The application range of special alumina continues to expand and has a broad consumer market

Special alumina is an important inorganic non-metallic material. By controlling the production or processing process, its crystal phase, specific surface area, chemical purity, particle morphology, pore volume and particle size distribution are consistent with metallurgical grade aluminum hydroxide or alumina. There are large differences in aluminum-based materials.

The upstream of the special alumina industry chain is the supply of raw materials such as alumina and sodium hydroxide; the midstream is the production of different types of products, including calcined alumina, pseudo-boehmite, activated alumina, ultrafine aluminum hydroxide, and 4A zeolite etc.; downstream is widely used in ceramics, chemicals, plastics, papermaking, photovoltaic power generation and other fields.

According to the “Special Alumina Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center, Special alumina has the characteristics of wear resistance, heat resistance, low conductivity, and corrosion resistance. As special alumina production technology continues to advance and its application scope continues to expand, demand in new energy vehicles, integrated circuits, aerospace, electronic communications and other fields is also growing, driving the expansion of the special alumina market. In 2022, my country’s special alumina market will exceed 28 billion yuan.

There are two main ways to prepare special alumina: physical method and chemical method. The former is prepared by mechanical crushing method using ball mill, stirring mill equipment, etc. The production method is relatively extensive and can only change the physical properties of the product; the latter is prepared by Bayer method, sintering Production is carried out by other methods, the operation method is more complex, and the product quality is higher.

Driven by market dividends, the number of domestic special alumina production companies continues to grow, and industry competition continues to intensify. At present, the domestic special oxidation market is not highly concentrated, its independent innovation capabilities are weak, and its production technology still lags far behind the international advanced level, and there is considerable room for development. Domestic special alumina manufacturers include Henan Tianma New Materials Co., Ltd., Anhui Yishitong Material Technology Co., Ltd., Zibo Yinhan Special Alumina Co., Ltd., Shandong Guoca Functional Materials Co., Ltd., Aluminum Corporation of China, Xuanhua Chengjingrui New Materials Co., Ltd., etc.

Industry analysts said that with the continuous advancement of modern production technology and the continuous development of high-end manufacturing, special alumina is an important high-added As one of the most valuable materials, market demand will continue to grow. The advancement of science and technology will promote the continuous advancement of special alumina production technology, further improve product quality and performance, further expand the scope of application, and will have a broader consumer market. At present, the overall level of the domestic special oxidation industry still needs to be improved. Relevant production companies need to increase capital investment, update production equipment and production processes, improve production efficiency and product quality. At the same time, they must focus on brand building, actively promote products, and increase brand awareness and influence and expand their competitive advantages.
