Magnesium sulfate heptahydrate (molecular formula MgSO4.7H20), also known as sulfur bitter, bitter salt, epsom salt, epsom salt, is white or colorless needle-shaped or oblique columnar crystals, odorless, cool and slightly bitter, molecular weight: 246.47, The specific gravity is 1.68, easily soluble in water, slightly soluble in ethanol or glycerin, soluble in its own crystal water at 67.5 ℃. Thermal decomposition, 70/80 ℃ is to lose four molecules of crystal water. About 200 ℃ lost all crystal water into anhydrous. It is easily weathered into powder in the air (dry), and gradually loses crystal water when heated, and becomes anhydrous magnesium sulfate. This product does not contain any toxic substances. Soda magnesium sulfate is easier to weigh than anhydrous magnesium sulfate because it is not easy to decompose, which is convenient for quantitative control in industry.

1.Agricultural application: Magnesium is the core element of chlorophyll, which can strengthen the plant reduction process, improve resistance, promote the activation of enzymes, make the compacted soil loose and strong, promote the development of roots, fully absorb nutrients, and make plants more lush. Sulfur is the composition of plants The main components of protein and enzymes in the body can promote root growth, enhance metabolism and redox in plants, thereby promoting vigorous growth of crops and increasing yield. Therefore, magnesium sulfate is an ideal raw material for making compound fertilizers. It can be mixed with nitrogen, phosphorus and potassium to form compound fertilizers or mixed fertilizers according to different needs, and can also be mixed with one or more raw materials to form various fertilizers and photosynthetic fertilizers. In the actual field comparative experiment of nine kinds of crops such as rubber tree, fruit tree, tobacco leaf, tea, vegetable, potato, etc., the compound fertilizer containing magnesium can increase the growth of crops by 15-20% compared with the compound fertilizer without magnesium.
2 Industrial application: The raw materials used to manufacture zinc-barium powder and other zinc salts are also important auxiliary materials for viscose fiber and vinylon fiber, and are also used as wood and leather agents, bone glue clarification and protection agents, and electroplating flotation, etc. .
3.Food application: Magnesium sulfate can be used as lactic acid monosodium glutamate in the food industry.
4 Feed application: Magnesium sulfate is a major additive in feed.
5 Application in printing and dyeing: In printing and dyeing, magnesium sulfate can be used as a weighting agent and a mordant for fabric dyeing.
6. Industrial sewage treatment: industrial production produces a lot of sewage, and magnesium sulfate can coagulate and settle waste liquid sewage.
