    Product Overview

    Diammonium Phosphate (DAP) 21-53-0 Tech Grade is a high-purity, fully water-soluble phosphate material designed for industrial processing, fertilizer blending, and advanced fertigation systems. Unlike conventional granular Diammonium Phosphate used in bulk agriculture, this Tech Grade Diammonium Phosphate (DAP) is produced in crystalline form with strict control over solubility, impurity levels, and stability in solution.

    This product is developed to meet the growing demand for water-soluble phosphate sources in modern agricultural and industrial applications, where rapid dissolution, compatibility, and consistency are critical. As a premium Diammonium Phosphate (DAP), it provides a reliable source of nitrogen and phosphorus for precision nutrient delivery systems.

    Production Process and Quality Control

    Tech Grade Diammonium Phosphate (DAP) is manufactured through a controlled neutralization process using purified phosphoric acid and ammonia. Compared with standard agricultural-grade Diammonium Phosphate, the Tech Grade DAP undergoes additional purification and crystallization steps to ensure:

    • Lower insoluble content
    • Higher purity and clarity in solution
    • Reduced heavy metal impurities
    • Stable chemical composition

    The result is a Diammonium Phosphate (DAP) that performs consistently in high-demand applications, especially where filtration systems, injectors, or mixing tanks are sensitive to impurities.

    Key Performance Features

    Diammonium Phosphate (DAP) 21-53-0 Tech Grade is engineered for performance rather than bulk supply. Its core advantages include:

    • Fully water soluble, ensuring rapid dissolution without residue
    • Low insoluble matter, reducing the risk of clogging in irrigation or dosing systems
    • Stable solution behavior, suitable for tank mixing and liquid formulations
    • High nutrient concentration, providing efficient phosphorus and nitrogen delivery
    • Consistent particle structure, improving handling and storage stability

    Application Scenarios

    1. Fertigation Systems

    In modern irrigation systems, Diammonium Phosphate (DAP) is used as a soluble nutrient source for drip irrigation and greenhouse cultivation.

    2. Fertilizer Blending

    As a raw material, Diammonium Phosphate (DAP) is used in the production of NPK water-soluble fertilizers.

    3. Industrial Applications

    Tech Grade Diammonium Phosphate (DAP) can be used in flame retardants, fermentation nutrients, and chemical intermediates.

    4. Foliar & Precision

    Diammonium Phosphate (DAP) can be integrated into foliar nutrition programs for targeted crop nutrient delivery.

    Nutrient Composition

    Nitrogen (N) ≥ 21%
    Phosphorus (P₂O₅) ≥ 53%
    Water Solubility 100%
    pH (1% solution) 7.5–8.5

    Frequently Asked Questions (FAQ)

    Q What is Diammonium Phosphate (DAP) 21-53-0 Tech Grade?
    It is a high-purity, fully water-soluble crystalline phosphate material designed for specialized agricultural fertigation, liquid fertilizer blending, and high-performance industrial processes.
    Q How does Tech Grade DAP differ from standard agricultural-grade DAP?
    Unlike standard granular agricultural DAP, Tech Grade DAP is produced in crystalline form and undergoes additional purification and crystallization steps to ensure lower insoluble content, reduced heavy metal impurities, and maximum clarity in solution.
    Q Will this product clog my irrigation or fertigation systems?
    No. With a water-insoluble matter level of ≤ 0.1% (often reaching ≤ 0.05%), it offers rapid, residue-free dissolution, making it highly compatible with sensitive drip irrigation systems, injectors, and filtration equipment.
    Q What are the industrial applications of Tech Grade Diammonium Phosphate?
    Beyond agricultural fertigation, it is widely utilized as a raw material for flame retardants, fermentation nutrients, and various chemical intermediates due to its high purity and stable composition.
    Q What packaging options do you offer for supply?
    Our standard packaging options include 25 kg bags and Jumbo bags (1 MT). We also offer customized packaging solutions to suit specific industrial or logistics requirements.
