Abstract
Industrial and ore exploration activities, when not aligned to clean technology procedures, use to generate huge quantities of wastes that might be very harmful to the environment. Their disposal is costly and frequently inappropriate, so their usage as raw materials for different applications is an important scientific and technological challenge. Considering the potential value aggregation in processes and products, industrial and mineral wastes recycling can also result in job and profit generation, fundamental aspects nowadays. Glass-ceramics produced from solid inorganic industrial wastes might be alternative products to porcelain stoneware tiles, materials with high aggregate value and increasing application in civil engineering. However, these wastes normally do not present adequate chemical composition for this kind of application, requiring the addition of commercial raw materials, and thus increasing the final product price. The employed technology uses mixtures of different Brazilian inorganic solid wastes, in order to achieve adequate glass batches for glass-ceramics production. Further sintering and crystallization studies of the glasses were performed. The used procedure (glass-ceramic sintering route) allows the generation of materials with low open porosity, the main problem of porcelain stoneware tiles.
