The energy sector is responsible for a significant amount of pollutant emissions associated with the entire production-to-consumption chain, so the need for efficiency measures to reduce production costs, energy use and consumption, and pollutant emissions is of primary interest. Obviously, this would not be possible without continuous developments and improvements in the materials field. The strong synergy between these two sectors, focused on innovation, is the key to this thesis. This thesis work develops a preliminary technical feasibility project for the joining of ceramic materials by means of polymer-derived ceramics (PDCs). In particular, ceramics are of great interest because of their exceptional properties of mechanical, thermal and chemical stability, corrosion resistance and environmental inertness, but high production costs and energy expenditure, combined with the complexity of obtaining large assemblies of complex shapes, limit the field and effective applications.
