Preparation and Characterization of Bi-doped LaAlO3 via Sol-gel Process

摘要

A series ofBi-doped BixLa1-xAlO3 (x=0.0,0.1,0.2,0.3,0.4) powders have been prepared by sol-gel method at 800℃.The influences of Bi doping content on phase,morphology,particle size,surface area,infrared absorption spectrum are discussed.XRD results show that there is no second phase in powders when x≤0.3,however,there exist impure phases when x≥0.4.The SEM analysis indicates the particle size of powder is 50-150nm.The specific surface area is 5-13 m2/g.
