Abstract

The dielectric and pyroelectric properties of trivalent-samarium doped barium strontium sodium niobate tungsten bronze structured ceramics are further modified with monovalent-Lithium. Ba 1.6-(3/2)y Sr 2.4Sm yLi xNa (2-x) Nb 10O 30 was studied for y = 0.1 and ? in the range of 0 = ? = 1. The BSSLNN ceramics can be indexed by typical orthorhombic structure and these orthorhombic (mm2) peaks are assigned to standard file No. C73-1214. Tolerance factor and average electronegativity difference has been determined for BSSLNN ceramics. Pyroelectric and DC resistivity properties of BSSLNN ceramics are reported. ? = 1 composition was found to be optimum among the series for possible pyroelectric applications. © Springer Science+Business Media, LLC 2008.
