A novel approach to the synthesis of Ti3SiC2 MAX phase ceramic materials using macrosized non-powder forms of titanium metal, such as foils, sheets, rods, tubes, etc., as a reactant was developed. According to this method, dispersions of SiC particles in slurries or pastes as well as tape casted polymer films filled with SiC particles can be used as a second component of the reaction system. Heat treatment under oxygen-free conditions at 1350-1500°C enables the SHS and RMI processes to occur in the reactive assemblies, allowing them to be sintered into a dense ceramic composites with a damage tolerant Ti3SiC2-based matrix reinforced with hard SiC particles. It was demonstrated that the proposed approach can be applied for fabricating Ti3SiC2/SiC ceramic matrix composites with specified internal structures including cellular and cannular ones. Since there is no need for a high pressure assistance during the sintering process, the method is expected to provide the Ti3SiC2 MAX phase ceramic materials with important competitive advantages through an increase in manufacturing productivity.
