摘要
Spheroidal indium tin oxide (ITO) nano-particles with In/Sn = 85:15 (at.%) were prepared by an emulsion technique under mechanical agitation without the aid of any surface-active agent. X-ray powder diffraction (XRD) indicated the stabilization of cubic ITO as the only phase at 250 degreesC. Particle size analysis showed a narrow distribution of 20-58 nm range particles with a mean size of 38 run, thus, confirming their nano-structured nature. The pellets sintered at 1350 degreesC for 6 h were found to have 95-97% of theoretical density. Thus, well sinterable nano-particles of ITO powders were prepared at a significantly low temperature compared to that in the reported methods. (C) 2002 Published by Elsevier Science B.V.
