Magnesium diboride (MgB 2 ) has been explored as an alternative fuel to boron (B) due to its high energy density and the additive effect of magnesium (Mg) to promote B combustion. However, the primary oxidation of MgB 2 does not occur unless it decomposes at a high temperature (830 °C), which makes ignition difficult and the reaction slow. Recently, two-dimensional (2D) exfoliated MgB 2 nanosheets have attracted increasing attention due to their unique properties and potential applications in various fields. In this study, we investigate the potential of 2D exfoliated MgB 2 nanosheets as solid fuels for overcoming the challenges of MgB 2 combustion. We analyzed their oxidation behavior and energetic performance through material characterization and combustion tests under slow- and fast-heating conditions and compared their performance with those of bulk MgB 2 , B nanoparticles, and a B/Mg nanoparticle mixture. This study highlights the potential of MgB 2 nanosheets as promising solid fuels with superior energetic properties. |
