In the 21st century, a distinct technological progress has taken place with regard to ceramic tiles production. Both technological possibilities and the scope of application of the said material have improved. Full body ceramic tiles have started to appear in architecture not solely as a surface covering materials for concrete but also in applications that had not been earlier associated with ceramic tiles. This article focuses on approaching this subject in the context of the usage of large format porcelain stoneware tiles in the shaping of architecture. In this contemporary era, we are experiencing an exceptional evolution, on both technological and aesthetic aspects, when it comes to the production of ceramic materials, specifically porcelain stoneware tiles. Modern ceramic products, especially large format ceramic tiles, also referred to as siliceous sinter, offer nonconventional possibilities in design and an extended scope of applications of this material in architectural realizations.

In this study, we develop ceramic formulations based on quartzite and scheelite tailings collected from mining companies in the northeast of Brazil (Rio Grande do Norte State). New ceramic samples (27 wt% of kaolin, 29 wt% of plastic clay, 11 wt% of quartzite tailing, and 0–8 wt% scheelite tailing) were uniaxially pressed in two steps (20 MPa and 50 Mpa for 20 s); dried at 110 °C for 24 h; and sintered at 1150 °C, 1200 °C, and 1250 °C. The main mineralogical phases (mullite, quartz, calcite, and anorthite) of the sintered samples were identified using X-ray diffraction (XRD). After evaluation of the physical-mechanical properties (water absorption, linear shrinkage, apparent porosity, and flexural strength), it was observed that the incorporation of scheelite tailing by up to 8 wt% did not significantly alter the properties of samples sintered at all temperatures. Our results indicate that the new ceramics formulations developed have strong potentials in manufacturing sustainable materials such as ceramic tiles and porcelain stoneware.

In this work TiO2 and ZnO layers have been deposited by screen-printing in common glazed ceramic tiles. These layers were evaluated for the photocatalytic degradation of Orange II in aqueous solutions, in a batch photoreactor under visible light. The photocatalytic behaviour was assessed by taking into account experimental variables which include: (i) firing temperature of the TiO2 printed layer; (ii) layer thickness; (iii) operation time; (iv) pH; and (v) dye concentration. Optimal processed layers showed an interesting decolourisation performance (over 90% efficiency after 7-8 h). It is anticipated that these new ceramic materials might be developed as an interesting alternative to TiO2 or ZnO suspensions, for example in photocatalytic applications excusing the particles removal at the end of the process.

This project is devoted to the study of the felsite properties for the purpose of its application in the production of various types of fine ceramics: ceramic tiles, acid-resistant tiles, aluminosilicate proppants, etc. Felsite is a mixture of quartz (about 40%) and feldspars. In the compositions of ceramic masses, felsite can play the role of both nonplastic due to the quartz content, and flux due to the content of feldspars, that reduces the amount of mixture components. When felsite is fired, the melt appears at a temperature above 950°C. The felsite has a sintering effect when fired at a temperature of 1000°C. Glass phase enriched with SiO2 ensures the absence of material deformation after firing. Also, glassy phase provides high-acid and chemical resistance of materials based on it. In addition, after firing above 1150°C, felsite has a light color, which is a great advantage in comparing it as a melt with other iron-alkali-containing materials. Ceramics based on felsite does not require the use of opacified glazes.

To overcome the lack of micro manufacturing processes suitable for medium and large scale production as well as to process high resistive materials a special variant of micro injection molding is currently under development: micro powder injection molding (MicroPIM), which already enables the manufacturing of finest detailed components with structure sizes down to a few ten micrometer. In order to expand the scope of application of MicroPIM, tests are being conducted with pure tungsten powders or tungsten alloy powders. As further improvement, micro twocomponent injection molding allows, for example, the fabrication of micro components consisting of two ceramic materials with different physical properties.

Ceramic Composite Armor

Advanced ceramic materials are required to meet increasing high temperature demands of components in advanced propulsion engines for high performance aircraft as well as increasing structural demands in ceramic-composite armor. Monitoring the structural performance of these advanced ceramic materials presents challenges. Recently a new technology, Evisive ScanTM, based on microwave interferometry has been developed that allows condition monitoring. The internationally patented Evisive Scan™ method (1, 2, 3, 4, 5, 6), utilizes microwaves to interrogate dielectric materials. The microwaves are reflected at areas of changing dielectric constant. The reflected energy and the interrogating beam are combined to form an interference pattern which is measured in the transceiver as a signal voltage. The signal voltage is sampled at many positions in the inspection area. This point cloud is displayed as an Evisive Scan™ image, which presents volumetric detail of the inspected part. Over the past two years the technology has been demonstrated on Ceramic Matrix Composites and has shown to be an efficient measurement of porosity and manufacturing defects. The method has also been demonstrated to be applicable to ceramic composite armor made of monolithic ceramic tiles in complex, multilayer structures.

Ecological Landscape

Today’s landscape design targets at seeking for means of conveying the inner order of nature, and meanwhile satisfying people’s requirements of appreciation of beauty. However, plants are the main visual elements for expressing the two kinds of order. As the representative for natural environment, the ecological effect, the visual sense and the cultural landscapes of green plants penetrate and influence all the aspects of human lives and architectural environment. The interaction between environment and architecture has become a new exploration and direction of the architectural design thought in the 21st century.

In support of improved personal armour development, depth of penetration tests have been conducted on four different ceramic materials including alumina, modified alumina, silicon carbide and boron carbide. These experiments consisted of impacting ceramic tiles bonded to aluminum cylinders with 0.50 caliber armour piercing projectiles. The results are presented in terms of ballistic efficiency, and the validity of using ballistic efficiency as a measure of ceramic performance was examined. In addition, the correlation between ballistic performance and ceramic material properties, such as elastic modulus, hardness, spall strength and Hugoniot Elastic Limit, has been considered.
