my country’s demand for electronic grade phosphoric acid is strong and the market localization process is accelerating

Phosphoric acid, also known as orthophosphoric acid, is a ternary medium-strong acid and is widely used in medicine, food, agriculture, chemical industry, electronics and electrical fields. Electronic grade phosphoric acid refers to ultra-high purity phosphoric acid used in the electronic and electrical fields. Electronic-grade phosphoric acid has the characteristics of good stability and high purity, and can be used to produce thin-film liquid crystal displays, semiconductor microelectronics and very large-scale integrated circuits.

The preparation methods of electronic grade phosphoric acid include wet method and thermal method. Wet method refers to using phosphoric acid as the main raw material, and finally producing electronic grade phosphoric acid through processes such as precipitation reaction, adsorption, extraction, dilution, arsenic removal, and purification. This method has the advantages of green environmental protection and low production cost, and is the mainstream of electronic grade phosphoric acid. Preparation method; Thermal method can be subdivided into phosphorus oxychloride hydrolysis method, high-purity phosphorus oxidation method, phosphorus pentoxide hydration method, etc. It has the disadvantages of low finished product yield, high production cost, and many by-products, and is not suitable for large-scale production Production.

According to the “2023-2028 China Electronic Grade Phosphoric Acid Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Electronic-grade phosphoric acid is mainly used in the electronic and electrical fields, with thin-film liquid crystal displays, semiconductor microelectronics and very large-scale integrated circuits as its end products. In recent years, as the global display panel industry has gradually shifted to my country, the thin film liquid crystal display (TFT-LCD) market space has continued to expand. Against this background, my country’s electronic-grade phosphoric acid market demand is increasingly strong.

The global electronic grade phosphorus industry is highly concentrated, with leading companies accounting for nearly 50% of the market share. Belgium’s Solvay Group (SOLVAY), South Korea’s OCI Chemical Company, France’s Arkema (Arkema), and the United States’ ICL Company are world-renowned electronic-grade phosphoric acid manufacturers, and the above companies also occupy a dominant position in my country’s market.

my country’s electronic-grade phosphoric acid industry started late. There is a certain gap in technology level and product quality compared with overseas developed countries, and demand is highly dependent on imports. In recent years, with the support of national policies and the continuous improvement of the technological innovation level of local enterprises, the localization process of my country’s electronic grade phosphoric acid market has accelerated. Chengxing Co., Ltd., Jianghua Micro, Xingfa Group, Hubei Yihua, etc. are the main manufacturers of electronic grade phosphoric acid in my country.

Xingfa Group is my country’s leading electronic-grade phosphoric acid company. Its subsidiary Xingfu Electronics focuses on the research and development, production and sales of ultra-high-purity electronic chemicals. Electronic-grade sulfuric acid and electronic-grade phosphoric acid are the company’s representative products. At present, Xingfu Electronics has completed the construction of an electronic-grade phosphoric acid production line with an annual output of 30,000 tons, and its production capacity ranks among the top in my country.

          Industry analysts said that as a segmented product of phosphoric acid, electronic-grade phosphoric acid has broad application prospects in the electronic and electrical field. As downstream demand continues to grow, my country’s electronic-grade phosphoric acid market will further expand. In recent years, Chinese companies have continued to increase their investment in research and development of electronic-grade phosphoric acid preparation methods, which has accelerated the localization process in the market.
