Fluorescent grade magnesium oxide has broad market application prospects and my country’s independent supply capacity will be improved

Fluorescent grade magnesium oxide appears as amorphous powder, odorless, tasteless, non-toxic, insoluble in water, insoluble in alcohol, and soluble in acid or ammonium salt solution. Under high temperature conditions, fluorescent grade magnesium oxide has excellent alkali resistance, electrical insulation, light transmittance, etc., and is mainly used as raw material for tri-primary color phosphors and other types of light bodies. It is widely used in electrical materials, electrical appliances, etc. , display and other fields.

Magnesium oxide is an alkaline oxide. With its high hardness, high insulation, high temperature oxidation resistance and other characteristics, magnesium oxide is widely used in analytical reagents, industry, aerospace, medicine, electronic information, metallurgy, ceramics and other fields. There are various methods for preparing magnesium oxide, including carbonization method, calcination method, hydrochloric acid method, brine ammonium bicarbonate method, double carbon reduction method, ammonium bicarbonate method, etc. my country is a major producer and exporter of magnesium oxide. In 2022, the output of my country’s magnesium oxide industry will reach more than 20.3 million tons.

In recent years, with the expansion of application fields and the rapid development of high-end technology, the types of magnesium oxide have gradually increased. According to different application fields, magnesium oxide can be divided into industrial grade, fluorescent grade, silicon steel grade, pharmaceutical grade, aerospace and military grade, etc. Among them, fluorescent grade magnesium oxide is used in fluorescent rods, PDP displays, LED phosphors, three-primary color phosphors and other fields. More. Based on abundant rare earth resources, the localization rate of my country’s rare earth luminescent materials continues to increase. Among them, the localization rate of white LED phosphors has now reached more than 85%. The main LED phosphor suppliers in my country include Youyan Rare Earth, Keheng Co., Ltd., Jiangsu Borui, and Xinli Light Source.

According to the “2023-2028 China Fluorescent Grade Magnesium Oxide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , the main raw materials of phosphors include zinc sulfide, magnesium sulfide, magnesium oxide, etc. Magnesium oxide is expected to become the main raw material of phosphors in the future. From this point of view, the market application prospects of fluorescent grade magnesium oxide are broad. For a long time, my country’s fluorescent grade magnesium oxide market has been dominated by foreign companies. Domestic related R&D or production companies include Magnesium Technology, Qinghai Mosheng New Materials, Hebei Shouzheng Nano Technology, etc.

In October 2023, Qinghai built a fluorescent grade magnesium oxide production line with an annual output of 500 tons. This production line is the first domestic carbonization method fluorescent grade magnesium oxide pilot production line. It uses magnesium hydroxide as raw material and uses carbonization method technology. It involves Impurity removal, sedimentation, filtration and other processes. This production line has filled the gap in domestic carbonization method for producing fluorescent grade magnesium oxide products, and has a good role in promoting the improvement of the magnesium products industry chain and the high-end development of the magnesium oxide industry.

Industry analysts said that my country is the world’s largest producer and exporter of raw magnesium. In 2022, my country’s raw magnesium exports will reach 50% More than 10,000 tons. my country is rich in magnesium resources and has raw material advantages in developing the fluorescent grade magnesium oxide industry. The fluorescent grade magnesium oxide market has broad development space, but for a long time, my country’s fluorescent grade magnesium oxide market has relied on imports. In the future, as relevant production lines are put into operation, my country’s independent supply capacity of fluorescent grade magnesium oxide will be further improved.
