XRD Chemical is a professional Magnesium Sulfate Monohydrate manufacturer and supplier in China, offering high-purity MgSO₄·H₂O powder (98% min) for fertilizer, industrial, and feed applications.
Magnesium sulfate monohydrate is a white powder with one water of crystallization, positioned between the anhydrous form and the heptahydrate form (Epsom salt) in terms of magnesium concentration [citation:5]. It contains approximately 17% magnesium and 22% sulfur, making it a highly effective source of both essential nutrients for agricultural use. The monohydrate form offers a practical balance of higher magnesium content than heptahydrate while maintaining better handling properties than the highly hygroscopic anhydrous form.
The primary application of magnesium sulfate monohydrate is in agriculture as a magnesium and sulfur fertilizer, particularly in the production of compound fertilizers and for direct soil application to correct magnesium deficiency in crops [citation:1]. It is also used in animal feed as a source of bioavailable magnesium, in industrial processes, and as a raw material for producing other magnesium compounds. The monohydrate form is valued for its intermediate properties — more concentrated than heptahydrate but less moisture-sensitive than anhydrous magnesium sulfate [citation:5].
Why Choose XRD Magnesium Sulfate Monohydrate:
• 98% purity, white powder form
• Higher magnesium content (~17%) than heptahydrate (9.9%)
• Less hygroscopic than anhydrous — easier handling and storage
• Effective magnesium and sulfur source for compound fertilizers
• Feed grade available for livestock nutrition
• Also suitable for industrial and chemical applications
• Free samples available for evaluation
• COA and MSDS documents available for download
