Abstract The nanocrystalline Bi 2 O 3 -Y 2 O 3 solid electrolyte material was synthesized by pressureless reactive sintering process with Bi 2 O 3 and Y 2 O 3 nano mixed powder as raw materials, which was prepared by a chemical coprecipitation process. The study on the behavior of nano δ-Bi 2 O 3 formation and its grain growth showed that the solid solution reaction of Y 2 O 3 and β-Bi 2 O 3 to form δ-Bi 2 O 3 occurs mainly in the initial stage of sintering process, and nano δ-Bi 2 O 3 crystal grains grow approximately following the rule of paracurve (( D − D 0 ) 2 = K·t ) during sintering process. After sintered at 600°C for 2 h, the samples could reach above 96% in relative density and have dense microstructure with few remaining pores, the δ-Bi 2 O 3 grains are less than 100 nm in size.

Fluorite Ce0.8Sm0.2O2-δ (SDC) nanopowder with a crystallite size of 15 nm was synthesized by a co-precipitation method. An SDC porous layer was coated onto a BaCo0.7Fe0.2Nb0.1O3-δ (BCFN) mixed conductor to improve its oxygen transport behavior. The results show that the SDC-coated BCFN membrane exhibits a remarkably higher oxygen permeation flux (
