STUDI HANTARAN LISTRIK SENYAWA SRN+1TINO3N+1 (N = 1 DAN 2) FASA RUDDLESDEN-POPPER YANG DISINTESIS DENGAN METODE LELEHAN GARAM
ABSTRACT: Srn+1TinO3n+1 (n =
1, 2,...n) Ruddlesden-Popper phase is a metal oxide compound with a layered structure
consisting of SrTiO3 perovskite layers and strontium oxide (SrO) layers, thus
this material has a potential as termoeletrik compounds that could be developed
as an alternativematerial for renewable energy. In this study, we examine one
of the 3 parameters of termoelectric properties, namely the electrical
conductivity. Srn+1TinO3n+1 (n = 1 and 2) Ruddlesden-Popper phases were synthesized
using molten salt method. The synthesis was carried out at 950 °C for 10 hours
with a ratio of precursor and salt were 1: 0.5. Structuralanalysis by X-Ray
Diffractometer (XRD) confirmed that all synthesized compounds formed Srn+1TinO3n+1
(n = 1, and 2) Ruddlesden-Popper phase with the characteristic peaks at 2θ =
31o, 32o, and 46o. The morphology analysis by Scanning Electron Microscope
(SEM) showed that the particles have plate-shaped with crystallites size were
20 nm. The electrical properties weremeasured using LCR meter with the highest
electrical conductivity of 2.25x10-7 S / cm which showed the semiconductors
behaviour.
