The goal of CEM-WAVE is the introduction of an innovative Ceramic Matrix Composites (CMCs) production process, based on Microwave-assisted Chemical Vapour Infiltration (MW-CVI) technologies. This novel proposed process will extremely reduce processing costs, thus making CMCs sustainable for process industries in energy-intensive sectors such as steelmaking. In more detail, CEM-WAVE aims at validating, in a radiant tube furnace, a small scale CMC-based tube, substituting the Inconel/Stainless steel alloys currently employed.
