Description

Manganese(II) Sulfate Tetrahydrate is a vital inorganic salt that serves as a primary source of bioavailable manganese ions. This compound is essential for numerous industrial and agricultural processes due to its high solubility and stability. It is a critical raw material for manufacturers in the fertilizer, animal nutrition, ceramics, and chemical synthesis sectors, where consistent quality and reliable supply are paramount.

Application

• Agricultural Micronutrient Fertilizer: A key component in liquid and granular fertilizers to correct manganese deficiencies in crops, promoting chlorophyll synthesis and enzyme activation.
• Animal Feed Premix: An essential trace mineral additive in poultry, swine, and cattle feed to support bone development, reproduction, and metabolic functions.
• Electrolytic Manganese Dioxide (EMD) Production: Serves as a fundamental electrolyte feedstock in the manufacture of EMD for dry-cell batteries.
• Ceramics and Glazes: Used as a colorant to produce pink and brown hues in tiles, pottery, and porcelain.
• Chemical Synthesis: Acts as a catalyst precursor and a manganese source in various organic and inorganic chemical manufacturing processes.
• Water Treatment: Employed in certain oxidation and precipitation processes for wastewater treatment.
• Nutritional Supplements: Used in the formulation of human dietary supplements under appropriate pharmaceutical-grade specifications.
