Magnesium Chloride Spherical is widely used in many fields due to its spherical structure, good fluidity and non-agglomeration characteristics. In the metallurgical industry, it is the core raw material for the electrolytic production of magnesium metal and is indispensable. High-purity magnesium metal can be extracted through high-temperature melting electrolysis; at the same time, it can also be used as a binder for refractory materials to enhance the high temperature resistance and structural strength of refractory bricks, furnace linings and other materials. In the chemical industry, spherical magnesium chloride is the basic raw material for the preparation of a variety of magnesium salts (such as magnesium oxide, magnesium hydroxide, magnesium carbonate), and is also an important intermediate for the production of other magnesium-containing compounds; In addition, as a component of antifreeze, it can effectively reduce the freezing point and is often used for road snow melting and chemical production of antifreeze. In the field of building materials, magnesium chloride and magnesium oxide can be mixed to make magnesium oxychloride cement, which is used to make fireproof boards, ventilation ducts, artificial marble, etc., with the characteristics of high strength and good fire resistance. In agriculture and animal husbandry, it can be added to feed to supplement the magnesium needed by animals and prevent magnesium deficiency; it can also be used as a soil conditioner to adjust the soil pH and improve the ability of crops to absorb nutrients. In the pharmaceutical industry, magnesium chloride can be used to make drugs such as antacids and laxatives, and can also be used as an injection ingredient to treat hypomagnesemia.

There are many wonderful methods for preparing Magnesium Chloride Spherical, all of which are based on physical and chemical principles. The first is the melt crystallization method: take anhydrous magnesium chloride and heat it to a molten state, control the temperature and slowly cool it down, so that it will self-condense into a sphere due to the effect of surface tension when it crystallizes, and then crush and screen it after cooling to obtain a sphere with uniform particle size. This is the so-called "hot melt bead" technology. The second is the spray drying method: use a high-pressure spray device to turn the magnesium chloride aqueous solution into fine droplets, and quickly dry it in a hot air flow. After the droplets are dehydrated, they self-condense into spherical particles due to the effect of surface tension. This method is efficient and fast, and the resulting spherical particles are crisp and porous. Third, the precipitation conversion method: react the magnesium chloride solution with an alkaline solution (such as ammonia water) to generate a magnesium hydroxide precipitate, which is recrystallized by hot liquid treatment, and then neutralized with hydrochloric acid and evaporated and crystallized.

Compared with other types of magnesium chloride (such as flakes and powders), Magnesium Chloride Spherical has many advantages in appearance, performance and application scenarios. First, Magnesium Chloride Spherical has better fluidity and more stable storage. The spherical structure reduces the friction between particles and is not easy to agglomerate. It can avoid agglomeration caused by moisture absorption during transportation and storage. It is especially suitable for automated feeding equipment to ensure accurate metering. Flake or powdered magnesium chloride is easily affected by moisture adhesion, which affects its use efficiency. Second, Magnesium Chloride Spherical dissolves quickly and has good uniformity. The contact area between spherical particles and water is more uniform, and it is not easy to form local overconcentration during dissolution. It can be quickly dispersed in the solvent. When preparing magnesium salt solutions or as reaction raw materials, the reaction rate and product purity can be improved. In contrast, powdered magnesium chloride is prone to dust when dissolved, and flake magnesium chloride dissolves slowly. Third, Magnesium Chloride Spherical has stronger adaptability in application scenarios. In areas with high requirements for fluidity (such as raw material pretreatment for magnesium smelting and automatic batching systems for refractory materials), spherical particles can reduce the risk of equipment blockage; in industries such as medicine and food that have high requirements for raw material form, the spherical structure is easy to control the amount of addition, has lower impurity content, and meets higher hygiene standards. In addition, the bulk density of Magnesium Chloride Spherical is more stable, which can reduce the storage space occupied. At the same time, its surface finish is high, which can reduce the difficulty of subsequent purification processes when preparing high-end magnesium compounds. In general, the morphological advantages of spherical magnesium chloride make it more competitive in high-end manufacturing, fine chemicals and other fields, while traditional forms of magnesium chloride are more suitable for basic industrial scenarios with low morphological requirements.

The quality standards of Magnesium Chloride Spherical mainly cover chemical composition, physical properties and other aspects. The core indicators include: the content of magnesium chloride (MgCl₂) must reach more than 95% (slightly different depending on the purpose) to ensure sufficient active ingredients; the moisture content is usually controlled at 1% - 3% to prevent moisture absorption and agglomeration from affecting performance; The particle size distribution requires uniform spherical particles, and the particle size is mostly in the range of 0.1 - 5mm to ensure fluidity; the impurity content is strictly limited, such as calcium, iron, and heavy metals (lead, arsenic, etc.) must comply with relevant industry standards (such as chemical grade, pharmaceutical grade), especially food or pharmaceutical use must meet higher safety requirements; the sphericity must be ≥90% to ensure that the particles are regular spherical and avoid irregular particles affecting the use effect. Different application fields (such as metallurgy, chemical industry, and medicine) will refine the standards according to specific needs, and verify compliance through particle size analysis, component testing and other means.

The market price of Magnesium Chloride Spherical varies greatly due to factors such as purity, process, and dosage. The general industrial grade content is about 46%, and the price per ton is between 600 yuan and 980 yuan. If the purity is higher, such as medical grade or purity exceeding 99%, the price will be much more expensive, between 7,600 yuan and 9,700 yuan per ton. This price change is closely related to the cost of raw materials and market supply and demand. For example, if the price of magnesium ore rises and the supply is tight, or the preparation process of the spherical structure is complicated and the cost is high, the price will naturally rise. On the contrary, if the market supply is sufficient and the merchants are in fierce competition, the price will remain stable. Therefore, if you want to know the exact price, you still need to judge it in combination with the current market conditions, the quality of the goods and the purchase volume.
