Technological behavior of porcelain stoneware bodies with Egyptian syenites

Autores: Aydin, T. et Al The progressive depletion of the main feldspathic flux deposits in the World is forcing the ceramic industry to search for suitable substitutes. The aim of this study is to assess the potential of some feldspar sources in the Egyptian Eastern Desert, particularly syenites from Abu Khruq, in the manufacture of ceramic tiles. Beneficiated samples obtained by laboratory-scale mineral processing were […]

The effect of cement raw mix waste dust on porcelain tile properties

Autores: Aydin, T. et Al Nowadays, the recycling of industrial waste is one of the priority issues. Recycling studies related with reducing the negative effects of wastes on the environment are becoming increasingly important. It was believed that nothing was beyond recycling, and manufacturers should take greater responsibility for their part in the waste economy to apply cyclical solutions to an expanding breadth of new […]

A crystallization method for preparation of anatase-based glass-ceramic glaze

Autores: Zhao, H. et Al Developing a way to prepare effective, durable and high-temperature stable anatase-based photocatalytic ceramic is of great significance. In this work, we report a crystallization method for the preparation of anatase-based glass-ceramic glaze. The raw materials were made into frit and glazed on ceramic bodies. The glazed ceramics were sintered at 1180 °C and soaked at 700 °C. The effect of soaking temperature on the crystallization […]

Color removal from wastewater by photocatalytic process using titanium dioxide-coated glass, ceramic tile, and stainless steel sheets

Autores: Sirirerkratana, K. et Al Dye pollutants from textile industries are a major wastewater problem because they have complex chemical structures. Photocatalysis is a promising wastewater treatment method, which is used to remove dyes under light irradiation in the presence of a photocatalyst. In this article, titanium dioxide (TiO 2 ) photocatalyst was synthesized through sol-gel technique and coated on different substrates (i.e. transparent glass, glazed ceramic tile, […]

Laser-induced coloration of ceramic tiles covered with magnetron sputtered precursor layers

Autores: Rico, V.J. et Al This paper reports a new methodology for the coloring of glazed ceramic tiles consisting of the near infrared pulsed laser processing of copper containing oxide coatings prepared by magnetron sputtering. As a second approach, the employ for the same purpose of a novel laser furnace technique is also described. Changing the laser parameters and using the laser furnace to treat the tiles […]

ITC e ITENE velan por la seguridad del entorno ante los nanomateriales con ProSAFE

Castellón, 6 de marzo de 2019.- El Instituto de Tecnología Cerámica (ITC) y el Instituto Tecnológico del Embalaje, Transporte y Logística (ITENE) ambos miembros de la Red de Institutos Tecnológicos de la Comunitat Valenciana (REDIT) avanzan en el desarrollo del proyecto ProSAFE que tiene entre sus objetivos fundamentales evaluar la exposición a nanomateriales y partículas ultrafinas en ambientes industriales y urbanos. Alrededor de 3.000 empresas […]

Multilayered architectured ceramic panels with weak interfaces: energy absorption and multi-hit capabilities

Autores: Yazdani Sarvestani, H. et Al RESUMEN: Combining high strength and high toughness still remains a challenge in engineered materials. With the aim of improving the toughness of high-strength ceramics, multilayered architectured ceramic panels were developed inspired by natural materials such as nacre and conch shell. These panels were manufactured by stacking laser-engraved architectured ceramic tiles and commercial monomer Surlyn or Ethylene-vinyl acetate (EVA) resins. The mechanics of the […]

Evaporative cooling of porous tiles with seawater in a tropical climate with salty humid air

Autores: Pan, Z. et Al RESUMEN: Buildings on tropical islands in the South China Sea are facing an overheating challenge. High-water-absorbency unglazed porous ceramic (UPC) materials could counteract heat gain by evaporation. Salty humid air and seawater in the marine environment lead to evaporative cooling differences from inland conditions. This research replicated a salty humid atmosphere with a stable concentration similar to the actual environment in a […]

Assessment of the use potential of iron ore tailings in the manufacture of ceramic tiles: From tailings-dams to “brown porcelain”

Autores: Fontes, W.C. et Al RESUMEN: Nearly half of the total iron ore volume extracted in mining operations is rejected as tailings and disposed of in containment dams that are liable for considerable environmental impact and human hazard in case of breaching. This work aims to expand the usage possibilities of iron ore tailings and help mitigate the negative impact of tailings-dams without sacrificing the […]

Facile microwave-assisted synthesis of Cr2 O3 nanoparticles with high near-infrared reflection for roof-top cooling applications

Autores: Deepak, H.N. et Al RESUMEN: Microwave-assisted solution synthesis was employed for the preparation of Cr 2 O 3 nanoparticles using Cr(acac) 3 and ethylene glycol. The optimum conditions for the completion of the reaction forming a green precipitate (yield-95%) were: irradiation for 40–60 min at 220 °C solution temperature. The as-prepared sample was barely crystalline; annealing in air at above 300 °C formed nanocrystalline Cr 2 O 3 , as shown by X-ray diffraction […]
