| Abstract Scope |
2D transition metal carbides, MXenes, are increasingly explored as potential additives in ceramic-based materialsdue to their high-temperature phase stability and high mechanical stiffness (483 GPa for titanium carbide MXene (Ti3C2Tx)). The layered morphology and colloidal stability of MXenes, characterized by a negative zeta potential (-35 to -50 mV), ensure their uniform dispersion in ceramics matrices, eliminating the need for additional surfactants to assemble MXene onto ceramic particles. In addition, high-temperature annealing studies have shown a phase transformation of Ti3C2Tx MXene to lamellar cubic TiCy. In this work, we explore the tailorable preparation of green bodies of nanometer-thick Ti3C2Tx MXene with silicon carbide (SiC) via electrostatic self-assembly followed by pressure-assisted pulsed current sintering at different temperatures (800 ºC – 1950 ºC). We investigated the phase transformation of Ti3C2Tx MXene within SiC matrix, which provides insights into phase stability and interaction of MXene with SiC as step toward additive manufacturing. |
