Combustion Synthesis of Boride-Based Electrode Materials for Magnetohydrodynamic (MHD) Direct Power Extraction
The goal of the present project was to develop an advanced, low-cost manufacturing technique for fabrication of boride-based ultrahigh-temperature ceramics (UHTCs) that possess all the required properties to function as sustainable electrodes in magnetohydrodynamic (MHD) direct power extraction applications. Specifically, the project investigated use of mechanical activation-assisted self-propagating high-temperature synthesis (MASHS) followed by pressureless sintering for the fabrication of ceramic materials based on ZrB2 and HfB2 from inexpensive raw materials ZrO2, HfO2, and B2O3, with Mg as a reactant and NaCl or MgO as an inert diluent.
