On December 2, the "Technical Achievement Conference of the Ultra-High Purity Magnesium Oxide Project by the Galvanic Cell Method" was held in the TS Economic Development Zone. Hay Think learned from the press conference that the "Primary Cell Method Ultrasound" independently developed by BJTS High-purity magnesium oxide" technology achieved a breakthrough.
High-purity magnesia is a fine chemical product and high-temperature refractory material, which is widely used in various high-end fields such as aerospace electronics. China imports about 400,000 tons of high-purity seawater magnesia each year. Under the environment of comprehensive transformation and upgrading of steel enterprises, it is expected that China's entire The steel industry's annual demand for high-purity magnesia is 1.4-1.6 million tons. At present, the main production processes for preparing magnesium oxide at home and abroad are ore calcining and seawater/brine purification. The highest purity of magnesia by ore calcining is only 98.5%, which can no longer fully meet the needs of high-end manufacturing industries such as China's metallurgy; The European seawater synthesis law has been in a monopoly position for a long time, which has caused China to import a large amount of it and the cost remains high.
In this regard, after nearly 20 years of research and development of the "galvanic ultra-high-purity magnesium oxide" technology, BJTS has used carbon-based polymers as a breakthrough catalyst to produce ultra-high-purity magnesium oxide with the highest purity of 99.95%. According to reports, the galvanic cell method has lower preparation costs, shorter process routes, higher product yields, more stable processes, no (low) energy consumption in the production process, and can generate a large amount of high-quality direct current. It is a green, efficient, and A stable and low-cost preparation method of high-purity magnesium oxide.
BJTS`s ultra-high-purity magnesia project of galvanic cell method has officially entered the preliminary stage of industrialization. It is expected to achieve mass production of more than 1,000 tons in 2022; the production capacity of 200,000 to 300,000 tons in 2023-2025 will be used for the steel industry. The metallurgical industry, ceramic industry, high-temperature materials industry and other heavy industry fields provide basic materials necessary for transformation and upgrading.
