Paper Title:
Preparation and Characterization of Lead-Free Na0.54K0.42Li0.04NbO3 Nano-Powders by Sol-Gel Method
  Abstract

In this paper, Na0.54K0.42Li0.4NbO3 nano-powders were prepared by the sol-gel method, Na2CO3, K2CO3, Li2CO3 and Nb2O5 as raw materials, citric acid as coordination agent, ethylene glycol as esterifying agent, polyethylene glycol as dispersing agent. From the XRD, TG-DTA and TEM analysis, powders’ size, lattice constants and surface topography were studied. The results showed that under the condition of 600°C × 2h, nano-powders showed good dispersiveness and no reuniting, with pure orthorhombic perovskite structure and various grain sizes was 40.78 nm.
