FORMULATION AND CHARACTERIZATION OF CERAMIC PARTS FOR COATINGS MADE FROM THE PRODUCTS OF COMBUSTION OF MINERAL COAL

The use of coal as fuel in various industrial processes such as thermoelectric and steel mills generates relevant amounts of waste or by-products, called coal combustion product (CCP’s). Therefore, viable alternatives for the correct disposal or technological applications of this by-product are studied with or without the addition of reinforcement phases in order to reduce the environmental impacts caused. Among these applications, one possible approach is the use of CCP’s for the manufacture of ceramic tiles, since these residues are chemically similar to several ceramics. Therefore, this work aimed to evaluate some physical and mechanical properties of CCP’s to observe the feasibility of manufacturing ceramic parts for coating from the product of coal combustion. The results confirmed the potential and feasibility of using CCP’s to completely compose the ceramic tiles matrix.
