What is What is Zinc Sulphate Heptahydrate Crystalline?
Zinc Sulphate Heptahydrate Crystalline (ZnSO₄·7H₂O), commonly known as "white vitriol," is an inorganic compound appearing as colorless transparent crystals or a white crystalline powder. It serves as a vital source of zinc, an essential micronutrient for both plants and animals. With a high solubility in water (960 g/L at 20°C), it ensures rapid nutrient absorption. Its applications span agriculture as a fertilizer, animal feed as an additive, and industries such as chemicals, electroplating, and pharmaceuticals.
Zinc Sulphate Heptahydrate Crystalline
 Core Features & Competitive Advantages

High Purity & Essential Nutrients
• Zinc Content ≥22%: Provides highly available zinc to swiftly correct deficiency symptoms in crops and livestock.
• Sulfur Content ≥11%: Supplies secondary nutrients that enhance nitrogen utilization and chlorophyll synthesis.
Superior Physical Properties
• High Solubility: Dissolves completely and rapidly in water, leaving no residue, making it ideal for fertigation and foliar sprays.
• White Crystalline Appearance: Indicates high purity and is easily identifiable for quality control.
Quality & Safety Assurance
• Controlled Heavy Metals: Pb≤10ppm, As≤5ppm, meeting international safety standards for feed and fertilizer applications.
• Compliance: Production processes align with industry standards like ISO 9001 and FAMI-QS for feed grade.

Stability & Functionality
Physical & Chemical Stability
• Stable Under Recommended Conditions: When stored in a cool, dry, and well-ventilated environment, the product maintains its crystalline form and efficacy. It is important to note that it gradually weathers in dry air.
• Decomposition at High Temperature: Loses water of crystallization above 200°C and decomposes at approximately 770°C, ensuring stability under normal application and storage temperatures.
Agronomic & Nutritional Functionality
• Enzyme Activation in Plants: Zinc is a key cofactor for enzymes involved in auxin synthesis and carbohydrate metabolism, directly influencing crop growth and yield.
• Essential for Animal Health: Supports robust immune function, skin integrity, and overall growth performance in livestock and poultry.

Application
Agriculture – Soil & Foliar Application
• Application: Apply 5-10kg per hectare via soil application or a 0.1%-0.3% solution for foliar spray.
• Benefit: Effectively prevents and corrects zinc deficiency in crops like corn (preventing "white bud") and citrus, improving yield and fruit quality.
Animal Feed – Nutritional Supplement
• Application: Homogeneously mix into premixes or complete feed at recommended dosages (e.g., 100-200mg/kg for swine).
• Benefit: Ensures optimal growth, supports immune system, and improves skin and hoof health in livestock.
Industrial Uses
• Application: Serves as a raw material in the production of electrolytes, zinc plating, and as a mordant in dyeing.
• Benefit: Provides a reliable and pure source of zinc ions for various chemical processes.

FAQ
What is the main difference between Zinc Sulphate Heptahydrate and Monohydrate?
A: The primary differences are zinc content and physical form. Heptahydrate contains about 22% Zn and is crystalline, ideal for fast-dissolving applications. Monohydrate (ZnSO₄·H₂O) has about 33% Zn, is typically a powder, and offers a higher concentration of zinc per unit weight.
Q2:  Is Zinc Sulphate Heptahydrate safe for my crops and animals?

A: Yes, when used as directed. It is an essential micronutrient source. However, always follow recommended application rates to avoid overexposure. Our product is manufactured with strict heavy metal controls for your safety.
Q3: How should I store this product to maintain its quality?

A:  Store in a cool, dry, and well-ventilated place. Keep the packaging sealed to prevent moisture absorption and weathering.
