The size of the boehmite market continues to expand, and the lithium battery field is its largest demand end.

Boehmite, also known as boehmite and boehmite, has a molecular formula of γ-AlOOH and is the main component of bauxite. Boehmite appears as white crystals with glass or pearl luster. According to different purity, it can be divided into two types: high-purity boehmite (purity above 99%) and ordinary boehmite (purity below 99%). Boehmite has the characteristics of good chemical stability, large porosity, high temperature resistance, and good insulation. It is widely used in semiconductors, optical materials, ceramic materials, coatings, catalysts, lithium batteries and other fields.

Boehmite preparation methods include sol-gel method, direct aluminum hydrolysis method, hydrothermal synthesis method, aluminum alkoxide hydrolysis method, etc. The hydrothermal synthesis method is an emerging preparation method for boehmite. It has the advantages of green environmental protection, convenient operation, and high yield of finished products. However, its production cost is high and it has not yet been applied on a large scale. In the future, with technological advancement, the development speed of the boehmite industry will further accelerate.

Lithium batteries are the largest demand end for boehmite. In recent years, benefiting from national policy support, my country’s new energy vehicle industry has become more prosperous. As a new energy vehicle power battery, lithium batteries have seen increasingly strong market demand. According to statistics from the Ministry of Industry and Information Technology, my country’s lithium battery production will reach 750GWh in 2022, a year-on-year increase of more than 130%. Boehmite can be used as a coating material for lithium batteries. As the development of downstream industries accelerates, its market size continues to expand. According to the “2023-2028 China Boehmite Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, In 2022, my country’s boehmite market size will reach 370 million yuan.

High-purity boehmite is a subdivided product of boehmite. In 2022, global high-purity boehmite production will reach 117,000 tons, a year-on-year increase of 32.6%. The high-purity boehmite industry has high technical barriers. There are only two companies in the world with the production capacity of high-purity boehmite, namely Yishitong and Nabaltec of Germany. Yishitong is my country’s leading boehmite company. It focuses on the research, development, production and sales of lithium battery coating materials. At present, the high-purity boehmite produced by the company has been used in sodium-ion batteries, 4680 large cylindrical batteries and other products. .

Attracted by market prospects, the number of companies in my country’s boehmite industry continues to grow, driving competition in the market to become increasingly fierce. Anhui Yishitong Material Technology Co., Ltd., Henan Tianma New Material Co., Ltd., Zhejiang Jinguan Co., Ltd., Shenzhen Xingyuan Material Technology Co., Ltd., Shandong Guoca Functional Materials Co., Ltd., etc. are the main manufacturers of boehmite in my country. . my country’s boehmite industry is highly concentrated, with leading companies occupying a major share of the market.

Industry analysts said that boehmite has broad application prospects in many fields such as conductors, optical materials, lithium batteries, etc., along with downstream industries Rapidly developing, its market size continues to expand. As a subdivided product of boehmite, high-purity boehmite has strong market demand. At present, my country has become a major producer of boehmite, and local companies have competitive advantages in the global market.
