Boron-Based Ceramics and Composites for Nuclear and Space Applications: Synthesis and Consolidation
Boron is one of the few elements to possess nuclear properties, which warrant its consideration as neutron absorber material due to its high neutron absorption cross section of 3838 barns (for thermal neutrons, 0.025 ev) for 10B isotope. Boron-based ceram

Abstract
Boron is one of the few elements to possess nuclear properties, which warrant its consideration as neutron absorber material due to its high neutron absorption cross section of 3838 barns (for thermal neutrons, 0.025 ev) for 10B isotope. Boron-based ceramics are used as a control/shutoff rod, neutron shielding for the nuclear reactor as well as spent fuel storage bays, neutron sensors for measuring the neutron flux in a nuclear reactor, and space applications. Refractory and rare earth metal borides possess superior thermophysical properties, which enables to T. S. R. C. Murthy (*) · K. Sairam · S. Majumdar · V.
