CAS NO.:7786-30-3
Molecular Formula::MgCl₂
Product Characteristics:
Magnesium chloride anhydrous is a white crystalline powder or hexagonal crystal, odorless, tasteless, and uniform in texture. It is easily soluble in water and also soluble in ethanol, with its solubility in water increasing as the temperature rises. The aqueous solution is weakly acidic and chemically reactive, with magnesium ions having strong coordination ability and being capable of reacting with various substances. It has extremely strong hygroscopicity, is prone to deliquescence in humid air, and thus needs to be sealed for storage. It exhibits excellent thermal stability at high temperatures, with a melting point of 714℃ and a boiling point of 1412℃.
