Zibo Dingqi Chemicals Co., Ltd. is one of the most experienced manufacturers and suppliers of ferrous sulfate monohydrate powder in China. Welcome to wholesale high quality ferrous sulfate monohydrate powder made in China here from our factory. For price consultation, contact us.
Product Overview
Ferrous Sulfate Monohydrate Powder is an iron(II) salt containing one molecule of crystallization water per formula unit.
Compared to heptahydrate alternatives, the monohydrate structure delivers a higher theoretical iron concentration (above 30 percent) per unit weight. This higher assay efficiency reduces bulk shipping weights, storage footprints, and material handling overhead for industrial end-users.

Product Advantages
High Theoretical Iron Efficiency
Due to the monohydrate crystal structure containing only one water molecule per formula unit, the material delivers a concentrated iron assay exceeding 30.0 percent. This high purity reduces the total tonnage required for formulation compared to hydrated alternatives, directly lowering freight and inventory storage overhead.
Controlled Physical Characteristics
Produced through optimized crystallization and drying processes, the powder maintains a uniform 20 to 100 mesh particle distribution. This prevents excessive dust generation during unloading while ensuring consistent dissolution rates in industrial mixing tanks.
Batch Traceability and Consistency
Every production lot undergoes rigorous multi-stage laboratory testing to verify free acid levels, moisture caps, and insoluble matter thresholds. Standardized internal quality audits ensure dependable batch-to-batch repeatability for large-scale manufacturing operations.
Core Industrial Applications
Fertilizer and Agricultural Input Manufacturing
Function: Serves as a vital micronutrient and iron source in specialized fertilizer blends and soil amendment formulations.
Key Evaluation Metrics: Total iron assay, heavy metal impurity thresholds, and compatibility with granular or liquid mixing equipment.
Industrial Chemical Synthesis
Function: Acts as a chemical intermediate and reducing agent for the production of iron-based pigments, catalysts, and specialized chemical derivatives.
Key Evaluation Metrics: Free acid levels, chemical reactivity, and consistent batch-to-batch assay purity.
Industrial Water Treatment Systems
Function: Utilized in specific industrial effluent treatments for chemical reduction, heavy metal precipitation, and targeted coagulation processes.
Key Evaluation Metrics: Solubility rate, oxidation state (Fe2+ retention), and compatibility with existing pH and dosing systems.
Material Handling and Storage Behavior
Understanding the physical behavior of iron sulfate monohydrate ensures safe handling and prevents processing bottlenecks:
Hygroscopic Nature: The powder absorbs moisture from ambient air, which can cause caking or discoloration if exposed. Containers must remain tightly sealed until ready for use.
Oxidation Control: Prolonged exposure to warm, humid air can oxidize ferrous iron (Fe2+) into ferric iron (Fe3+), resulting in a brownish surface discoloration and altered chemical reactivity.
Storage Environment: Store in a cool, dry, well-ventilated structure away from strong oxidizing agents and moisture sources.
Quality Documentation and Traceability
Industrial buyers require complete transparency to satisfy internal quality management frameworks:
Certificate of Analysis (COA): Issued per production batch, confirming exact assay results, moisture levels, and impurity values.
Safety Data Sheet (SDS): Details safe handling procedures, personal protective equipment requirements, and spill response protocols.
Technical Data Sheet (TDS): Provides comprehensive physical properties for engineering and R&D verification.
Packaging and Supply Options
Standard Packaging: Available in 25 kg woven polypropylene bags featuring inner polyethylene liners, or 1,000 kg industrial jumbo bags.
Custom Requirements: Special packaging configurations, palletization, and labeling options can be coordinated according to destination port requirements.
FAQ
Q: What is the difference between ferrous sulfate monohydrate and heptahydrate powders?
A: The primary difference lies in the water of crystallization. Monohydrate powder contains one water molecule per formula unit, yielding a higher iron concentration by weight and improved resistance to caking compared to heptahydrate, which contains seven water molecules.
Q: How does moisture affect the storage of this powder?
A: The material is hygroscopic and tends to absorb ambient humidity. Storing the product in airtight packaging within a dry, temperature-controlled environment prevents clumping and surface oxidation of ferrous ions into ferric ions.
Q: Can particle size distribution be customized for specific manufacturing lines?
A: Yes. While standard production yields a 20 to 100 mesh distribution suitable for most applications, specific sizing parameters can be evaluated based on the customer's mechanical feeding and dissolution setup.
Q: What documentation is supplied with commercial shipments?
A: Each shipment is accompanied by a batch-specific Certificate of Analysis, a Technical Data Sheet, and a Safety Data Sheet outlining safe handling procedures and regulatory compliance details.
