2. Caracterização de argilas de novos jazimentos situados em Parelhas/RN, Brasil, visando aplicação na indústria cerâmica
RESUMO O Estado do Rio Grande do Norte, mais especificamente no município de Parelhas, Brasil, a indústria cerâmica já é bastante consolidada, crescendo ano após ano. Entretanto, o estímulo do setor tem provocado acelerada exaustão das jazidas de argilas locais utilizadas pela indústria e, por conseguinte, ameaçando a manutenção da indústria cer

3. 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

4. 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

5. 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

6. Estudo da adição do resíduo proveniente da extração de minério de ferro em argilas do Rio Grande do Norte
The mining industry is responsible for the generation of waste from their natural process of extraction. The mining impacts in urban areas are of special importance due to the high urban occupation, which are exacerbated due to the proximity of the mined areas and populated areas. Some solutions to wastedisposal have the potential to significantly reduce the

7. Caracterização de matérias-primas regionais e desenvolvimento de formulações de massas cerâmicas para porcelanato
Initially concentrated in some poles at the South and Southeast regions of Brazil, the ceramic tiles industry became wide during the 80s decade, with a disconcentration industrial and regional pulverization. The competitiveness in the ceramic tiles internal and external consumers markets, it has debtor the industries to invest in sophisticated products each

8. Avaliação da potencialidade de argilas de queima clara como matérias-primas para o desenvolvimento de novos produtos cerâmicos
The industries of structural ceramics are among the most important production chains in the state of Rio Grande do Norte. The industry and other interest groups to target the replacement of firewood by natural gas. Studies accordingly concluded that simple change does not guarantee products of superior quality, and that the increase in spending on fuel can e

9. Influência do lodo de ETE na massa para fabricação de cerâmica vermelha
The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pol

10. Influência do teor de calcário no comportamento físico, mecânico e microestrutural de cerâmicas estruturais
There are ores of clay in Piauí State that are used for red structural ceramics, which are naturally contaminated with calcareous vein. This is one thing that impedes its exploration in an adequate way, especially for tile production. The present work aims at verifying the influence of the calcareous contents in the technological structural ceramics area, s

12. Caracteristicas da poeira do processo de fabricação de materiais ceramicos para revestimento : estudo no polo de Santa Gertrudes / Characteristics of dust from the manufacturing process of ceramic materials for tiles : study in the Santa Gertrudes complex
Dust generated in the process of manufacturing ceramic materials may be a hazardous agent to the health of workers, especially when silica polymorphs in crystal forms of ?-quartz and cristobalite are present in its composition. Occupational exposure to respirable dust of such polymorphs may lead to the onset of lung disease named silicosis and other associat
