Electronic grade hydrochloric acid has a wide range of applications in various fields of our lives, such as medicine, chemical industry, semiconductor, large-scale integrated circuit and other industries. Electronic grade hydrochloric acid is mainly used for high temperature gas phase etching of silicon and arsenic before epitaxial growth to clean sodium ions. In addition, high-purity hydrochloric acid is also used in metal surface chemical treatment, mixed gas for laser, film production and carbon fiber surface treatment.
At present, most of my country's high-purity electronic grade chemicals rely on imports. With the rapid development of the domestic electronics industry towards high integration, high uniformity and high integrity, the requirements for electronic grade hydrochloric acid, which is widely used in the vapor phase polishing of monocrystalline silicon and the corrosion of epitaxial frames, are becoming higher and higher.
Status of domestic hydrochloric acid market:
1. Most domestic hydrochloric acid companies set prices according to the market, and determine the output according to the market. The market supply is sufficient and the operating rate is unstable;
2. The market of synthetic hydrochloric acid is greatly affected by the market of upstream liquid chlorine, which rises and rises, and falls and falls;
3. It is difficult to balance chlor-alkali. At present, domestic chlor-alkali enterprises are in a state of adjustment and are transforming to the development model of chlor-alkali supplementation. The price adjustment of chlor-alkali products is an inevitable phenomenon;
4. The selling price of electronic grade hydrochloric acid is high, and most of them rely on imports.
With the rapid development of the national photovoltaic industry and new energy, the demand for electronic grade hydrochloric acid is increasing. In the past, my country mostly relied on imports, and in recent years many technological breakthroughs have been made. Electronic grade hydrochloric acid products have high added value and rich profits. They are fine chemicals with high technical content.
At present, only a few manufacturers produce electronic grade hydrochloric acid. The electronic grade hydrochloric acid produced by Chongqing Chuandong Chemical Group has a purity of over 99.999%. The content of organic impurities such as HCl, H20 and metal ions in hydrochloric acid is also required to be lower and lower. With the development of photovoltaic and new energy and new industries, the demand for electronic grade hydrochloric acid will also continue to grow. It is believed that the hydrochloric acid industry will enter a structural adjustment period of eliminating outdated production capacity and expanding the electronic grade hydrochloric acid industry.
