High purity magnesium oxide includes high purity industrial magnesium oxide, high purity silicon steel magnesium oxide and high purity pharmaceutical magnesium oxide.
The project of preparation of high-purity Magnesium oxide and Porous Adsorbent from Serpentine was set up in February 1993. After hundreds of tests, a major breakthrough was made from the end of 1996 to the beginning of 1997, with over 98% of high-purity magnesium oxide and low-quality porous adsorbents obtained.
In June 2000, the first trial production was successful, more than 98% high-purity magnesium oxide was obtained, and more than 99% high-purity magnesium oxide and high quality porous adsorbent were obtained on December 3 of the same year.
The formal production of small batch production started in 2001, which ended the history that Chinese people could not produce high-purity magnesium oxide, and turned a new page in the production of magnesium salt in China.
High purity magnesium oxide due to different industries, each industry to its requirements of different indicators, such as the electronics industry in some components must be more than 99% of magnesium oxide.
In addition to the special requirements for physical parameters, chemical purity of silicon steel magnesium oxide also has special requirements. CaO and B2O3 reduce the refractoriness, so the lower the better, SO42-, C1- lower the better, the lower the total amount of impurities, the better.
The lower the toxic and harmful elements of PB, Hg, As and Cd, the better.
With the continuous improvement of science and technology and comprehensive national strength, constant innovation in science and technology is required to meet the needs of rapid development.
On the basis of research and production in recent years, the recovery rate and energy saving and consumption reduction of over 99% high purity magnesium oxide production with serpentine and brucite have been started in 2006, and great progress has been made in process improvement.
Using serpentine production more than 99% of high purity magnesium oxide are strong and porous adsorbent post invention technology, is the only Chinese people to industrialized production, with independent intellectual property rights of high-tech projects: after several years of production practice, the project has experienced from stage to the success of the laboratory model breakthrough, from industrial production to the improvement of the technology and mature, from the production cost is higher to the lower cost of saving energy and reducing consumption.
It has formed various kinds of solid (liquid) minerals containing magnesium to produce more than 99% high purity magnesium oxide products with different specifications and USES.
At present, there are still some difficulties in the Chinese market of high-purity magnesium oxide, which affects the development of the industry. With the improvement of China's comprehensive national strength, the development of high-purity magnesium oxide has great prospects.
