White hexagonal crystalline powder, odorless, highly hygroscopic, and chemically stable. Exothermic when dissolved in water, forming a weakly acidic solution. Non-flammable and non-explosive, it is a key inorganic magnesium salt raw material.

1. Building Materials Industry:Core raw material for magnesia cement, used in the production of fireproof boards, partition boards and ventilation ducts, improving the strength and water resistance of products.
2. Metallurgical Industry:Anhydrous magnesium chloride serves as a raw material for electrolytic magnesium production, and is also used in magnesium alloy smelting and electroplating solution preparation.
3. Food Industry:Food-grade product is used as a coagulant for soybean products (tofu, dried tofu) to achieve a tender and smooth texture. It can also be used as a dairy stabilizer and mineral supplement (in compliance with GB 25584-2010).
4. Industrial Auxiliaries:Road snow-melting agent (compounded with calcium chloride), textile anti-wrinkle agent, catalyst support for organic synthesis, and antifreeze.
5. Pharmaceutical Field:Used in the production of magnesium preparations, preparation of hemodialysis solution, and prevention and treatment of hypomagnesemia.
6. Agriculture / Feed:Feed-grade product is used to supplement magnesium for animals, and as a water quality regulator in aquaculture.
