简介
6Li produces tritium by (n, α) nuclear reaction, 6Li+1n→4He+3H. Lithium titanate (Li2TiO3) enriched with 6Li, is the most promising candidate for solid test blanket module (TBM) material for fusion reactors. Various processes are reported in literature for the fabrication of Li2TiO3 pebbles for its use as TBM material. A process has been developed based on the solid state reaction of lithium-carbonate and titanium-dioxide for the synthesis of lithium titanate and pebble fabrication by extrusion, spherodization and sintering. This paper discusses the sequence of steps followed in this process and the properties obtained. Analytical grade titanium-dioxide and lithium-carbonate were taken in stoichiometric ratio and were milled to ensure thorough intimate mixing and obtain fine particles less than 45μm before its calcination at 900°C. Following calcination, the agglomerated product was again milled to fine particles of size …
