Abstract
Extra large Alkaline-earth Sr 2 + cation was successfully introduced into the B′-site of the complex perovskite A(B′ 1/3B″ 2/3)O 3 by a molten salt synthesis method. The crystal structure of the as-synthesized Ba(Sr 1/3Nb 2/3)O 3 was determined by Rietveld refinement of X-ray diffraction and Raman spectrum. The results showed that the as-synthesized Ba(Sr 1/3Nb 2/3)O 3 had the 1:2 order-disorder trigonal perovskite structure, which was also an isometric compound of hexagonal BaTiO 3-type structure Ba 3SrNb 2O 9. The measured dielectric properties on the perovskite Ba(Sr 1/3Nb 2/3)O 3 ceramics showed the good frequency stability and the low dielectric loss.
