Magnesium chloride is one of the substances that are abundant in brine and have high added value. In addition to its own use, other magnesium products produced from magnesium chloride are also very widely used. High purity magnesium oxide is one of them. At present, there are many methods to produce high purity magnesium oxide, magnesium chloride pyrolysis is one of the most popular methods in recent years, especially it does not need any additives, low production cost, no pollution to the environment, simple process and other advantages to become the best choice for many enterprises trying to put into large-scale production.
Hebei Messi Biology Co., Ltd. has prepared high quality magnesium chloride hexahydrate crystals by using Qinghai Salt Lake. Magnesium chloride pyrolysis was used to prepare magnesium oxide products with high purity and stable properties. The process parameters for the preparation of high purity magnesium oxide were explored in three main parts. The effects of pyrolysis time and pyrolysis temperature on the purity and activity of magnesium oxide and the decomposition rate of magnesium chloride were investigated in the magnesium chloride pyrolysis stage, and the relationship between magnesium oxide activity and its microstructure was explored. The study showed that with the increase of magnesium chloride pyrolysis temperature and time, the magnesium oxide purity and magnesium chloride decomposition rate kept increasing, the magnesium oxide activity kept decreasing, and the grain size kept increasing.
By investigating the reaction mechanism and kinetic parameters of magnesium chloride pyrolysis, Hebei Messi Biology Co., Ltd. provides the theoretical basis for the production of high-purity magnesium oxide by magnesium chloride pyrolysis. The optimized conditions of...
