Magnesium Chloride CAS 7786-30-3 Powder Granular Flake Prill

Magnesium Chloride is a widely used industrial chemical with multiple aliases, including magnesium dichloride, chloromagnesite, and magnesium(II) chloride. Its chemical formula is MgCl₂, which is a key identifier of this compound. The CAS number for magnesium chloride is 7786-30-3, a critical reference for global procurement and regulatory compliance.

Product Characteristics & Physical Properties

Magnesium Chloride exists in various common appearance forms, including powder, granular, flake, and prill, which can be selected according to different application scenarios and processing requirements.

Physically, it is a white or off-white substance with good solubility in water, and the aqueous solution is slightly acidic. It has a melting point of 714°C and a boiling point of 1412°C. It is hygroscopic, so it should be stored in a dry and well-ventilated environment to avoid moisture absorption and caking. This compound is odorless and non-toxic under normal use conditions, with stable chemical properties.

Common Product Specifications

Product Applications

Magnesium Chloride has a wide range of applications across multiple industries, making it a versatile product for global importers and purchasers.

In the construction industry, it is commonly used as a coagulant in the production of magnesium oxychloride cement, which is widely applied in building materials such as floor tiles, wall panels, and fireproof boards due to its high strength and good fire resistance.

In the deicing and snow-melting field, magnesium chloride is an environmentally friendly deicer that can lower the freezing point of water effectively, preventing ice formation on roads, airports, and sidewalks without causing significant damage to the environment or infrastructure.

In the chemical industry, it serves as an important raw material for the production of magnesium metal, magnesium hydroxide, and other magnesium compounds. It is also used as a catalyst and additive in various chemical reactions.

Additionally, it is used in the food industry as a food additive (E511) for texture improvement and preservation, in the agricultural industry as a magnesium fertilizer to supplement essential nutrients for crops, and in the pharmaceutical industry for certain medicinal preparations.

Regulatory Compliance & Safety

Magnesium Chloride has completed REACH registration, complying with the European Union's regulatory requirements for chemicals, which is a key guarantee for its circulation and use in the European market. For safety information and handling guidelines, MSDS download is available to provide detailed data on hazards, first-aid measures, storage, and transportation.

FAQ

Q1: What is the shelf life of magnesium chloride in different appearance forms?
A1: Under proper storage conditions (dry, ventilated, away from moisture and high temperature), the shelf life of magnesium chloride powder, granular, flake, and prill forms is usually 24 months from the date of production.

Q2: Is magnesium chloride compatible with other common industrial chemicals?
A2: Magnesium chloride is compatible with most inorganic salts and acids (except strong oxidizing acids). It is not compatible with strong bases, as it will react to form magnesium hydroxide precipitation. It is recommended to conduct compatibility tests before mixing with other chemicals.

Q3: What packaging options are available for magnesium chloride for international transportation?
A3: For international transportation, magnesium chloride is usually packaged in 25kg woven bags with inner plastic liners, 500kg jumbo bags, or 1000kg jumbo bags, which can effectively prevent moisture absorption and ensure the stability of the product during transportation. Customized packaging can be provided according to specific order requirements.
