Purity 99%: Potassium Sulfate with 99% purity is used in high-efficiency fertilizer production, where it ensures maximum nutrient availability for crops. Particle Size <100 μm: Potassium Sulfate with particle size below 100 micrometers is used in foliar spray formulations, where it provides rapid plant nutrient uptake. Low Chloride Content: Potassium Sulfate with low chloride content is used in chloride-sensitive crop fertilization, where it prevents salt stress and crop yield loss. Granular Form: Granular Potassium Sulfate is used in broad-acre application systems, where it allows uniform nutrient distribution and easy mechanical spreading. Water Solubility >97%: Potassium Sulfate with water solubility over 97% is used in fertigation systems, where it ensures effective delivery through irrigation lines. Melting Point 1067°C: Potassium Sulfate with a melting point of 1067°C is used in glass manufacturing processes, where it improves glass clarity and stability. Stability Temperature up to 300°C: Potassium Sulfate stable up to 300°C is used in thermal processing of specialty ceramics, where it maintains structural integrity under heat. Molecular Weight 174.26 g/mol: Potassium Sulfate with molecular weight 174.26 g/mol is used in analytical reagent preparation, where it provides precise stoichiometric calculations. pH (1% Solution) 6.5-7.5: Potassium Sulfate with pH 6.5-7.5 in 1% solution is used in sensitive horticultural environments, where it supports optimal root growth without altering soil pH. |
| Packing | Potassium Sulfate is packaged in a 25 kg white polyethylene bag, labeled with product name, purity, hazard symbols, and manufacturer details. |
| Container Loading (20′ FCL) | 20′ FCL (Full Container Load) typically carries 26 metric tons of Potassium Sulfate, packed in 25 kg or 50 kg bags. |
| Shipping | Potassium sulfate is typically shipped in tightly sealed, moisture-resistant bags or containers to prevent contamination and caking. It should be stored in a cool, dry, well-ventilated area, away from incompatible substances. Transport complies with standard regulations, as it is non-hazardous, ensuring safe handling and delivery to the destination. |
| Storage | Potassium sulfate should be stored in a cool, dry, well-ventilated area away from moisture and incompatible substances such as strong acids. Keep the container tightly closed and properly labeled. Avoid storing near combustible materials. Use corrosion-resistant containers to prevent contamination. Ensure the storage area is equipped with appropriate spill containment procedures and safety equipment. Store away from food and feed products. |
| Shelf Life | Potassium sulfate has an indefinite shelf life if stored in a cool, dry place, tightly sealed, and protected from moisture. |
