Products Description
Magnesium sulphate anhydrous- MgSO4, is an inorganic salt that appears as a white crystalline powder. CAS number is 7487-88-9. This compound has extremely strong hygroscopic properties, rapidly absorbing moisture from the air, making it an important desiccant in various applications. It is highly soluble in water, glycerol, and ethanol, but insoluble in acetone. Its high solubility in water facilitates its dissolution and use in aqueous solutions.

Applicationsof Magnesium Sulfate Anhydrous:
1. Agriculture
Magnesium is an essential component of chlorophyll, the pigment used by plants in photosynthesis. Anhydrous magnesium sulfate is widely used as a fertilizer to correct magnesium deficiency in the soil. Crops with high magnesium demands, such as potatoes, peppers, tomatoes, and roses, greatly benefit from the application of anhydrous magnesium sulfate. It can be applied directly to the soil or used as a foliar spray to ensure plants receive sufficient amounts of this essential nutrient. It also assists plants in absorbing nitrogen and phosphorus, promoting overall growth and increasing productivity. Applying anhydrous magnesium sulfate to magnesium-deficient soils can significantly improve the quality and productivity of agricultural products.
2. Textile and Dyeing Industry
In the textile and dyeing industry, anhydrous magnesium sulfate plays a crucial role in the dyeing process. It is used as a dyeing aid to help dyes adhere to fabrics and improve the color of dyed products. It also acts as a weighting agent for silk and cotton fabrics, increasing their weight and giving them a more substantial feel. Furthermore, it is used in the production of various dyes and pigments, helping to ensure their stability and color intensity.
3. Other Industrial Applications:
Flame Retardant: Used in the manufacture of flame-retardant materials, such as flame-retardant cement. When mixed with cement, it increases the fire resistance of the final product, making it suitable for buildings and structures that are difficult to protect against fire.
Paper Manufacturing: The paper industry uses anhydrous magnesium sulfate as a filler and sizing agent. It improves the strength and smoothness of the paper, making it more durable and suitable for various printing and writing applications.
Leather Processing: Used in leather coating processes, it helps improve the stability and quality of the leather. It can also be used to adjust the pH of the leather matrix for proper processing.
Leather Processing: Used in leather coating processes, it helps improve the stability and quality of the leather. It can also be used to adjust the pH of the leather matrix for proper processing. Environmental protection: In wastewater treatment, anhydrous magnesium sulfate can be used to pulverize heavy metals and other pollutants, helping to purify the water so that it can be safely disposed of or reused.
