Environmental comparison of indoor floor coverings

Autores: Ros-Dosdá, T. et Al Appropriate selection of construction materials plays a major role in a building’s sustainable profile. The study sets out a comparative life cycle assessment of indoor flooring systems of different nature. The flooring systems consisted of coverings and, where required, bonding material and/or impact soundproofing material. The following coverings were assessed: inorganic (natural stone and ceramic tiles), polymer (carpeting and PVC), […]

Recycling of Malaysia’s EAF steel slag waste as novel fluxing agent in green ceramic tile production: Sintering mechanism and leaching assessment

Autores: Teo, P.T. et Al Electric arc furnace (EAF) slag is one of the most common by-products in the steelmaking industry. Despite various efforts of using this waste, there is yet a clear indication of EAF slag being recycled into commercial ceramic products, and most EAF slag ended up being disposed of through landfilling. Thus, a more thorough assessment is necessary to assure and convince the public […]

Effect of alumina source on the densification, phase evolution, and strengthening of sintered mullite-based ceramics from milled coal fly ash

Autores: Lu, J. et Al During the repair and restoration of buildings, ceramic tiles and blocks of Different alumina sources (Al(OH)3, Al2O3, and boehmite) were used to prepare mullite-based ceramics from milled coal fly ash. The effect of alumina source and sintering temperature on the densification and phase evolution of these ceramics was investigated. Among the three alumina sources, boehmite yielded the greatest densification and crystallization of the ceramics, and […]

Cutting stone building materials and ceramic tiles with diamond disc

Autores: Bezpalova, A. et Al During the repair and restoration of buildings, ceramic tiles and blocks of Al2O3 and ZrO2 are often cut. At present diamond abrasive discs are widely used for these purposes. The cutting process is accompanied by a considerable heat release and heating of the diamond disc. At a temperature of about 600°, the tensile strength of a disc is reduced by […]

Design for Children – Ergonomics in a Ceramic Tile’s Project

Autores: Salvador, C. A ceramic tile’s project, which is intended to stimulate the interaction of the child with his/her surroundings, was developed and prototyped. It focused on physical and emotional comfort through visual and tactile properties, targeting children but also parents as users and consumers. This project aims to create diversity by appropriation of the users, who may customize it using their imagination. The contribution […]

Absence of surface flaking in hierarchical glass-ceramic coating: High impact resistant ceramic tiles

Autores: E.Enríquez et Al. The impact resistance method is a useful procedure to determine the tile resistance. While other works are focused on modifying the tile support to improve the impact resistance, in this work, a new glass-ceramic material was developed to used it as glaze coating in order to relax impact tensions. This material possesses a hierarchical nano-microstructure consisted of microcrystal surrounded by nanostructured regions having […]

Ionoluminescence investigation of medieval Iranian luster glazed ceramics

Autores:  Nikbakht, T. et Al Ionoluminescence behavior of some golden glazed ceramic samples from the historical (12th-13th century) cite of Tappeh Ghale, located in the central part of Iran, has been investigated. The required complementary information of the samples, including their elemental compositions and depth profiles, have been provided by means of PIXE and RBS techniques. The results reveal the sensitivity of IL spectra to […]

Low-fusing porcelain glaze application does not damage the fatigue strength of Y-TZP

Autores:  Zucuni, C.P. et Al This study evaluated and compared the effects of two glaze application methods (brush and spray) on the fatigue strength and surface characteristics (topography and roughness) of a translucent yttrium stabilized partially tetragonal zirconia polycrystal ceramic (Y-TZP) prior to and after grinding. Disc-shaped specimens of translucent Y-TZP (Vita YZ-HT; Vita-Zahnfabrik) were processed (ISO 6872–2015) and randomly allocated into 6 groups, according to the surface treatments performed […]

Evaluation of carbon-based nanostructures suitable for the development of black pigments and glazes

Autores:  Kareiva, A. et Al Five different carbon-based samples were chosen for the fabrication of black pigments and glazes: historical ‘unknown’ wood charcoal, graphite, tailored graphitized soot, as-prepared multi-walled carbon nanotubes (MWCNTs) and purified MWCNTs. Ceramic glazes with carbon pigments were prepared with Pb3O4 and SiO2 in molar ratio of 2.85:1.9 and using 5 wt. % of pigment at 900 °C. The black pigments and […]

An impact of the molar ratio of Na2 O/K2 O on nanomechanical properties of glaze materials containing zirconium oxide

Autores:  Pasiut, K. et Al In this paper the nanomechanical properties of three groups of glass-ceramic materials were measured. The materials designated from the multicomponent system: SiO2-Al2O3-CaO-MgO-Na2O-K2O and the difference between them was the molar ratio of sodium oxide to potassium oxide, equal to, respectively 5.45; 1.19; and 0.77. Zirconium oxide was added to those materials, in three different amounts (1.5; 3; 6 wt%). The obtained […]
