Magnesium Sulfate Monohydrate

Usage Areas, Benefits, Sectors

Discover the uses of magnesium sulfate monohydrate in the agriculture, feed, food, textile, ceramics, chemical, construction, water treatment and aquarium sectors.

What is Magnesium Sulfate Monohydrate?

Magnesium sulfate monohydrate (MgSO₄·H₂O) is known by its mineral name kieserite. It is a water-soluble, white crystalline magnesium salt. It has a higher magnesium content than its heptahydrate form. It is preferred as a reliable mineral source in the agriculture, feed, food, textile, ceramics, chemistry, construction, water treatment and aquarium sectors.
Main Areas of Use

1) Agriculture (Kieserit – Fertilizer and Soil Regulation)

• Source of magnesium and sulfate: It plays a critical role in photosynthesis and enzyme activities in plant development.

• Soil applications: It is used to eliminate magnesium deficiency in alkaline soils.

• Organic agriculture: It has forms in accordance with the European Union organic agriculture legislation.

2) Feed Industry (Animal Nutrition)

• Mineral additive: Prevents magnesium deficiency in farm animals and supports metabolism.

• In premixes: It is used to prevent deficiency problems such as grass tetany (hypomagnesemia).

3) Food Industry (E518)

• Additive: Identified by the code E518 in the European Union.

• Areas of use: Boiling salt in beer production, coagulant in tofu making, stabilizer in mineral-added foods.

4) Textile Industry

• Dyeing and finishing: It facilitates the adhesion of dyestuffs to the fibers and increases process efficiency.

• Bleaching additive: It plays a stabilizing role in some peroxide bleaching processes.

5) Ceramics and Glass

• Melting promoter: Provides flow control in ceramic clay, is a glaze and engobe additive.

• Durability enhancer: Used to increase the strength of products.

6) Chemistry and Industrial Applications

• Reagent and catalyst: Used in various chemical syntheses.

7) Construction and Construction Chemicals

• Special cements based on magnesia: It is involved in the production of oxysulphate binders together with MgO.

• Aggregate tests: Its solution is used in durability tests of aggregates according to ASTM C88 standard.

8) Water Purification and Aquarium

• Purification processes: Contributes to phosphorus removal and precipitation of some heavy metals.

• Reef aquariums: Used for magnesium balance and calcium carbonate stability.
