Trap and release of tritium formed in silica and alumina. [PDF]
Journal of Nuclear Science and Technology, 1981 The ability of trapping of tritium by silica and alumina which were preliminarily doped with Li and irradiated with neutrons, and the removal of tritium from these materials by ethylene were investigated. Tritium formed in almina was not liberated by the elevation of temperature to 350°C.
