my country’s magnesium oxide types are increasingly abundant and production has increased

Magnesium oxide, also known as magnesia, is an alkaline oxide with the chemical formula MgO. It appears as a non-toxic, odorless white or off-white powder at normal temperature and pressure, and is soluble in acid and ammonium salt solutions. After combining with water, it can be converted into magnesium hydroxide under certain conditions. After years of development, the types of magnesium oxide have become increasingly abundant, which can be roughly divided into light burned magnesium oxide, activated magnesium oxide, high-purity magnesium oxide, etc. Among them, light-burned magnesium oxide is the mainstream product in the industry, accounting for 95.89% of the market.

At present, the preparation process of magnesium oxide is becoming increasingly mature, which can be roughly divided into carbonization method, calcination method, carbonation method, sintering method, brine ammonium bicarbonate method, hydrochloric acid method, gas phase method, etc. Among them, the carbonization method has become the mainstream production method in the industry due to its advantages of green environmental protection and low production cost.

From the upstream of the industrial chain, magnesite has become the main raw material for the production of magnesium oxide. Our country is very rich in magnesite resources. It not only has huge reserves and high quality, but also has a complete range of types. At present, my country’s total proven magnesite reserves are approximately 3.6 billion tons, accounting for 29.00% of the world’s total reserves. With the continuous mining of magnesite in my country, the output of magnesite has gradually increased, providing sufficient raw materials for the rapid development of the magnesium oxide industry.

Magnesium oxide has the advantages of high stability, easy synthesis, low production cost, etc., and has a wide range of applications. In the chemical industry, magnesium oxide can be used as a catalyst and desulfurizer, playing a very important role in chemical reactions. And magnesium oxide is mostly used in the production of refractory materials, waterproof building materials, etc. due to its good waterproof and fire resistance. In addition, magnesium oxide can also be used directly as an insulating material and thermal conductive material to produce different types of electronic products. Overall, my country’s magnesium oxide market demand is relatively large.

According to the “2023-2027 China Magnesium Oxide Product Market Analysis Feasibility Research Report” released by the Industrial Research Center, in this context Under the current situation, the production scale of my country’s magnesium oxide enterprises has gradually expanded, and output has increased. In 2022, my country’s magnesium oxide production will be 20.351 million tons, a year-on-year increase of 4.79%.

As one of the major producers of magnesium oxide, my country’s export volume is far greater than its import volume. However, affected by the epidemic, my country’s magnesium oxide exports have gradually declined. According to data released by the General Administration of Customs, in 2022, my country’s magnesium export volume will be 475,000 tons, a year-on-year decrease of 1.66%.

Industry analysts said that there are a large number of companies in my country’s magnesium oxide market, but most of them are small in scale and their production technology is not as advanced as internationally. There is a certain gap between levels. In recent years, my country’s magnesium oxide enterprises have continued to develop, production technology has gradually improved, and product types have become increasingly rich. At present, my country’s largest magnesium oxide companies mainly include Guanxu Chemical, Wancheng Magnesium, Linghang Chemical, Jiachen Group, Meisheng Chemical, Hengtian Group, etc.
