Gamma lithium aluminate

γ-LiAlO2

is a potential candidate for MCFC matrix and tritium breeding material. Lithium aluminate pellets and pipes with thin walls were sintered with 2.45 GHz microwave applicator. It was shown that lithium aluminate ceramic was suitable to heating with microwave energy and to using lower sintering temperature and short heating time compared with conventional method. And above all special requirements on the material properties

such as ultimate compressive strength （C.S.）

narrow porosity distribution and homogeneous grain size were achieved. This provides a bright future for fast and high quality sintering of lithium aluminate.
