Optimizing Preparation Technological Parameters of Nano-LiAlO₂ Powder by Orthogonal Experiment

Abstract:

Citrate hydrolyzing method was used to prepare nano-LiAlO₂ powder, and the technological parameters were optimized by orthogonal experiment. The minimum size of LiAlO₂ powder was about 100nm, obtained when the green performs were sintered at 690°C for 2h, with the molar ratio of citric acid and metal-salt of 1:1 and concentration of Li⁺ of 0.5mol/L. XRD and SEM were used to examine the phase composition, particle size and microstructure. The LiAlO₂ powder had been agglomerated during the sintering process.
