Magnesium Sulphate Monohydrate (Kieserite)
Magnesium sulfate monohydrate (MgSO₄·H₂O) is a cost-effective agricultural magnesium and sulfur fertilizer with stable physical and chemical properties and good water solubility. It will not change the original pH value of soil after application. It effectively solves magnesium deficiency problems in soil and crops, applicable for base fertilizer and top dressing, and significantly improves crop yield and quality.

Applications & Industries
- agriculture
- fertilizer
Our magnesium sulfate monohydrate is produced by advanced purification, crystallization and drying processes, with white pure appearance, no agglomeration, low impurity content and stable chemical performance. Compared with heptahydrate magnesium sulfate, it has higher magnesium content, lower water content and better storage stability, not easy to deliquesce in humid environment. The product has fast water solubility and high activity, which can be quickly absorbed and utilized by crops and industrial raw materials. Available in powder and granular specifications, supporting customized packaging and purity standards. Widely used as high-efficiency magnesium fertilizer for crops and fruit trees, feed additive for livestock breeding, chemical raw material for magnesium salt synthesis, building material additive and textile auxiliary agent. With high purity, long storage period and significant cost advantages, it is a preferred magnesium salt product for agricultural and industrial markets.

Frequently Asked Questions
Which magnesia products do you supply?
Caustic calcined magnesia (CCM, MgO 85–95%), dead burnt magnesia (DBM, MgO 96–99%), electro-fused magnesia (MgO ≥ 98%), high purity magnesia sand, plus magnesium sulphate heptahydrate (99.5%) and monohydrate.
What is the difference between caustic calcined, dead burnt and fused magnesia?
CCM is calcined at 700–1000 °C and is chemically reactive, used for magnesium cement, desulphurisation and feed. DBM is sintered above 1600 °C for high density and is the base for refractory bricks. Fused magnesia is arc-melted above 2800 °C, giving the largest crystals and the best slag resistance.
Can I get custom MgO content and particle size?
Yes. MgO can be tailored across 85%, 90%, 92%, 94%, 95%, 96%, 97%, 98% and 99%, with powders from 120 mesh to granules of 0–1 mm, 1–3 mm, 3–5 mm or larger.
Do you provide third-party test reports?
Yes. We test every batch in-house and can arrange SGS or other third-party inspection on request, at the buyer's cost.
