Sodium nitrate (NaNO₃) is an inorganic ionic ceramic compound commonly encountered as a crystalline salt material. It is primarily used in industrial chemical processes, thermal energy storage systems, and as a constituent in molten salt mixtures for concentrated solar power applications, where its thermal stability and ability to store and release heat at elevated temperatures make it valuable. Engineers select NaNO₃-based systems for heat transfer and energy storage roles where cost-effectiveness and scalability are priorities, though it requires careful handling due to hygroscopic properties and corrosive behavior in molten form.
