Sodium tetrafluoroborate (NaBF₄) is an ionic ceramic compound used primarily as an electrolyte and flux material in high-temperature electrochemical and metallurgical processes. It is valued in industrial applications requiring thermal stability and ionic conductivity, particularly in molten salt environments where conventional materials degrade. Engineers select NaBF₄ over alternative fluoride salts when the combination of thermal stability, low hygroscopicity, and chemical inertness is critical to process efficiency or product quality.
