Coarsening mechanism of LiAlO2 in acidic and basic molten carbonate salts
Source abstract
Abstract
Abstract Long-term corrosion behaviors of molten carbonate fuel cell (MCFC) electrolyte matrix with LiAlO2 particle coarsening are evaluated in eutectic Li-Na carbonate melts with different pCO2. In low pCO2 (basic), the rapid growth of LiAlO2 particles by Ostwald ripening is observed. TEM analysis verifies the continued process of dissolution and precipitation of LiAlO2 nanocrystals that promotes LiAlO2 crystal growth. It is revealed that this growth process is accompanied by α–γ phase transition through a Li5AlO4 intermediate phase. In high pCO2 (acidic) conditions, oriented attachment, primarily between the (003) and (012) planes of α-LiAlO2 crystals, leads to interparticle coalition and growth.
