“…Decreasing viscosity does not only result in less closed porosity but also favours spherical pore morphology, which is critical for getting porcelain stoneware tiles with high stain resistance (76). Although lower the viscosity results in less and spherical closed porosity with improved stain resistance, too low viscosity can bring additional problems such as pyroplastic deformation of the tiles, which is a factor to consider in the formulation of the ceramic body.…”

Porcelain stoneware is a strongly sintered ceramic material fabricated from ball clays-quartzfeldspar mixtures. Porcelain stoneware is characterized by its excellent technical and functional properties (low water absorption, high mechanical properties, resistant to chemical substances and cleaning agents, aesthetic possibilities …). These characteristic and technical features make that among the different types of ceramic tile, porcelain stoneware is the ceramic product that in the last years has best withstood the economic crisis in the construction sector. These properties are related to the microstructure of porcelain stoneware, which is a grain and bond type with large particles of filler (quartz), mullite crystals, a silica-rich amorphous phase and porosity. The understanding of the relationship between the microstructure and the properties of porcelain stoneware is hardly important for the development and design of these materials whose tendency is the manufacture of thinner tiles with higher dimensions but must continue to comply the specific technical requirements. RESUMEN:Relación entre la microestructura y las propiedades tecnológicas en gres porcelánico. Revisión bibliográfica. El gres porcelánico es un material sinterizado fabricado a partir de una mezcla de arcillas, cuarzo y feldespato. Tecnológicamente, el gres porcelánico se caracteriza por sus excelentes características técnicas y funcionales (baja absorción de agua, buenas propiedades mecánicas, resistente a substancias químicas, posibilidades estéticas…). Estas cualidades han propiciado que, entre los diferentes tipos de baldosa cerámica, es el gres porcelánico el producto que mejor ha resistido la crisis económica sufrida por el Sector de la Construcción. Las propiedades tecnológicas están relacionadas con su microestructura, compuesta de partículas de cuarzo, cristales de mullita, fase amorfa y porosidad. El conocimiento de la relación entre la microestructura y las propiedades tecnológicas del gres porcelánico es de gran importancia para avanzar en el diseño y desarrollo de estos materiales, cuya tendencia es la fabricación de piezas de mayor formato y menor espesor pero que deben seguir cumpliendo con los requerimientos especificados para su aplicación.

“…Because porcelain consists generally of a 70% glassy phase and a 30% crystalline phase, the viscosity of the glassy phase and the amount of the crystalline phase control the pyroplastic deformation resistance of these materials [12]. Calcite and dolomite can be used to accelerate the melting of feldspars and to reduce the firing temperature without significantly changing the pyroplastic deformation behavior.…”

“…The water absorption rate firstly decreases and then increases with the increase of temperature. When the firing temperature is 1190°C, the linear shrinkage and bulk density of the sample reach a maximum value of 7.55% and 2.42 g/cm 3 , respectively, and the water absorption rate reaches a minimum value of 0.03%, which are close to the properties (e. g. bending strength of 45 MPa, water adsorption of 0.06% and linear shrinkage of 7.58%) of the commercial porcelain building tiles.…”

In this paper, to save energy and reduce consumption in building ceramic process, the low temperature porcelain building tiles were prepared by fast firing process using two kinds of "K 2 ONa 2 O" feldspar with different amounts of alkaline and alkaline earth oxides fluxing agents, Si/Al ratio and melting point. The sintering properties of the samples were evaluated by linear shrinkage, water absorption and bulk density. The crystalline phase and microstructure of the samples were characterized by X-ray diffraction and scanning electron microscope. The results showed that the optimum linear shrinkage of 7.55%, water absorption of 0.03% and bending strength of 78.385.8 MPa can be achieved for the sample fired at 11701190°C, which is attributed to the effect of the combined "K 2 ONa 2 O" feldspar flux system.
