Sodium phosphate (Na₂HPO₄) is an inorganic ceramic compound belonging to the phosphate salt family, commonly used as a white crystalline powder in industrial and laboratory applications. It serves primarily as a buffering agent, dispersant, and raw material in detergents, food processing, water treatment, and ceramic manufacturing, where its mild alkalinity and solubility make it valuable for pH control and as a precursor for advanced phosphate ceramics. Engineers select this material for applications requiring chemical stability, non-toxicity, and compatibility with aqueous systems, though its hygroscopic nature and moderate thermal stability limit use in high-temperature structural applications compared to phosphate ceramics engineered for biomedical or refractory purposes.
