中文摘要	Thin wall tubular Lithium aluminate ceramics have special application background. The microwave synthesis of LiAlO2 ultrafine powder, shape forming and microwave sintering of lithium aluminate pipes with 1mm in thickness were conducted in this paper. The results showed: (1) A controllable ratio of alpha to gamma phase LiAlO2 with average particle size of 0.3 mum can be synthesized via microwave radiation at temperature of 650-800degreesC within an hour; (2) Cold press and cold isostatic press are feasible methods to form LiAlO2 thin-wall tube and their mechanical properties are superior to those molded via hot pressure casting. (3) Lithium aluminate ceramic was successfully fabricated via microwave sintering, a uniform crystal size within 2-4mum, a typical bimodal pore size distribution and a average compressive strength more than 600MPa viere obtained at 1300degreesC for 30min.
