· JVASP-12600· KHSeO3

KHSeO3 (potassium hydrogen selenate) is an inorganic ceramic compound belonging to the selenate family, characterized by its crystalline ionic structure. This material is primarily of scientific and research interest rather than a mainstream industrial ceramic, with potential applications in optical and electro-optical devices, ion-conducting ceramics, and specialized laboratory environments where selenate compounds are investigated for their unique crystal properties and phase transition behavior.
