Abstract:
Li₄SiO₄ is a promising solid tritium breeding material due to its high lithium density, thermal stability, and excellent tritium release performance. The Li-n reaction inevitably produces helium atoms, which are initially produced in bulk. Helium atoms have a closed-shell structure and small...
