Apperance: Properties of Industrial magnesium sulfate generally refers to seven water. For colorless fine needle-like or oblique columnar crystals. Odorless and bitter. 

Nature: colorless tetragonal columnar crystals or granular crystals. The taste was salty and slightly bitter. d 1. 67. 47 degrees below the more stable. Dry air is susceptible to weathering, losing 1 crystal water. Lose 4 crystal water at 70~80 ℃. 100 deg C lost 5 crystal water, 120 deg C lost 6 crystal water, if exposed to humid air and rapid absorption of water. About 250 ℃. Became anhydrous. Soluble in water (20 degrees C: 7lg/lOOmL; 40 degrees C: 91g/lOOmL), the solution is neutral, pH 6~7. Slightly soluble in ethanol.

Use: magnesium sulfate is an important inorganic chemical products, the use is very extensive. In medicine, for the deployment of protective ointments, laxatives, analgesics, antidotes; In the microbial industry used as medium components, brewing additives, fermentation of nutrient sources, in the light industry for fresh yeast, monosodium glutamate, beverage, mineral water, health salt, sea crystal, Bath Kang, Borton beer and toothpaste in the production of calcium hydrogen phosphate stabilizer; In food additives for nutritional supplements, curing agents, flavor enhancer, processing aids; in the chemical industry for the manufacture of magnesium stearate, magnesium hydrogen phosphate, magnesium oxide and other magnesium salts and potassium sulfate, sodium sulfate and other sulfate; In the printing and dyeing industry as an alkali-resistant agent for printing and dyeing thin cotton, silk, also used as cotton, silk weighting agent, also do the filling of cotton products and for the production of rayon; In the manufacturing industry used as a filler to enhance heat resistance; In the electroplating industry to do conductive salt; in the feed additive, the main supplement of magnesium, is the composition of livestock bones and teeth, but also a variety of enzyme activators, play an important role in sugar and protein metabolism; Used as fertilizer in agriculture, it is a two-element fertilizer, sulfur/magnesium are the amount of nutrient elements, necessary for crop production. Magnesium is the sixth largest nutrient element of crops, is a component of chlorophyll and pigment, is the only metal element in the chlorophyll molecule, magnesium can promote photosynthesis, promoting the formation of carbohydrate protein/fat I is used as a flame retardant for plastics such as acrylate resin, epoxy resin, unsaturated polyester and polyurethane in the aspect of fire protection materials; In the environmental protection for industrial sewage treatment; In the paper industry also has applications, can also be applied to cement coagulant, explosives, powder, porcelain, glass, pigment, ABS resin manufacturing.
