14. Evaluation of kaolin and bauxite from the Amazonian region addition on mechanical-, physical-, chemical properties and microstructural characterization of red ceramic industry clay of Manaus metropolitan region
ABSTRACT The present work investigated properties of red ceramic from the Amazonian region after the addition of kaolin and bauxite mixture with 0, 10, 20 and 30%wt. in red ceramic industry clay. Assessed mechanical properties were flexural strength and Young's modulus. The assessed physical properties were density and porosity. The microstructural images we

15. Characterization and Evaluation of Ceramic Properties with Spherical and Prismatic Samples of Clay Used in Red Ceramics
The Brazilian red ceramic industry monthly consumes about 10.3 million tons of clay, its main raw material. In most potteries, characterization of the clay is made empirically, which can result in roof tiles and blocks not according to standards. In this sense, this paper aims to characterize clays used in the manufacturing of red ceramic products in a facto

16. Incorporation of in Natura and Calcined Red Muds into Clay Ceramic
Brazil is one of the world greatest aluminum producer and also comprises a large industrial sector dedicated to the production of alumina (Al2O3) by the traditional Bayer process. During this process an insoluble residue, known as red-mud, is generated and normally discarded. A possible use for the red mud is its incorporation into clay ceramics. Indeed, thi

17. Evaluation of the Incorporation of Waste Generated from Titanium Dioxide Manufacturing in Red Ceramics
Rotary-vacuum-filter mud (RVFM) is waste generated during the manufacturing process of titanium dioxide. In this work, RVFM and ceramic bricks containing different ratios of this waste are investigated. The mud samples were characterized using thermal analysis (TG/DTG). The aim of the present work was to determine the effect of adding RVFM on the ceramic pro

18. Thin films produced on 5052 aluminum alloy by plasma electrolytic oxydation with Red Mud-containing Electrolytes
In this paper, we propose the production of ceramic protective thin films by plasma electrolytic oxidation using red mud-containing electrolytes. The treatments were performed through the application of pulsed voltage (600 V, 200 Hz) during 300 seconds to aluminum samples immersed in electrolytic solutions with 5 g of red mud per liter of distilled water. Th

19. Starch consolidation of red clay-based ceramic slurry inside a pressure-cooking system
The consolidation of red clay-based slurry by gelatinization of starch in a domestic pressure cooker was presented. Aqueous ceramic slurries were prepared consisting of a ternary powder mixture of red clay, quartz, feldspar, and different starch types. The starch slurries with and without the presence of ceramic particles demonstrated the same gelling mechan

20. Application of bauxite waste from amazon region in the heavy clay industry
In this work, a method was developed for the application of red mud, an alkaline leaching waste, from a bauxite processing plant located in northern Brazil (Amazon region) as starting material for heavy clay products. Samples were prepared by pressing blends of red mud and clay, which were then fired at temperatures from 900 ºC to 1190 ºC. Characterization

21. Aqueous dispersion of red clay-based ceramic powder with the addition of starch
The optimum dispersion and rheological properties of red clay-based ceramic suspension loaded with unary and binary starch were investigated in aqueous medium. The aqueous ceramic suspension was prepared consisting of red clay, quartz, feldspar, and distilled water. Using a polyelectrolyte dispersant (Darvan 821A), the ternary ceramic powder was initially op

23. Energetic use of wood waste in one center for the production of red ceramics in São Paulo State / Uso energético de resíduos madeireiros em um pólo de produção de cerâmicas vermelhas do Estado de São Paulo
The use of forest biomass is an important alternative of renewable energy source, economic, technical and environmentally viable, fighting for space with other energy sources, more expensive or non-renewable, such as natural gas, electricity, diesel and LPG. Within the industrial sector, biggest consumer of biomass energy, the segment of red ceramics represe

24. Social and Environmental Impacts Caused by Ceramic Industry Activities of the Municipality of Red Crato-Ce / Impactos socioambientais causados pelas atividades da indÃstria de cerÃmica vermelha do municÃpio de Crato-Ce
The ceramic activity has an important role in the Brazilian economy. However there are big impacts on the environment and society, causing changes in the environment and in the lives of people who perform these activities or live close to sites of raw-material exploitation or manufacturing of ceramic products. In this perspective, this study aimed to analyze
