Product Description:

Magnesium chloride is an inorganic ionic compound with the chemical formula MgCl₂ (anhydrous) / MgCl₂·6H₂O (hexahydrate), appearing as white crystalline powder, flake, granule or colorless transparent liquid, with slight hygroscopy and easy solubility in water and ethanol (dissolution is slightly endothermic). Classified into industrial grade and food grade according to application standards, with controllable main content and low impurity content, it features stable chemical properties and easy storage and transportation (sealed against moisture). The product has diverse specifications and customizable concentrations, widely used in chemical industry, construction, food processing, aquaculture and other fields, and is a versatile basic chemical raw material with excellent performance and high cost-effectiveness.
