Base electrogeneration was conducted on the steel cathode from 0.005M La(NO 3 ) 3 bath at the conditions of i=2mAcm −2 , T=60°C and t=25min for deposition of lanthanum hydroxide. The prepared hydroxide was then heat-treated at 600°C for 3h in dry air atmosphere. The physicochemical changes of the hydroxide deposit on heating were investigated by DSC-TG analysis. The structural characterizations by XRD, FT-IR and morphological observations via SEM showed that the well-crystallized and spindle-like nanostructures of La(OH) 3 and La 2 O 3 have been prepared. This work showed that nanospindles of La(OH) 3 and La 2 O 3 are easily achievable by cathodic deposition followed by heat-treatment.
