About magnesium sulfate, we are generally based on the number of water molecules combined with magnesium sulfate to distinguish, magnesium sulfate is generally divided into magnesium sulfate heptahydrate, magnesium sulfate monohydrate, anhydrous magnesium sulfate, etc., one of the crystal water is magnesium sulfate monohydrate, 7 is magnesium sulfate heptahydrate.

One, in the appearance of the difference between magnesium sulfate monohydrate and magnesium sulfate heptahydrate that is the difference in appearance, magnesium sulfate monohydrate is a white powder solid, but magnesium sulfate heptahydrate is colorless and transparent crystal.One is a powdered solid and the other is a clear, colorless crystal.Secondly, from the point of view of chemical structure, magnesium sulfate monohydrate is magnesium sulfate hydrate containing 1 water of crystal, the corresponding molecular weight is 138, magnesium sulfate heptahydrate water of crystal is 7, the corresponding molecular weight is 246.Therefore, the similar quality of magnesium sulfate monohydrate and magnesium sulfate heptahydrate, which about the percentagMagnesium sulfate heptahydrate is generally used in agriculture as fertilizer, providing magnesium elements, but also to feed additives.Magnesium sulfate heptahydrate is also often used in light industry in the production of fresh yeast, monosodium glutamate, beverages, mineral water; In the chemical industry for the manufacture of magnesium stearate, magnesium hydrogen phosphate, magnesium oxide... And sewage treatment;It IS used AS a filler in fireproof materials to enhance heat resistance, and in medicine for making laxatives, anticonvulsants, lactic acid in food industry, conductive salt in electroplating industry, dyeing agent on fabrics, aggravating agent, magnesium dyeing agent and so on.

Two, in the production process, magnesium sulfate heptahydrate is a kind of crystal, its appearance is different due to the production process.If the drying process is used, the surface of magnesium sulfate heptahydrate produces more water, crystalline, which is easier to hygroscopic agglomerate, and will absorb more free water and other impurities;If the process of drying treatment is used, the surface water of magnesium sulfate heptahydrate is less, not easy to agglomerate, and the product fluency is better.
