The manufacturing and materials transformation industries generate residues, which do not always have an adequate ecological destination. In many cases, however, these secondary products can be directly re-used as raw materials in other industrial processes. In this context, this article presents the characterization of the sludge generated in the aluminum anodizing process and emphasizes the application potential of this residue as a raw material for the production of industrial ceramic filters. Results show that the high alumina contents (89-96 wt%) and composition constancy, as well as the low particle size (~1 m) after calcination and milling, render this residue a suitable raw material to produce alumina filters with optimized properties for casting engineering metal components with better performance.

Abstract

The manufacturing and materials transformation industries generate residues, which do not always have an adequate ecological destination. In many cases, however, these secondary products can be directly re-used as raw materials in other industrial processes. In this context, this article presents the characterization of the sludge generated in the aluminum anodizing process and emphasizes the application potential of this residue as a raw material for the production of industrial ceramic filters. Results show that the high alumina contents (89-96 wt%) and composition constancy, as well as the low particle size (~1 m) after calcination and milling, render this residue a suitable raw material to produce alumina filters with optimized properties for casting engineering metal components with better performance.
