Prussian White is the promising cathode material for rechargeable sodium ion batteries. We study phase transitions in commercial Prussian White powder with particle size up to ∼ 10 *mm, which was chemically enriched with sodium, and synthesized sodium-enriched Prussian White with particle size of ∼ 1 *mm. X-ray diffraction was used to track structural changes during heating up to 250&suo(o)C. Both powders were found to undergo the transformation of initial rhombohedral phase to dehydrated rhombohedral phase through a formation of cubic phase. Smaller particle size of the synthesized powder leads to more effective dehydration, which decreases temperatures of all phase transitions by approximately 10&suo(o) C compared to commercial Na-enriched Prussian White.
