Oxide based filter materials and filter structures with active and reactive functional pores (A02)

• Subject Area: Metallurgical, Thermal and Thermomechanical Treatment of Materials
• Term: from 2011 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 169148856

The aim of the project A02 is the investigation of active filter materials for the aluminum melt filtration for manufacturing thin- and thick-wall components based on aluminum. Due to the modification of the filter chemistry and roughness a high filtration efficiency over 95% of inclusions in the range of 1 to 100 is aimed. Thereby the following approaches will be investigated:a) Micro-structuring of reactive SiC filters with in-situ formation of mullite and silicon oxynitride as well as the investigation of the reactive contributions of carbon bonded alumina filtersb) Surface-structuring with the aid of electrophoresis, nano-structuring and freeze dryingc) Functional coatings based on kaliophilite
