I. Overview
High purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperature, with good light transmission, often can be used as high temperature heat resistant materials. In ceramic field, it is used as raw material of light transmitting ceramic crucible, substrate, etc. In the electrical field, it is used as filler for magnetic devices, insulating material, and various carriers. It is also used as raw material of high purity electrofused magnesium sand, which can be used as \”analytically pure\” magnesium oxide in chemical industry.
Generally high purity magnesium oxide refers to the product with magnesium oxide content more than 98%, so that magnesium oxide has good alkali resistance and electrical insulation at high temperature, and good light transmittance, high thermal conductivity, large coefficient of thermal expansion. Among them, ultra-fine high-purity magnesium oxide has become the focus of industry development. Ultra-fine magnesium oxide is the high-end magnesium oxide which has been gradually developed in recent years. High purity magnesium oxide generally refers to the magnesium oxide with content higher than 98%, mainly used in high-end fields and other industries, such as medicine, food, silicon steel, analytical purity and other industries. High purity magnesium oxide is classified according to the usage, including electrofused magnesium oxide, silicon steel magnesium oxide, electromagnetic magnesium oxide, pharmaceutical magnesium oxide and single crystal magnesium oxide, etc.

Third, the development status
With the development of industry, the application scale of high purity magnesium oxide in the traditional field is expanding day by day, new application fields are also being explored and developed, the market capacity is expanding, from the development trend, the proportion of high purity magnesium oxide consumption is increasing year by year, in 2020 China\’s high purity magnesium oxide production reached 63266 tons, the demand reached 84184 tons, it is expected that in 2022 China\’s high purity magnesium oxide production will reach 76124 tons, the demand will reach 99094 tons.

High purity magnesium oxide has excellent acid and alkali resistance and electrical insulation, good light transmission, high thermal conductivity, large coefficient of thermal expansion, widely used as high temperature heat-resistant materials, in the ceramic industry as ceramic cyan pot, substrate and other raw materials; in the electronics, electrical industry used as magnetic device filler, insulating materials and various carriers. more than 99% high purity magnesium oxide is the best chemical raw material for the production of oriented silicon steel sheet in the world today. In addition, with high-purity magnesium oxide as raw material, can also produce electrofusion magnesium oxide single crystal, high-purity electrofusion magnesium oxide, nanoscale magnesium oxide and other special magnesium oxide series products, these products in electronics, electrical appliances, optics, instrumentation, metallurgy, national defense and aerospace and other fields have a wide range of applications, according to statistics in 2014 China\’s high-purity magnesium oxide market size of 1.084 billion yuan, in 2020 China\’s high-purity magnesium oxide Magnesium oxide market size is 1.401 billion yuan, it is expected that in 2022 China\’s high-purity magnesium oxide market size will reach 1.584 billion yuan.
2014-2022 China high purity magnesium oxide market size statistics and forecast
With the maturity of production technology, the number of enterprises in the industry, production capacity production continues to increase, the supply is more adequate, the domestic market competition gradually intensified, the average price of high-purity magnesium oxide in China also showed a significant decline, the decline in 2018 is more obvious, about 16637 yuan / ton in 2020, at present, the price of high-purity magnesium oxide products in China is still relatively high, the production technology is insufficient, in addition to Hebei magnesium Xie biological Ltd. and other large manufacturers, the average size of other enterprises is smaller than the leading foreign enterprises, the future still has a lot of room for improvement, it is expected that the future of China\’s high-purity magnesium oxide production capacity production will continue to grow, driving the industry product prices continue to decline. But the change of industry demand structure, ultra-high purity magnesium oxide market demand accounted for an increase in the average price of industry products will be driven up.
