of the frit, glaze and colour industry
2008
[EN]: The industrial district of Castellón is characterized by a great dynamism based on technological innovation, both product and process, the origins of which are to be found on its providers, the machinery industry and the frit, glaze and colours industry. In this paper the current situation of the frit, glaze and colour industry is analyzed, accounting also for the situation of its main European competitor in Italy. The formation and development of the industry is also described in relation to the industrial district and the innovation system where it belongs, together with the R&D activity, the innovation activity, and the main technological milestones that have made it become the wor…
