Ammonium sulfate, a mineral salt with diverse applications across various industries, finds its primary utility in the agricultural sector for the synthesis of nitrogenous fertilizers, characterized by the chemical formula (NH4)2SO4.
As an integral contributor to meeting industrial demands, numerous suppliers engage in the procurement and distribution of ammonium sulfate. Among these, Petro Barous Company has emerged as a global player, demonstrating a commitment to excellence and a steadfast dedication to meeting the needs of customers worldwide. This has positioned Petro Barous prominently in the global supply chain for ammonium sulfate and other chemical products.
Guide to Procuring Ammonium Sulfate
Ammonium sulfate typically manifests as a white solid, available in powder, granular, or crystalline forms. The granulation of this compound holds significant importance in the purchasing process. Prospective buyers are advised to request the chemical analysis sheet from manufacturers and consider the intended application, as it influences the granulation requirement.
Assessing Product Quality
The quality of ammonium sulfate is discerned through its odorless nature and key visual and sensory attributes such as color, appearance, and smell. When purchasing in bulk, attention should be directed first to the grain size, followed by a thorough examination of appearance to ensure a non-lumpy consistency.

Production Methods
Ammonium sulfate is a by-product derived from coke ovens in the presence of sulfuric acid, as indicated by the reaction: 2 NH3 + H2SO4 → (NH4)2SO4. Alternatively, it can be obtained from gypsum through the reaction: (NH4)2CO3 + CaSO4 → (NH4)2SO4 + CaCO3.
Applications Across Industries
The applications of ammonium sulfate span various industries:
Agriculture: Preparation of nitrogen fertilizers, additives in the production of insecticides, herbicides, and fungicides.
Food Industry: Adjusting the acidity of flour for bread production.
Water Refinery: Exhibits antiseptic properties.
Chemical Industry: Synthesis of ammonium salts, production of flame retardants.
Medical: Raw material in the production of certain vaccines.
Wood Industry: Acts as a preservative.
Packaging and Storage
Ammonium sulfate is available in 50, and 1000 kg jumbo bags. Bulk orders can be facilitated with suitable transportation. Proper storage involves keeping the packages away from moisture sources in cool and well-ventilated warehouses. Additionally, bags should be kept away from oxidizing materials, heat, and sparks, with the lids tightly sealed after each use.
Safety Guidelines
Handling ammonium sulfate requires appropriate protective gear, including work clothes, gloves, goggles, and masks, as it may cause skin and respiratory allergies.
Competitive Pricing
Maintaining product quality through chemical analysis is crucial whether procuring ammonium sulfate for export or domestic use. Currently, Iran boasts renowned suppliers, with Petro Barous offering competitive prices and guaranteed quality, particularly in the agriculture sector for fertilizer production.
