What is Magnesium Nitrate Hexahydrate? Magnesium Nitrate Hexahydrate (chemical formula Mg(NO₃)₂·6H₂O) is a chemical compound that is commonly used in agricultural, industrial, and chemical applications. It is a crystalline substance, usually colourless or white, highly soluble in water. Also known as Magnesium Nitrate 6-Hydrate and Magnesium Dinitrate Hexahydrate, this product provides a combination of magnesium and nitrogen, both essential nutrients for plant growth. It is widely valued for its role in fertilisers, pyrotechnics, water treatment, and various chemical processes.

Consistent Quality: We use only carefully sourced Magnesium Nitrate Hexahydrate, ensuring reliable and consistent performance for a wide range of applications.

Frequent Uses

Agricultural Fertilisers
Magnesium Nitrate Hexahydrate is widely used in the agricultural sector, particularly in fertilisers. It is a valuable source of magnesium and nitrogen, which are essential for healthy plant growth.

Concrete and Cement
In the construction industry, it is sometimes included in mixtures to enhance the setting time and strength of the material, especially in applications where rapid hardening is required or in challenging environmental conditions.
