The application fields of high-purity magnesium oxide continue to expand, and the industry has broad room for development

Magnesium oxide is an ionic compound with the chemical formula MgO. It is an oxide of magnesium. It appears as a white loose powder. It is odorless, tasteless and non-toxic. It is difficult to dissolve in pure water and organic solvents, and is soluble in acids and ammonium salt solutions. High-purity magnesium oxide refers to magnesium oxide products with a magnesium oxide content of 98.5% and above. Currently, its main production method is the magnesium hydroxide method. The main production process is to use brine as raw material, ammonia/alkali as precipitant, and mix to prepare Magnesium hydroxide is then calcined and decomposed to produce high-purity magnesium oxide.

High-purity magnesium oxide has the characteristics of excellent alkali resistance, good electrical insulation properties, high thermal conductivity, good light transmittance, and high thermal expansion coefficient in high-temperature environments. It is mainly used as a high-temperature heat-resistant material or insulating material and is widely used in medicine, food, and electronics. , glass, silicon steel, chemical industry, ceramics, electrical and other fields. In recent years, against the background of the rapid development of its application fields, my country’s high-purity magnesium oxide market demand has continued to increase and its scale has continued to expand. According to the “China High Purity Magnesia Industry Application Market Demand and Development Opportunities Research Report 2022-2026” released by the Industrial Research Center , the domestic high-purity magnesium oxide market demand in 2021 will be 94,000 tons, a year-on-year increase of 9.8%; the market size will be 1.55 billion yuan, a year-on-year increase of 8.1%.

my country is the world’s major producer of magnesium compounds, and its domestic magnesite reserves rank first in the world. There is an adequate supply of raw materials such as brucite, serpentine, salt pan, bitter brine, and high-quality dolomite, providing a solid foundation for the industrial production of high-purity magnesium oxide. Excellent condition. At the same time, high-purity magnesium oxide continues to expand its application fields with its unique characteristics, and market demand continues to increase, which in turn stimulates the continuous improvement of domestic high-purity magnesium oxide production technology and the continuous development of the industry. Against the background of sufficient supply of raw materials and continuous improvement in demand-stimulated technology, domestic production of high-purity magnesium oxide continues to increase. In 2021, my country’s high-purity magnesium production will be 71,000 tons, a year-on-year increase of 12.3%.

At present, the market demand for high-purity magnesium oxide in my country is relatively large, but the production capacity cannot fully meet the growing market demand, and the supply and demand pattern presents an imbalance between supply and demand. In the future, local companies will need to continue to improve their technical level and expand production capacity, thereby promoting the continuous increase in domestic high-purity magnesium oxide production and the balance between supply and demand. There is still huge room for development in the domestic high-purity magnesium oxide market in the future. It is expected that its market size will be close to 3 billion yuan by 2023, and the industry has huge development potential.

From the perspective of market segments, silicon steel is currently the largest application field of high-purity magnesium oxide, accounting for 46%; followed by the food and electronic fields, accounting for 6% and 5% respectively. From the perspective of silicon steel field, domestic silicon steel grade high-purity magnesium oxide companies currently mainly include Industrial Zhentai Chemical, Zhentai New Materials, and Tongda Magnesium Salt. In recent years, under the background of the continuous improvement of the production technology of local high-purity magnesium oxide companies, domestic The process of market localization continues to accelerate, and in 2021, the three companies will account for more than 50% of the silicon steel grade high-purity magnesium oxide market share. Industrial Analysis personnel said that in the future, under the background of the continuous expansion of domestic high-purity magnesium oxide application fields and the continuous improvement of related technologies, its industry development The potential is huge.
