Evaluation of the Reuse of Waste from the Polish Porcelain in the Development of Ceramic Products with Better Thermal Comfort

Abstract:

The ceramic industry, and others industries of manufacturing and transformation of materials produce, in greater or lesser degree, a quantity of waste that are not reused or doesn’t have a destination ecologically correct. Finding a correct destination for this kind of materials comes being a big tool for society nowadays. In this context, this work proposes the use of waste-based abrasive silicon carbide to promote growth in ceramic bodies to obtain ceramics for better thermal comfort. The porcelain polishing’s residue was added to ceramic mass at different percentages of mass. These samples were sintered the 1.200^oC. The results showed the increase in weight of the residue in the samples causes a decrease in the values of apparent and absolute density, and increasing the amount of pores in the material obtained. These pores are responsible for increased water absorption. Employing the program Quantikov was possible to determine the average pore size the sample; the samples identified as 1, 2 and 3 the increase in the content of waste to increase the average pore diameter opened. From the sample 3 to 7, the average pore diameter floats in an equilibrium value, an increasing the added amount of waste will increase porosity, but not its diameter. The sample 8 showed a low level of porosity. The results show the potential for reuse of the waste generated in the polishing of porcelain in the development of ceramics with better thermal comfort, reducing the impact caused by improper disposal and simultaneously reducing production costs.
