Monoammonium Phosphate Powder is a high-purity phosphate raw material developed for industrial manufacturers that require stable phosphorus and nitrogen sources with controlled impurity levels. With the chemical formula NH₄H₂PO₄ and molecular weight of 115.03, it is supplied in white crystalline powder form and offers excellent water solubility for different formulation and processing requirements.
For industrial procurement, consistency is often more important than simply purchasing a high-purity chemical. We focuses on stable composition, controlled moisture, low insoluble matter, trace impurity management, uniform physical properties, and batch-to-batch consistency to help manufacturers reduce raw material fluctuations during continuous production.
Industrial phosphorus compounds are used in formulations where chemical purity and predictable processing behavior can directly influence the quality of finished products. AOLANSU MAP is therefore manufactured with particular attention to phosphorus content, nitrogen content, chloride, sulfate, heavy metals, moisture, and particle size.
The material contains approximately 11.5% nitrogen and 60.5% P₂O₅, providing a concentrated source of ammonium and phosphate ions. The main content is controlled at ≥98.0%, while moisture and other impurities are maintained within defined limits.
Excellent Water Solubility
The material dissolves readily in water, making it convenient for preparing liquid formulations, concentrated solutions, reaction systems, and other industrial mixtures. Its solubility also supports efficient processing where rapid dissolution is required.
Consistent Physical Form
Powder grades can be supplied according to customer processing requirements. Uniform particle distribution helps improve feeding, weighing, mixing, and automated dosing during industrial production.
For applications such as flame-retardant formulations, specialty chemical production, and industrial treatment systems, excessive chloride, sulfate, insoluble matter, or heavy metals can affect formulation stability.
The value of this phosphate raw material is determined not only by chemical composition but also by how consistently it performs in downstream manufacturing. We supplies different physical specifications for applications requiring controlled phosphorus input.
MAP can serve as a phosphorus-containing component in intumescent flame-retardant systems. During thermal decomposition, phosphorus-containing compounds can participate in protective char formation, making the material suitable for selected plastic, coating, wood, textile, and construction-material formulations.
As a source of ammonium and phosphate ions, MAP can be incorporated into the production of phosphate-based chemicals and specialty formulations. Its defined chemical composition helps manufacturers maintain more predictable reaction and formulation conditions.
Phosphate compounds are used in selected industrial water-treatment formulations for nutrient adjustment, water chemistry management, and related treatment processes. The appropriate grade and dosage should be determined according to the specific treatment system.
Phosphate-based raw materials can be used in selected metal-treatment and surface-treatment formulations. AOLANSU provides controlled specifications for industrial users that need consistent chemical inputs for formulation development.
MAP may also be incorporated into certain adhesive, coating, mineral-based, and construction-material formulations where phosphorus compounds are required as functional components. Final formulation compatibility should be verified through customer-side testing.
When purchasing phosphate raw materials in bulk, a small change in impurity levels can create problems in downstream production. Excess moisture may affect storage and feeding, insoluble matter can influence solution clarity, while uncontrolled trace metals may interfere with sensitive formulations.

AOLANSU uses a controlled manufacturing route designed to maintain chemical composition and physical consistency from one production batch to the next.
Phosphoric acid and ammonia-based raw materials are inspected before production. Purity, moisture, and impurity indicators are checked to reduce variations entering the production process.
The neutralization reaction is controlled according to concentration, temperature, feeding ratio, and process conditions. Accurate reaction control helps establish the required ammonium phosphate composition.
The crystallized material is dried under controlled conditions to reduce moisture. Screening and particle processing are then performed according to the required powder or granular specification.
Before shipment, production batches are tested for main content, nitrogen, P₂O₅, moisture, chloride, sulfate, heavy metals, particle size, and appearance. Products are released only after meeting the agreed specification.
Monoammonium Phosphate Powder can be supplied in powder form. Buyers can select the physical specification according to their feeding, dissolution, mixing, and packaging processes.
