What is Magnesium Chloride?

Chemical formula MgCl2. The most common one is magnesium chloride hexahydrate, also known as bischofite, its chemical formula is MgCl2·6H2O, and the formula weight is 203.30. The crystals are colorless and deliquescent monoclinic crystals with a bitter and salty taste. The density is 1.569g/cm3, the melting point is 118°C (decomposition), and it is easily soluble in water and ethanol. Above 170°C, basic magnesium chloride and hydrogen chloride are formed. Decomposes at 600°C to generate magnesium oxide and hydrogen chloride.

Anhydrous magnesium chloride is a white shiny hexagonal crystal, which is easily deliquescent. Odorless. There is a bitter taste. The relative molecular mass is 95.22. Density 2.32g/cm3, melting point 714°C, boiling point 1412°C, slightly soluble in acetone, soluble in water, ethanol, methanol, and pyridine. It deliquesces and emits smoke in humid air, and sublimates when it is white hot in a stream of hydrogen. It is easily dissolved in water and emits heat violently.

Green Agri is a manufacturer of calcium chloride, magnesium chloride and refined 46% magnesium chloride brine tablets for agriculture and fishery. The product quality is stable and magnesium chloride is widely used in aquaculture water quality adjustment, calcium supplementation for shrimps and crabs, magnesium supplementation for algae, etc.

Add 50-90 grams of magnesium oxide or 0.5% of the concentrate amount to dairy cow food every day, which can not only supplement the magnesium in the diet

The deficiency prevents the occurrence of magnesium deficiency, and is an excellent rumen buffer, regulates rumen sourness, and can

Increase the absorption of the precursors of milk synthesis by the mammary glands, increase milk production and milk fat rate.


Newborn chicks can only survive for a few days when fed diets that are completely deficient in magnesium. When fed a low-magnesium diet, the chicks grow

Slowness, lethargy, wheezing, shortness of breath, short-term convulsions after being frightened, and finally leading to temporary coma or death.


Due to the continuous improvement of pig breeds and the continuous improvement of productivity, the nutritional needs of magnesium should be correspondingly improved.

Freshwater fish

Freshwater fish have insufficient amounts of dissolved magnesium in the water, so they need to be properly supplemented with magnesium in their feed.
