The gamma-LiAlO/sub 2/ ceramic material is the reference candidate for the solid breeder option of the Next European Torus Program. The experiments and methodologies developed in Italy to produce high surface area gamma-LiAlO/sub 2/ powders to be compacted by cold pressing and sintering at 70 to 90% of the theoretical density, keeping a near fully open porosity is presented. The lithiating step was assessed for the Li/sub 2/CO/sub 3/ and Li/sub 2/O/sub 2/ precursors reacting with Al/sub 2/O/sub 3/ having submicron grain size. Sol-gel methodologies were also developed for the gamma-LiAlO/sub 2/ preparation by which very high surface area ceramic grade powders were obtained.
