| Resumo: | Cordierites exhibit high thermal stability and thermal shock resistance, which combined with their low price make them interesting in many industrial applications. However, they are limited by their relatively low mechanical properties compared to other technical ceramics and the simple geometries attainable by the current processing methods. Based on the literature on other ceramics, the reinforcement of cordierite with graphene will significantly improve their properties expanding their application range. Ceramic injection moulding (CIM) is an economic, jet unexplored, alternative for processing such composites in complex shapes. This work aims to set the basis of the use of CIM for the production of cordierite with reduced graphene oxide (rGO). Several rGO addition methods are scrutinized by determining the homogeneity of the resulting feedstocks and drawing conclusions on how it affects their rheological behaviour to combine adequate flow behaviour with the changes in mechanical and in target functional properties. |
