Lithium-based oxide ceramics for tritium-breeding applications
Material preparation techniques, crystallographic data, phase diagrams, metal compatibility, and thermal properties have been assembled for the lithium-based oxide ceramics designated as potential solid tritium breeders for fusion devices. The materials discussed in this report include: Li/sub 2/O, ..beta..-Li/sub 5/AlO/sub 4/, ..gamma..-LiAlO/sub 2/, Li/sub 4/SiO/sub 4/, Li/sub 2/SiO/sub 3/, Li/sub 4/TiO/sub 4/, Li/sub 2/TiO/sub 3/, Li/sub 8/ZrO/sub 6/, Li/sub 4/ZrO/sub 4/, and Li/sub 2/ZrO/sub 3/. The thermal properties covered were vaporization, thermal conductivity, specific heat, and linear thermal expansion. There has been no attempt to rank the above mentioned candidates, but rather to merely indicate points that must be considered when using the various materials as solid breeders. These encompass low lithium atom densities, destructive phase transformations, a higher thermal expansion, low thermal conductivity, excessive vaporization at low temperatures, corrosive nature toward metals and difficulty in sample preparation.
