Description

Tri-Ammonium Phosphate Trihydrate is a high-purity, water-soluble inorganic salt that serves as a critical source of both nitrogen and phosphorus. This compound is valued for its stability and consistent performance in demanding industrial and technical processes. It is an essential raw material for manufacturers in the fertilizer, flame retardant, and specialty chemical synthesis sectors, where precise nutrient content and chemical reliability are paramount.

Application

• Fertilizer Industry: Used as a high-efficiency, water-soluble phosphorus and nitrogen source in specialty fertilizers and nutrient solutions for hydroponics and fertigation.
• Flame Retardants: Acts as an effective intumescent flame retardant and synergist in coatings, plastics, and textiles.
• Industrial Water Treatment: Functions as a corrosion inhibitor and scale prevention agent in cooling water and boiler water systems.
• Laboratory & Analytical Reagents: Serves as a buffer component and analytical standard in various chemical and biological research applications.
• Food & Feed Additives: Employed as a nutrient supplement and emulsifying salt in specific food processing and animal feed formulations (subject to appropriate grade availability).
• Ceramics & Metallurgy: Used in the production of specialty glasses, ceramics, and as a component in metal surface treatment processes.

Quality Control

Our Tri-Ammonium Phosphate Trihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, composition, and physical properties. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, heavy metal content, and loss on drying. We can supply material compliant with technical, reagent, and food-grade standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and degradation. Keep away from incompatible materials such as strong acids.
