Specialization and functionalization are the future development trend of magnesium oxide. Mainly used in high-grade aerospace, medicine, food and other fields. Source control is very important in the production of magnesium oxide, playing a good role in subsequent production. Carbonization is a commonly used production method for magnesium oxide. The raw material is high quality magnesia ore. Among them, the MgO content is required to be large, otherwise the hydrochloric acid insoluble matter content, the whiteness and other specifications are difficult to meet the requirements.

In some places, the ore content of MgO is not up to standard, and the content of impurities such as silicon, calcium and iron are high. The whiteness and impurity content of the products obtained by the conventional production process are not up to the requirements. At this time, it is necessary to take some measures from the source to optimize the magnesium oxide production process.

At present, China’s ordinary magnesium oxide products are single, the special function of magnesium oxide is lacking, the technical content is low, the production process is backward, and there is still a certain gap with foreign countries. China’s magnesium oxide enterprises should be strengthened from the following aspects:

(1)Rational and efficient use of resources, relying on advanced science and technology to improve unit productivity;

(2)Enterprises should have reasonable scale and series and products, improve the quality of magnesium oxide products, and take the road of refinement, specialization, functionalization and serialization.

(3)Should pay attention to the needs of the downstream market, actively develop new products to meet the individual needs of downstream users
