Anhydrous magnesium sulfate is an inorganic compound with the molecular formula MgSO4, crystalline in a colorless rhombic crystal system, and a white powder. Soluble in water, ethanol, glycerol, insoluble in acetone. Used in the pharmaceutical and printing and dyeing industries, it can also be used as a desiccant, feed, fertilizer, or composite fertilizer, and is also a raw material for the production of magnesium oxide.

1. Used in the pharmaceutical industry and printing and dyeing industry. In the printing and dyeing industry, it is used as a color developing salt for blue dyes and as an alkali absorbent in black liquor to ensure uniform dyeing with a pH value between 6 and 7. It can also be used as a cement fire retardant, paper filling agent, and weighting agent for textiles.

2. Used as an analytical reagent and desiccant. Due to its fast absorption of water and being a neutral compound, it does not react chemically with various organic substances, making it a commonly used desiccant. Especially for organic compounds that cannot be dried with anhydrous calcium chloride, it is commonly used for drying.

3. Used as feed, it is a component of the bones and teeth of livestock and is required for normal bone development. It is also an activator of various enzymes and plays an important role in sugar and protein metabolism. Feed grade magnesium sulfate is used as a supplement for magnesium in feed processing. Magnesium is an indispensable factor involved in the osteogenic process and muscle contraction in livestock and poultry, and is an activator of various enzymes in the body. It plays an extremely important role in material metabolism and neural function in livestock and poultry. If the body of livestock and poultry lacks magnesium, it can lead to material metabolism and neurological dysfunction, supply imbalance, affect the growth and development of livestock and poultry, and even lead to death.

4. It can also be used as fertilizer or compound fertilizer, and is also a raw material for producing magnesium oxide. Because magnesium is one of the main components of chlorophyll. Usually used for potted plants or magnesium deficient crops, such as tomatoes, potatoes, roses, chili peppers, and hemp.

5. Magnesium sulfate is used in the food industry for lactic acid, monosodium glutamate, etc.

6. Used as a filler in the leather industry.

7. Used as a conductive salt in the electroplating industry.

8. Used in the chemical industry to manufacture other magnesium salts such as magnesium stearate, magnesium hydrogen phosphate, magnesium oxide, and other sulfates such as potassium sulfate and sodium sulfate; Raw materials for manufacturing zinc barium powder and other zinc salts; Used as a filler in fire-resistant materials to enhance heat resistance. It is also an important auxiliary material for viscose fibers and vinylon fibers, and is also used as a wood and leather agent, a bone glue clarifying and protecting agent, and for electroplating and flotation minerals.
