Metal diborides are a class of ceramic materials with crystal structures consisting hexagonal sheets boron atoms alternating planes metal held together mixed character ionic/covalent bonds. Many the ultrahigh-temperature ceramics such as HfB2, TaB2, and ZrB2, which have melting points above 3000 °C, high mechanical hardness strength at temperatures, chemical resistance, while MgB2 is supercondu...

The use of burnable absorbers can be beneficial for nuclear reactors by extending the fuel's operational cycle, providing additional criticality control, and flattening power profile. In this work, three absorber materials (boron carbide, aluminum boride, zirconium boride) embedded in have been fabricated into foils clad AA-6061 potential high performance research reactors. as-fabricated boron-...
