Abstract:
The purpose of this article is to analyze the study of the thermal behavior of raw materials for ceramic tiles, through the use of pegmatite and shale residues, reducing the environmental impacts caused in the exploration of ornamental rocks. Therefore, this research started with the phase of preparation and composition of the samples, and then submitted them to the sintering test. After the physical tests, the results obtained pointed to the possibility of using residues for stoneware, semi-stoneware and porous, two formulations of different percentages (F1 and F2) being prepared. The specimens were sintered at 1050ºC, 1100ºC, 1150 ° C and 1200 ° C. According to ISO 13006, the formulations used at 1200ºC, showed characteristics for stoneware; F1 at 1150º showed characteristic of semi-stoneware, and F2 semiporoso; F1 and F2 both at 1100º | C had porous characteristics, and lastly F1 and F2 at 1050º had technical characteristics above porous.
