The development of ethyl orthosilicate industry is at a deadlock. Electronic grade ethyl orthosilicate has good development prospects.

Ethyl orthosilicate (TEOS), also known as tetraethoxysilane, is a kind of ethyl silicate and silicon organic compound. It is an important raw material for the production of silicone resin materials and the most common high-purity silicone. Alkoxide silicon source. Ethyl silicate can be divided into multiple brands according to the SiO2 content in the product. The SiO2 content in ethyl orthosilicate is about 28%, so it is also called Si-28. Ethyl orthosilicate has a wide range of applications. In industry, it is mainly used in anti-corrosion coatings, silicone and other fields. It can also produce silicone solvents for heat-resistant coatings and chemical-resistant coatings. As the research on ethyl orthosilicate continues to deepen, it has also been applied in the synthesis of new materials and is a commonly used precursor. In addition, electronic grade ethyl orthosilicate can also be used in vapor deposition processes.

According to the “China Tetraethyl Orthosilicate (TEOS) Industry Market Supply and Demand Status and Development Trend Forecast Report 2021-2025” released by the Industrial Research Center shows that electronic special gases are mainly used in chemical vapor deposition, ion implantation, doping and other processes. Driven by the development of the semiconductor industry, the demand for electronic special gases in my country continues to rise. In 2020, the market size of electronic special gases in my country will be approximately 180 billion billion, and is expected to reach 22.3 billion yuan by 2022, of which the integrated circuit and device fields account for about 45%. Therefore, the application prospects of electronic grade tetraethyl orthosilicate are good in the future.

The common ethyl orthosilicate in the current market mainly comes in two forms: liquid and gas, and is used in chemical vapor deposition, Alder, trench filling and other fields. Domestic industrial-grade tetraethyl orthosilicate products have long been localized, and the market is experiencing an oversupply situation, and the industry has entered a dilemma. However, in terms of electronic grade ethyl orthosilicate, domestic substitution has not yet been achieved, and market demand relies on imports.

Since electronic special gases are hazardous chemicals, the import procedures are complicated and the cycle is long, which affects the development of downstream industries. In recent years, with the support of domestic policies, my country’s leading electronic and special gas companies have deployed in high-end fields, such as Walter Co., Ltd., Nanda Optoelectronics, Jinhong Gas and other companies. Jinhong Gas has advanced tetraethoxysilane production technology, and its products are used in new energy, coatings and other fields, and are relatively competitive in the market. At present, Jinhong Gas is still continuously improving the quality of ethyl orthosilicate products, and the products have reached the 9N level. In 2021, the company successfully trial-produced electronic-grade ethyl orthosilicate products, and is expected to achieve large-scale production by the first half of 2022. Realize domestic substitution.

Industrial analysts said that ethyl orthosilicate has a wide range of applications, but the application demand for industrial-grade products is saturated, and there is excess supply and demand in the market. Phenomenon, the development of the industry has reached a deadlock, and the industry still needs to continue to explore downstream application areas. With the continuous change of modern technology, the application value of ethyl orthosilicate has been discovered, and the demand for applications in new materials and semiconductors has increased. Electronic grade ethyl orthosilicate has good application prospects. Before 2020, my country’s electronic-grade ethyl orthosilicate market demand relied on imports. In 2021, my country will achieve trial production of electronic-grade ethyl orthosilicate, and it is expected to achieve large-scale production in 2022.
