The problems and development direction of magnesium oxide production methods

As a magnesium containing by-product in industry, its impurity content and pre-treatment process have greater advantages compared to preparing magnesium based products from liquid ore.

        As a magnesium containing by-product in industry, its impurity content and pre-treatment process have greater advantages compared to preparing magnesium based products from liquid ore. Therefore, using magnesium containing by-products to prepare high-purity magnesium based products has become an important and effective way to enhance the taste of magnesium based products worldwide. Xinjiang has the Lop Nur Salt Lake and numerous other salt lake resources, with magnesium resources mainly composed of hydrated magnesium chloride reaching billions of tons. The production of magnesium products from salt lake waste is a very weak link in China's salt lake chemical industry. Due to various reasons, the development and utilization of salt lake resources are still limited to a single utilization of potassium chloride resources.

        In the process of preparing high-purity magnesium oxide from basic magnesium carbonate, the number of washes and filters is directly related to the yield of magnesium oxide; During the process of basic magnesium carbonate entering the muffle furnace, if the basic magnesium carbonate is too humid, it will have a negative impact on the furnace and reduce its lifespan. Therefore, drying should be carried out before this, and the degree of drying will affect the preparation in the later stage; When calcining, the calcination temperature is difficult to control because if the calcination temperature is too high, it is easy to burn the product to death. If the calcination temperature is too low, besides a long calcination time, the content of lightweight magnesium oxide cannot be guaranteed, so the temperature is difficult to control; In purity analysis, the removal of impurity ions cannot be fully guaranteed, so it is necessary to verify step by step during the process and strive to achieve the best results. High purity magnesium oxide has excellent acid alkali resistance and electrical insulation at high temperatures, good light transmittance, high thermal conductivity, and large coefficient of thermal expansion. It is widely used as a high-temperature heat-resistant material and as a raw material for ceramic crucibles, substrates, and other materials in the ceramic industry. Used as magnetic device filler, insulation material, and various carriers in the electronics and electrical industry.
         In addition, high-purity magnesium oxide can be used as raw material to produce specialized magnesium oxide series products such as fused magnesium oxide single crystals, high-purity fused magnesium oxide, and nanoscale magnesium oxide. These products are widely used in fields such as electronics, electrical appliances, optics, instruments, metallurgy, and national defense. With the rapid development of the Chinese economy, the scale of China's adhesive and sealing material industry has rapidly expanded, and it has entered the world's largest producer and consumer of adhesives and sealants. It can fully utilize existing resources, with low cost, solve environmental pollution, lay the foundation for the effective utilization of magnesium resources, and generate huge economic benefits.
