Learn About Ammonium Sulfate
Ammonium sulfate is a classic nitrogen and sulfur fertilizer with relatively focused applications; its primary use is as an agricultural fertilizer, though it is also used in industrial, pharmaceutical, and food sectors.
Physical and Chemical Properties of Ammonium Sulfate
Basic Appearance: Qualified ammonium sulfate appears as colorless transparent monoclinic crystals or uniform white crystalline particles. After our precision controlled crystallization, the finished products feature neat crystal morphology, high whiteness and low fine powder rate, with no caking or impure particles, meeting international commercial trading standards.
Solubility Characteristics: It possesses good water solubility and dissolves rapidly in water to form weak acidic solution, while being almost insoluble in ethanol, acetone and other organic solvents. Its solubility changes gently with temperature, which enables stable and controllable isothermal crystallization and high-efficiency solid-liquid separation.
Stability & Hygroscopicity: Ammonium sulfate has low hygroscopicity compared with nitrate products and maintains stable physical properties under normal storage conditions. It is non-deliquescent in dry environments and only slightly absorbs moisture under high humidity, ensuring convenient long-term storage and cross-border transportation.
Thermal Decomposition Performance: The product features stable low-temperature performance and starts gradual decomposition above 280℃, releasing ammonia gas and forming ammonium bisulfate. The controllable thermal stability ensures safe drying, granulation and packaging in industrial production.
Core Product Traits: Our customized ammonium sulfate features low free acid, low moisture, high nitrogen and sulfur content, and uniform particle gradation. We support personalized indexes for agricultural fertilization, industrial raw material and chemical auxiliary applications.
