Preparation and Characterization of LaAlO3 via Sol-gel Process

摘要：

　　Lanthanum aluminate powders were synthesized by sol-gel process with metal nitrates as raw materials,2-methoxyethanol/water as solvent and citric acid as chelating agent.The influence of this techniques (the amount of citric acid,pH value,calcination temperature and the ratio of 2-methoxyethanol/water) on the lanthanum aluminate powders were studied.The XRD shows pure LaAlO3 powders could be obtained after calcining at 600-900℃.The SEM analysis indicates that the LaAlO3 particles are uniform and nanosized with a range of about 40-70 nm,which is slightly larger than the estimated particle size using Scherrer formula.
