Magnesium chloride hexahydrate, with the chemical formula MgCl₂·6H₂O and CAS number 7786-30-3, is a widely used compound in many industrial and agricultural applications.
Longorder offers this product in two physical forms: 46% powder and 46% flakes. Both are designed to deliver consistent performance and high purity, meeting rigorous quality standards for various uses.


De-Icing and Anti-Icing
One of the primary applications of magnesium chloride hexahydrate is in de-icing and anti-icing operations. When spread on roads and walkways during winter, its hygroscopic nature allows it to absorb moisture from the surrounding air. This lowers the freezing point of water and helps in melting ice efficiently, ensuring safer travel conditions. Its use in dust control is another significant benefit; when applied to unpaved roads or construction sites, it binds fine particles and prevents dust from becoming airborne, contributing to environmental and occupational safety.
Water Treatment
In the realm of water treatment, magnesium chloride hexahydrate plays a key role. It is employed in wastewater management processes where the removal of impurities is crucial. The compound helps in coagulation and flocculation processes, which lead to the separation of suspended solids and enhanced clarity of the treated water. Its efficacy in these processes has made it a staple in industrial wastewater management systems, ensuring compliance with environmental regulations.
Chemical Synthesis
Beyond environmental applications, magnesium chloride hexahydrate is also highly valued in chemical synthesis. It acts as a catalyst or co-catalyst in several organic reactions, aiding in the production of fine chemicals and intermediates. In particular, its reactivity and solubility in water make it ideal for reactions where controlled moisture levels are necessary. Researchers and industrial chemists often choose this compound for its predictable performance and ease of handling.
Longorder’s magnesium chloride hexahydrate products stand out due to their purity and physical consistency. The powder form is finely milled to ensure quick dissolution and uniform distribution when mixed into solutions. The flake form, on the other hand, offers a controlled release of magnesium chloride, making it especially useful in applications where gradual action is desired, such as in slow-release formulations for agricultural uses.
Agricultural Sector
The agricultural sector benefits greatly from magnesium chloride hexahydrate as well. It is used as a magnesium supplement for soils that are deficient in this essential nutrient. Magnesium plays a vital role in plant physiology, being a central element in chlorophyll and enzyme activation. By applying magnesium chloride hexahydrate, farmers can improve plant growth, enhance crop yields, and correct nutrient imbalances in soils. Its application is not limited to soil; foliar sprays incorporating magnesium chloride hexahydrate are also used to provide immediate magnesium nutrition to crops during critical growth periods.
Industrial Settings
In industrial settings, the compound is prized for its non-corrosive nature compared to other chloride salts. This makes it a safer alternative in situations where equipment longevity is a concern. Industries such as textiles, paper manufacturing, and even pharmaceuticals find magnesium chloride hexahydrate to be an effective additive due to its ability to moderate pH levels and improve process efficiencies.
Environmental sustainability is increasingly critical in today’s industrial processes. Magnesium chloride hexahydrate is recognized for its relatively low environmental impact. When used appropriately, it minimizes the need for more hazardous chemicals while still delivering high performance. This eco-friendly profile, combined with its effectiveness, has helped Longorder’s product gain acceptance in many markets where sustainability is a key purchasing criterion.
In summary, Longorder’s Magnesium Chloride Hexahydrate Powder and Flakes offer an excellent balance of quality, purity, and versatility. Whether for de-icing roads, managing dust, treating wastewater, aiding chemical synthesis, or enhancing agricultural productivity, this compound meets diverse needs across industries. Its robust performance and environmentally responsible profile make it a valuable ingredient in modern industrial and agricultural processes.
