【 摘 要 】

Perovskite structured stannates (Ba_{1â€�?�ð�?��?}Sr_ð‘�?SnO₃, ð‘�? = 0.0â€�??1.0) powders have been synthesized for the first time by molten salt synthesis (MSS) method using KOH as the flux at lower temperature (400°C) compared to other methods. The phase formation was confirmed by FTâ€�?�IR spectroscopy, powder X-ray diffraction (XRD) and the microstructure was analysed by scanning electron microscopy. XRD patterns reveal the formation of single phasic products for parent and substituted products with good crystallinity throughout the range (ð‘�? = 0.0â€�??1.0). The morphology of the particles of BaSnO₃ and SrSnO₃ is spherical and rod shaped, respectively. Effect of soaking periods on the grain growth is observed clearly in SrSnO₃. Ba_0.5Sr_0.5SnO₃ (BSS5) crystallizes in flake like morphology.
