Description

Phosphoric Acid, Ammonium Sodium Salt is a versatile inorganic salt with a unique combination of ammonium and sodium cations. This compound is valued for its role as a buffering agent and a source of phosphorus and nitrogen in specialized industrial formulations. It is primarily utilized in sectors such as water treatment, specialty fertilizers, and as a component in certain flame-retardant and ceramic applications where controlled nutrient release or pH stabilization is required.

Application

• Water Treatment Chemicals: Acts as a sequestering and scale inhibition agent in boiler and cooling water systems.
• Specialty Fertilizers & Nutrient Solutions: Serves as a source of highly soluble phosphorus and nitrogen for specific horticultural or hydroponic applications.
• Flame Retardant Synergist: Used in certain intumescent coatings and polymer formulations to enhance fire resistance.
• Ceramic & Glass Production: Functions as a fluxing agent and can modify the thermal properties of specialty glasses and ceramic glazes.
• Laboratory Reagent: Employed in analytical chemistry and research as a buffering agent or a standard.
• Metal Surface Treatment: Used in formulations for cleaning, phosphating, or corrosion protection of metal surfaces.
• Drilling Fluid Additive: Can be utilized in oilfield applications to control fluid rheology and clay stabilization.
