commonly Light burned magnesium ball It refers to products containing more than 98% of magnesium oxide, so that magnesium oxide has good alkali resistance and electrical insulation at high temperature, good light permeability, high thermal conductivity and large thermal expansion coefficient. Therefore, it is widely used in electronics, optics, instrumentation, metallurgy, national defense, aerospace and other fields. At present, China's demand for high-purity magnesium oxide is more than 100000 tons, while China can only produce about 10000 tons of high-purity magnesium oxide every year. The gap mainly depends on imported products to supplement, which has to be said to be a very regrettable thing to desulfurize magnesium oxide.
Ultra fine high-purity magnesium oxide has become the focus of industry development. Ultrafine magnesium oxide is a high-end magnesium oxide developed gradually in recent years. High purity magnesium oxide generally refers to the magnesium oxide with the content higher than 99.9%, which is mainly used in high-end industries, such as medicine, food, silicon steel, analytical pure, petroleum, analytical pure and other industries.
Ultrafine magnesium oxide has the characteristics of small particle size, large specific surface area, high chemical purity and good filling ability. With its superior performance, it has been widely used in many fields such as rubber, engineering plastics, medicine, daily chemicals, etc., and has provided a new process basis and technical guarantee for the development of its related chemical fields, enjoying the reputation of "industrial monosodium glutamate".
The production process of magnesium oxide has been further developed. With the continuous development of the downstream high-end application market, the requirements for the quality and stability of magnesium oxide have been constantly improved. At present, the magnesium oxide technology in China can not meet the application needs well, and high purity will become one of the most important development directions of magnesium oxide processing technology.
High purity magnesium oxide and ultra-fine magnesium oxide will become the development focus of the magnesium salt industry in the 21st century. The demand will grow rapidly and have a good market prospect. Some developed countries will realize it as a development direction. The demand for ultra-fine high-purity magnesium oxide in the world has also developed rapidly with the development of the industry.
