· JVASP-31179· Na2HF4

Sodium hydrogen fluoride (Na₂HF₄) is an inorganic ceramic compound belonging to the fluoride salt family, characterized by its ionic crystal structure. While primarily encountered in chemical processing and laboratory settings rather than structural applications, this material is used in specialized industrial contexts including uranium enrichment, metal surface treatment, and fluorine chemistry synthesis where its fluoride ion availability and thermal stability are exploited.
