Caracterização de peças cerâmicas obtidas a partir do resíduo do granito asa branca com adição dos produtos da combustão do carvão mineral

Abstract

During the burning of coal in power plants, are generated several types of waste, called combustion coal products (CCP's).Currently, these materials have been investigated by presenting several technological applications, such as in the manufacture of ceramics. This experiment studied the feasibility of adding CCP as reinforcement phase in ceramic parts fabricated from the residue of granite.Two batches of parts were made: one without the addition of PCC's, and the second with the addition of 10 % wt CCP. Analysis were performed fluorescence X-rays to identify and quantify the elements contained in the sample Vickers Microhardness tests to assess the influence of the CCP on the mechanical performance parts. The X-ray fluorescence showed that the CCP in terms of chemical composition, has great potential for incorporation as reinforcement in a ceramic matrix phase. The products of combustion of the coal increased the hardness of the ceramic test samples. These results indicate that the CCP used have potential to be incorporated into ceramic pieces made from waste granite.
