Abstract: Sinterable powders of lithium orthosilicate and lithium metazirconate were fabricated by a wet-chemical process. Sperical granules of lithium containing powders were prepared by a special powder metallurgical process and sintering in a fluidized-bed. The characteristics of the obtained pebbles meet the given specification for a breeder material of the Karlsruhe pebble-bed canister design for the blanket of a forthcoming fusion reactor.

Keywords: powder metallurgy; lithium orthosilicate; lithium metazirconate; wet-chemical process; sintering; pebble-bed canister design; fusion reactors; fluidized beds; sperical granules; lithium ceramics; breeder materials; nuclear fusion; ceramic powders.
