[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods of magnesium silicate, how to write magnesium silicate

Magnesium silicate properties

Magnesium silicate (Magnesium Silicate) is an inorganic compound, mainly composed of magnesium, silicon and oxygen, the chemical formula is usually expressed as MgSiO3 or Mg2Si3O8. It is white powder, insoluble in water, with good thermal stability and chemical inertness. Magnesium silicate has a density of about 2.9g/cm³ and a high melting point, usually above 1200°C, which makes it superior in high temperature applications. Magnesium silicate has good adsorption, can absorb water, grease and other substances, is a commonly used adsorbent.

Magnesium silicate uses

The wide use of magnesium silicate is due to its unique physical and chemical properties. In industry, magnesium silicate is commonly used as a filler and reinforcing agent, and is widely used in rubber, plastics, coatings and paper industries. Its good adsorption properties make it an effective adsorbent and catalyst carrier for environmental protection and chemical synthesis. Magnesium silicate is also used in the production of fireproof materials and high-temperature resistant materials, thanks to its high melting point and thermal stability. In the pharmaceutical and cosmetic industries, magnesium silicate is widely used as an ingredient in antacids and talc, with good safety and biocompatibility.

Magnesium silicate upstream feedstock

The main raw materials for the production of magnesium silicate are magnesium ore and silica (the main component is silicon dioxide, SiO2). The common magnesium ores are dolomite (CaMg(CO3)2) and magnesite (MgCO3). These ores can be calcined and chemically treated to obtain magnesium oxide (MgO). Silica has a wide range of sources and can be obtained by collecting and processing natural quartz sand. Magnesium silicate can be synthesized by reacting magnesium oxide and silicon dioxide at a high temperature. In some processes, it may be necessary to use chemical raw materials such as magnesium chloride and sodium silicate for auxiliary treatment to improve product purity and reaction efficiency.

Magnesium Silicate Downstream Applications

As a functional material, magnesium silicate has a wide range of downstream applications. In the rubber and plastics industry, magnesium silicate is used as a reinforcing agent and filler to improve the mechanical strength and wear resistance of the product. In the coating industry, magnesium silicate as a filler can improve the weather resistance and corrosion resistance of coatings. In the field of environmental protection, magnesium silicate is widely used as an adsorbent in sewage treatment and air purification. In the field of medicine and cosmetics, magnesium silicate, as an excipient and filler for drugs and cosmetics, is widely used in antacid drugs, cosmetic foundations and other products, with good hygroscopicity and safety.

Magnesium silicate storage method

Due to the strong moisture absorption of magnesium silicate, special attention should be paid to moisture resistance during storage. Magnesium silicate should be stored in a dry, cool, well-ventilated warehouse to avoid contact with moisture. Storage containers should be well sealed to prevent moisture from the air from entering. Especially in high humidity environments, it is recommended to use packaging materials with moisture-proof functions, such as composite film bags or moisture-proof barrels. During transportation, pay attention to moisture-proof, try to avoid loading, unloading and transportation in rainy days, and take appropriate protective measures to ensure that the quality of magnesium silicate is not affected.

Magnesium Silicate Market Prospects

With the continuous development of industry and technology, the market demand for magnesium silicate is also growing. Especially under the promotion of the environmental protection industry, magnesium silicate, as an efficient adsorbent, has a very broad market prospect. With the increasing demand for high-performance fillers and reinforcing agents in traditional industries such as rubber, plastics and coatings, the application range of magnesium silicate will be further expanded. The increasing demand for high safety and high purity excipients in the pharmaceutical and cosmetic industries also provides a broad market space for magnesium silicate. It is expected that the market size of magnesium silicate will grow steadily in the future and become an important part of the functional materials market.

Conclusion

As a multifunctional inorganic material, magnesium silicate has a wide range of industrial applications and good market prospects. Its unique physical and chemical properties make it widely used in rubber, plastics, coatings, environmental protection, medicine and cosmetics. The upstream raw materials of magnesium silicate are mainly magnesium ore and silica, and high-purity magnesium silicate can be prepared by high-temperature synthesis process. During its storage, special attention should be paid to moisture-proof to ensure its quality and performance. With the continuous growth of market demand, magnesium silicate will continue to play an important role and become an important driving force for industrial and technological development.
