my country’s high-purity alumina market is in short supply and local companies have huge development potential

High-purity alumina refers to alumina with a minimum purity of 99.99%. Its chemical formula is AL2O3 and its appearance is white micro-powder. High-purity alumina has the characteristics of stable chemical properties, odorless, corrosion resistance, high purity, heat resistance, wear resistance, etc., and is widely used in high-tech fields and modern industry.

The preparation process of high-purity alumina includes alkoxide hydrolysis method, carbonization method, metal aluminum hydration method, hydrothermal method, aluminum ammonium sulfate method, double aluminum method, etc. The alkoxide hydrolysis method uses metal alkoxide and high-purity aluminum foil as raw materials. After hydrolysis, hydroxide and hydrate precipitates are obtained, and finally high-purity alumina is obtained through high-temperature calcination. The alkoxide hydrolysis method has the advantages of environmental protection, good product stability, high production efficiency, and is suitable for large-scale production. It is currently the main method for the world’s leading companies to prepare high-purity alumina. However, due to the high production cost of the alkoxide hydrolysis method, it has not been widely used in our country.

According to the “2022-2027 High Purity Alumina Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, High-purity alumina has a wide range of applications, including automotive sensors, refractory materials, wear-resistant materials, fluorescent materials, catalysts, high-pressure sodium lamp tubes, functional ceramics, sapphire, etc. Driven by the rapid development of downstream industries, my country’s high-purity alumina market demand continues to grow. In 2021, my country’s demand for high-purity alumina will reach 27,000 tons, a year-on-year increase of 19.70%. With continuous breakthroughs in production technology, the application fields of high-purity alumina in my country will continue to expand, and the demand will further increase.

5N high-purity alumina refers to the preparation of ultra-high-purity alumina with a purity exceeding 5N, which is the mainstream product in the high-purity alumina market. 5N high-purity alumina is the main raw material for the production of LED substrate sapphire single-chip wafers. In recent years, my country’s 5N high-purity alumina market has continued to expand. In 2021, my country’s 5N high-purity alumina market will reach 1.89 billion yuan, a year-on-year increase of 13.20%.

There are many high-purity alumina manufacturers in my country, including Zibo Honghe Chemical, Dalian Hailan Optoelectronic Materials, Jiyuan Xiling Electronics, Xuancheng Jingrui New Materials, Shandong Guocera Functional Materials, Shanghai Yiming Materials, etc. The above companies have high-purity alumina The annual production capacity exceeds 2.0 thousand tons. As a well-known supplier of high-purity alumina powder and 5N alumina powder products in my country, Shanghai Yiming Materials has advanced high-purity alumina preparation technology and multiple invention patents. In 2021, Shanghai Yiming Materials’ high-purity alumina production capacity exceeded 7.0,000 tons , ranking first in the country.

Industry analysts said that as a new material, high-purity alumina has a wide range of downstream applications, and in recent years, with the release of downstream market demand , my country’s high-purity alumina production capacity continues to increase. There are many high-purity alumina manufacturers in my country, but the development of the industry is still in its infancy, and there is still a certain gap between production technology and overseas advanced levels. As a result, my country’s high-purity alumina market is in short supply and highly dependent on imports.
