Detail Information

　　98% Anhydrous Magnesium Sulfate (chemical formula MgSO?, CAS No. 7487-88-9) is a white powder or crystalline powder chemical product with a purity of 98%. It possesses strong hygroscopicity and high solubility, and is widely used in scientific research, industry, agriculture, and other fields. 

      The following is a detailed introduction:

　　1. Core Characteristics

　　 Physical Properties: Melting point is 1124℃ (it decomposes at this temperature); relative density is 2.66; refractive index is 1.56; readily soluble in water, the aqueous solution is neutral; also soluble in glycerol and ethanol, slightly soluble in ethanol, insoluble in acetone; highly hygroscopic, it can quickly absorb moisture from the air, a characteristic that makes it an excellent desiccant.

　　 Quality Advantages: As a high-purity product, it has extremely low impurity content. Harmful impurities such as nitrates, chlorides, and heavy metals are controlled at very low levels (e.g., heavy metals, calculated as Pb, ≤0.001%). It is also less corrosive than other salts, and being naturally derived, it is environmentally friendly. No special protection is required during storage and transportation, making it convenient and safe.

　　2. Main Application Areas

　　Scientific Research: Commonly used in AR-grade 98% anhydrous magnesium sulfate for biochemical research and synthesis experiments. It can also be used as an analytical reagent to assist in experiments, such as adjusting the reaction system environment in some chemical analyses. Common packaging includes small sizes such as 25g, 250g, and 500g.

　　Industrial Applications: Its uses are very diverse. In the dyeing and printing industry, it serves as a color developer for blue dyes, an alkali absorber in black dye liquor to adjust pH, and a fixing agent to improve dye uniformity and color fastness. In the papermaking industry, it acts as a filler to optimize paper quality. In the building materials sector, it can be used as a cement fire retardant to enhance fire resistance and as an additive in building materials such as anhydrous gypsum flooring and lightweight boards. Furthermore, it can be used as a catalyst carrier in chemical synthesis or in the production of thermoplastic plastics such as ABS and expandable polystyrene.

　　In agriculture and water treatment: In agriculture, it can be used to formulate high-efficiency Magnesium fertilizers, supplementing the soil with magnesium and sulfur to support crop photosynthesis and promote growth. In water treatment, it can regulate water hardness, assist in the removal of heavy metal ions, improve wastewater treatment efficiency, and ensure effluent quality.

　　3. Common Specifications and Storage

　　Packaging Specifications: Research-grade products are typically packaged in small sizes, ranging from 25-500 grams per bottle; industrial and agricultural products are often packaged in 25 kg bags or 25 kg drums. Some manufacturers also offer larger packaging such as 200 kg. Customized particle sizes and moisture-proof packaging are also available.

　　Storage Requirements: Store in a cool, dry, and well-ventilated environment. Keep containers tightly closed and away from incompatible substances to prevent clumping due to moisture absorption, which can affect dosage control and efficacy.

　　Core Advantages

　　Cost Optimization: High concentration of active ingredient, reducing dosage by 40% compared to Magnesium Sulfate Heptahydrate, and transportation costs by over 50%. Long-term procurement can significantly reduce overall water treatment costs.

　　Stable Quality: Utilizes high-quality raw materials and refining processes, resulting in low impurity content.

　　Customized Services: Can provide products with different particle sizes (80-200 mesh) and packaging specifications (25kg/bag, 50kg/bag, ton bag) according to customer needs, supporting OEM/ODM production to adapt to enterprise production processes.

　　Environmental Compliance: Products meet industrial water treatment chemical environmental standards, with no secondary pollution after reaction, helping enterprises meet environmental policy requirements and avoid environmental penalties. ?
