Abstract:	Nanocrystalline 0.1BiFeO 3-0.9SrBi 2Nb 2O 9 powder was successfully synthesized by a ethanolamine-modified sol-gel technique from compounds, Bi(NO 3) 3•5H 2O, Sr(NO 3) 2, Fe(NO 3) 3•9H 2O and Nb(OC 2H 5) 5 in solution ethylene glycol monomethyl ether. The powder exhibited amorphous in structure below annealing temperature 400 °C and a pure phase of layered perovskite ferroelectric structure at annealing temperature 600 °C. There was a considerable degree of particle coalescence when the xerogel was heated at 400 °C. The grains exhibited spherical shape distribution, and the average particle size of powder was in the range 50-100 nm after annealing at 700 °C. The ceramics exhibited a dense fracture surface consisting of lamellar grains. © 2004 Elsevier B.V. All rights reserved.
