Lanthanum chromate LaCrO3, an important catalyst and interconnect material used in solid oxide fuel cell was prepared from lanthanum nitrate hexahydrate La (NO3)3.6H2O (LN), chromium nitrate nonahydrate Cr (NO3)3.9H2O (CN) and glycine. The mixture was heated in Pyrex disc, resulting the formation of pure LaCrO3 at 180 0 C within five minutes. Other methods give LaCrO3 at 900 0 C. BET surface area of LaCrO3 prepared by combustion method was found to be 3.0 m 2 /g. Thermogravimetry, Differential thermal analysis, X-ray diffraction SEM techniques and atomic fluorence microscopy (AFM), were used to characterize the LaCrO3. Average particle size determine by Debay Scherrer’s equation was found to be ~16nm.
