Magnesium oxide (MgO) is a versatile chemical compound that plays a vital role in various industries due to its unique properties. It is a white, odorless powder that is produced by heating magnesium carbonate or magnesium hydroxide to high temperatures, causing it to decompose into magnesium oxide and carbon dioxide.

​Brucite is a naturally occurring mineral composed primarily of magnesium hydroxide (Mg(OH)₂), and it is commonly found in metamorphic rocks. While it shares some similarities with asbestos minerals, such as its fibrous structure, it is not classified as an asbestos mineral.

Magnesium oxide (MgO), also known as magnesia, is a highly versatile compound widely used in various industries due to its unique properties. Its primary applications span fields such as healthcare, agriculture, construction, and manufacturing.

Flame retardant are critical components used in a wide range of applications to enhance the fire resistance of materials, particularly in the plastics and resin industries. Among the various flame retardants, magnesium hydroxide (Mg(OH)₂) and aluminum hydroxide (Al(OH)₃) are two commonly used inorganic compounds.

One of the primary industrial uses of brucite is as a flame retardant. When heated, brucite decomposes into magnesium oxide and water vapor, both of which help to suppress flames. This property makes brucite a valuable additive in fire-resistant materials, including coatings, plastics, and textiles. It is widely used in industries such as construction, automotive, and electronics to improve fire safety.

The surface modification of magnesium hydroxide is to improve its compatibility and dispersion in the polymer base material, thereby improving the mechanical properties and flame retardant efficiency, while reducing environmental pollution and optimizing the overall performance of the product. Here are seven main reasons why surface modification of magnesium hydroxide should not be ignored:

In recent years, fire accidents caused by polymers have attracted great attention from all walks of life, and the research and development of flame-retardant polymers has become a hot topic. At present, organic flame retardants used in the market have hazards such as large smoke production and toxic smoke, which are subject to legal restrictions in Europe, the United States, Japan and my country. Therefore, inorganic flame retardants have received great attention.

Magnesium hydroxide (Mg(OH)₂) is a white crystal or powder with weak alkalinity and hygroscopicity. The part soluble in water is completely ionized, and the saturated solution concentration is 1.9 mg/L (18°C). Its preparation methods include brucite grinding method and chemical synthesis method (such as calcium hydroxide method, ammonia method, sodium hydroxide method).
