Magnesium oxide is an important inorganic chemical product. As a filler, it is widely used in rubber, plastics, toothpaste, food, medicine and other industries. Its raw materials are mainly derived from natural magnesite, dolomite and so on. After the magnesium oxide and magnesium oxide are activated, the active magnesium oxide is obtained, and the application performance is greatly improved.
The production of ultrafine (active) magnesium oxide with different crystal forms and ultra-fine ultra-white, high-purity, surface-modified magnesium oxide has become the main direction of the magnesium oxide industry. The application and development of magnesium oxide deep processing products has become a top priority. Generally, the consumption demand of magnesium oxide in developed countries is 14 to 18 times that of magnesium oxide.
China’s research and development of magnesium oxide and magnesium oxide deep processing products have gradually received attention since the 1980s. However, due to the late start, there are still problems of single variety, low grade, small output, and unreasonable consumption structure, forming high-purity magnesium oxide with low-end magnesium oxide supply exceeding demand and high added value and rapid market demand. Active magnesium oxide is heavily dependent on the embarrassing situation of imports.
The existing magnesium oxide product structure in China has been unable to adapt to the changes in market demand. Ordinary magnesia should not be used as a new device. It should focus on the development of high-purity active magnesium oxide with excellent performance, and gradually introduce magnesium oxide by introducing advanced foreign technology and equipment. The development focus of the industry has gradually shifted from magnesium oxide to magnesium oxide to meet the needs of the domestic market and further enhance international competitiveness.
