Magnesium Sulfate Anhydrous

Areas of Use, Benefits, Sectors

Explore the uses and advantages of magnesium sulfate anhydrous in agriculture, feed, food, chemicals, ceramics, construction, plastics, and water treatment.

What is Magnesium Sulfate Anhydrous?

Magnesium sulfate anhydrous (MgSO₄) is a magnesium salt in the form of a white powder that does not contain water molecules in its crystalline structure. It has a higher magnesium content (20.2% Mg) compared to its heptahydrate and monohydrate forms. This property makes it widely used in agriculture, feed, food, chemical, ceramics, construction, plastics, and water treatment industries.

Main Areas of Application

1) Agriculture (Plant Nutrition and Fertilizers)

• Source of magnesium: Provides magnesium necessary for photosynthesis and enzymatic activity in plants.

2) Feed Industry (Animal Nutrition)

• Mineral supplement: Provides magnesium support in ruminant and poultry feed, regulating metabolism.

• In premixes: Thanks to its concentrated form, it offers effectiveness at low doses.

3) Food Industry (E518)

• Food additive: Identified by the code E518 in the European Union.

• Applications: It serves as a culture medium in yeast and beer production, a stabilizer in mineral-fortified foods, and a salt substitute in some products.

4) Chemical and Industrial Applications

• Reagents and catalysts: Used in organic synthesis and various industrial processes.

• Desiccant: Due to its hygroscopic nature, it removes moisture from solvents, making it a common desiccant.

5) Ceramics and Glass Industry

• Additive: Ensures flow balance in ceramic clays and facilitates melting.

• Product quality: Improves the durability and surface quality of ceramic and glass products.

6) Construction and Building Chemicals

• MOS cement additive: Used as a binder component in specialty magnesium-based cement systems.

• Durability tests: Magnesium sulfate solutions are used in the strength tests of aggregates (ASTM C88).

7) Water and Wastewater Treatment

• Coagulant facilitator: Contributes to the precipitation of phosphorus and some pollutants.

• Aquarium applications: Used to balance magnesium levels in marine aquariums.
