Product Introduction: This product is high-purity magnesium sulfate monohydrate, available as white crystal granules or powder. Compared to magnesium sulfate heptahydrate, it has lower water content, higher magnesium nutrient content, and excellent moisture-proof and anti-caking properties. It is available in industrial grade and agricultural fertilizer grade, possessing stable physical and chemical properties and good water solubility. It is widely used in chemical production, building materials processing, and crop magnesium supplementation fertilization. It serves as a bulk essential raw material for magnesium and sulfur elements, offering strong versatility and low storage and transportation costs.
