Structure of strontium barium niobate Sr x Ba 1 − x Nb 2 O 6 (SBN) in the composition range 0.32 ≤ x ≤ 0.82
The structure of strontium barium niobate crystals Sr x Ba 1 − x Nb 2 O 6 is comprehensively studied in the whole range of the tetragonal tungsten bronze phase ( x = 0.32–0.82) using both powder and single-crystal X-ray diffraction measurements. Unit-cell parameters, density, site-occupancy factors...

is comprehensively studied in the whole range of the tetragonal tungsten bronze phase (
x
= 0.32–0.82) using both powder and single-crystal X-ray diffraction measurements. Unit-cell parameters, density, site-occupancy factors and interionic distances show an explicit composition dependence which can be consistently explained using simple model calculations. The temperature dependence of the unit-cell parameters exhibits a remarkable anisotropy in a broad temperature region below the phase transition temperature. This proves that the electrostrictive contribution to the thermal expansion plays an important role in strontium barium niobate. |
