High-purity sulfuric acid is in short supply and demand will continue to grow in the future

High-purity sulfuric acid (also known as electronic-grade sulfuric acid, ultra-pure sulfuric acid) is an ultra-clean and high-purity reagent. It is a key basic chemical reagent developed with the development of microelectronics technology and the electronics industry. It is one of the eight chemicals commonly used in the semiconductor industry. One of the reagents. At present, high-purity sulfuric acid is widely used in the semiconductor field and the assembly and processing of very large-scale integrated circuits. During the cleaning and etching process of silicon wafers, it can effectively remove impurity particles, inorganic residues and carbon deposits on the wafers. The purity and cleanliness of high-purity sulfuric acid have an important impact on the yield, electrical performance and reliability of electronic components.

Currently, around the world, Japan, Europe and the United States (mainly the United States and Germany) master the core technology of high-purity sulfuric acid. There are only a few companies in the world that can produce high-purity sulfuric acid on a large scale, such as BASF and Mitsubishi Chemical. However, as emerging countries represented by China continue to make breakthroughs in the research and development of high-purity sulfuric acid production technology and begin small-scale mass production, the monopoly positions of these companies are constantly being shaken, and the competition pattern of the global high-purity sulfuric acid market is gradually changing. , market competition has also become more intense.

According to the “China High Purity Sulfuric Acid Industry Market Monitoring and Future Development Prospects Research Report 2022-2026” released by the Industrial Research Center In recent years, with the rapid development of high-end integrated circuits, the market for high-value-added high-purity sulfuric acid has been in short supply. Due to technical limitations, the number of enterprises in China’s high-purity sulfuric acid industry is small and generally small in scale. As a result, China’s high-purity sulfuric acid production capacity and output are generally small. Moreover, due to the short commissioning time of most devices, production is unstable and capacity utilization is generally low. On the low side.

Industrial researchers believe that in the future, with the continuous upgrading of downstream market development and the continuous improvement of product quality, the quality requirements for high-purity sulfuric acid will also The demand for high-purity sulfuric acid products of G3, G4 and even G5 grades will increase accordingly, and their proportion in the overall demand structure of high-purity sulfuric acid will increase. In addition, with the improvement of product quality requirements and the diversification of application fields in the downstream market, the demand standards for high-purity sulfuric acid products will become more refined, and the development of customized standard production is not ruled out. From the perspective of consumption area, China will become the main production chain distribution area of ​​the global microelectronics industry in the future. Semiconductor, LCD panel and other industries will develop rapidly, driving the growth of consumer demand for high-purity sulfuric acid.
