Novel insight into the structure and properties of lead-free dielectric Sr3TiNb4O15

Whittle, Thomas A; Brant, William R; Withers, Raymond; Liu, Yun; Howard, Christopher J.; Schmid, Siegbert

Description

Sr3TiNb4O15 has been synthesised and its structure and dielectric properties characterised. In contrast to previously reported results the compound has been found to form with Pna21 symmetry and unit cell dimensions a = 12.3631(19), b = 12.4027(19) and c = 7.7601(12) A. Variable temperature studies show a phase transition from orthorhombic to tetragonal symmetry at approximately 625 K, much higher than previously reported. Temperature-dependent dielectric measurements have also been performed...[Show more]

dc.description.abstractSr3TiNb4O15 has been synthesised and its structure and dielectric properties characterised. In contrast to previously reported results the compound has been found to form with Pna21 symmetry and unit cell dimensions a = 12.3631(19), b = 12.4027(19) and c = 7.7601(12) A. Variable temperature studies show a phase transition from orthorhombic to tetragonal symmetry at approximately 625 K, much higher than previously reported. Temperature-dependent dielectric measurements have also been performed and these correlate very well with the observed phase transition temperature.
