Description

Ammonium Magnesium Phosphate is an inorganic salt compound with significant industrial and specialty chemical utility. Its unique combination of ammonium, magnesium, and phosphate ions makes it valuable as a controlled-release nutrient source and a functional material in various processes. This product is essential for manufacturers in the fertilizer, flame retardant, and specialty ceramics industries seeking a specific phosphate compound. We supply high-purity grades to meet diverse technical and commercial requirements.

Application

• Controlled-Release Fertilizers: Acts as a slow-release source of nitrogen, magnesium, and phosphorus for specialty agricultural and horticultural applications.
• Flame Retardant Additive: Used as a component in flame-retardant formulations for plastics, textiles, and coatings, where it promotes char formation.
• Ceramic and Glass Production: Serves as a precursor or additive in the manufacture of specialty glasses, ceramics, and enamel frits.
• Nutrient Supplement: Employed in the production of mineral supplements and feed additives for animal nutrition.
• Laboratory Reagent: Utilized as a analytical reagent or precipitating agent in chemical analysis and research laboratories.
• Wastewater Treatment: Functions as a precipitating agent for the recovery of phosphate and ammonium from industrial effluents.
• Dental and Biomedical Cements: Investigated for use in forming biocompatible cements and materials.
