Estudo da sintetização de produtos cerâmicos fabricados a partir da cinza da combustão da lenha.

Abstract

With a concern to preserving the environment, the proper disposal of industrial waste has become the basis for studies to formulate techniques based on sustainable development. The use of firewood as fuel for ceramic ovens and potteries leads to the production of ash in large quantities. One possibility for the use of these ashes is their application as a raw material for ceramic products with or without the addition of other materials, since their chemical composition is similar to this type of material, in order to reduce the environmental impacts caused by improper disposal of this waste. In view of this, this study aimed to evaluate the viability of the production of ceramic products, by powder metallurgy, from the product of firewood combustion. For the analysis of the physical and mechanical properties of the samples, the following tools were used: X-ray fluorescence, Rockwell hardness, mass variation, linear shrinkage and porosity. The results obtained proved the feasibility of using ash as a rawmaterial for ceramic pieces.
