· JVASP-26114· Na3PSO3

Sodium phosphite (Na₃PSO₃) is an inorganic ceramic compound belonging to the phosphite salt family, characterized by a phosphorus-oxygen framework with sodium cations. This material is primarily investigated in research contexts for applications in solid-state ion conductors, phosphate-based ceramics, and specialized chemical synthesis; it is not a mainstream commercial engineering ceramic but represents a class of phosphite compounds with potential relevance to electrochemical and thermal barrier applications where phosphorus-containing ceramics offer advantages in specific chemical environments.
