Title (EN) MANUFACTURE OF CERAMIC TILES FROM FLY ASH
(FR) FABRICATION DE TUILES EN CERAMIQUE A PARTIR DE CENDRES VOLANTES
Abstract: front page image
(EN)The present invention relates to a process for forming glass-ceramic tiles. Fly ash containing organic material, metal contaminants, and glass forming materials is oxidized under conditions effective to combust the organic material and partially oxidize the metallic contaminants and the glass forming materials. The oxidized glass forming materials are vitrified to form a glass melt. This glass melt is then formed into tiles containing metallic contaminants.
(FR)Procédé de fabrication de tuiles en vitrocéramique. On oxyde des cendres volantes contenant de la matière organique, des contaminants métalliques et des matières formant du verre dans des conditions efficaces pour brûler la matière organique et oxyder partiellement les contaminants métalliques et les matières formant du verre. On vitrifie les matières formant du verre qui sont oxydées pour former une fonte de verre. On forme ensuite des tuiles avec cette fonte de verre, lesdites tuiles contenant des contaminants métalliques.
