Product Overview

Magnesium sulfate is a versatile inorganic compound used in agriculture, animal feed, pharmaceuticals, and industrial applications. It is available in two forms: Magnesium Sulphate Monohydrate (MgSO₄·H₂O) and Magnesium Sulphate Heptahydrate (MgSO₄·7H₂O). Both serve as essential sources of magnesium and sulfur, which are critical nutrients for plant growth, livestock health, and various industrial processes.

Industrial Applications

1. Agriculture & Fertilizers

• Used as a magnesium and sulfur fertilizer to improve crop yield, photosynthesis, and chlorophyll production.
• Prevents magnesium deficiency in soil, ensuring healthier plant growth.
• Applied via soil application, foliar spray, or fertigation.

2. Animal Feed Supplements

• Added to livestock and poultry feed as a magnesium supplement to support bone development, enzyme activation, and metabolic functions.
• Helps prevent grass tetany in cattle and sheep.

3. Pharmaceuticals & Healthcare

• Used in Epsom salt (Magnesium Sulphate Heptahydrate) for muscle relaxation, pain relief, and stress reduction.
• Acts as a laxative and electrolyte replenisher in medical treatments.

4. Water Treatment

• Used in wastewater treatment plants to remove heavy metals and improve water quality.
• Enhances biological treatment efficiency in industrial wastewater systems.

5. Industrial Applications

• Used in the textile industry as a dyeing and finishing agent.
• Helps in paper production by improving pulp processing.
• Acts as a coagulant in the production of fireproofing materials.

Differences Between Magnesium Sulphate Monohydrate & Heptahydrate

• Magnesium Sulphate Monohydrate (MgSO₄·H₂O) has a higher magnesium concentration (≥ 16%), making it more efficient for agricultural and feed applications.
• Magnesium Sulphate Heptahydrate (MgSO₄·7H₂O) contains more water content and is commonly used in pharmaceuticals, cosmetics, and water treatment.
