Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-73315-6 This study achieves high-density potassium niobate ceramics via hot-pressing. It identifies a unique intragranular pore-evolution mechanism driven by lattice diffusion, revealing how these pores dictate the material’s chemical stability.
