The common ethyl orthosilicate in the current market is mainly in liquid and gas forms, and is used in chemical vapor deposition, Alder, trench filling and other fields.

Ethyl orthosilicate (TEOS), also known as tetraethoxysilane, is an ethyl silicate, a silicon organic compound, an important raw material for the production of silicone resin materials, and a common high-purity silicone alcohol. Salt-based silicon source. According to the content of SiO2 in the product, ethyl silicate can be divided into several grades. The content of SiO2 in ethyl orthosilicate is about 28%, so it is also called Si-28.

Ethyl orthosilicate has a wide range of applications, and is mainly used in anti-corrosion coatings, silicone and other fields in the industry, and can also produce silicone solvents for heat-resistant coatings and chemical-resistant coatings. With the deepening of the research on ethyl orthosilicate, it is also used in the synthesis of new materials and is a commonly used precursor. In addition, electronic grade ethyl orthosilicate can also be used in the vapor deposition process.

According to the "2021-2025 China Ethyl Orthosilicate (TEOS) Industry Market Supply and Demand Status and Development Trend Forecast Report" released by Xinsijie Industry Research Center, electronic special gases are mainly used for chemical vapor deposition, ion implantation, doping Miscellaneous 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 my country's electronic special gases is about 18 billion yuan, and it is expected to reach 22.3 billion yuan by 2022, of which the integrated circuit and device fields account for It is about 45%, so the application prospect of electronic grade ethyl orthosilicate is better in the future.

The common ethyl orthosilicate in the current market is mainly in liquid and gas forms, and is used in chemical vapor deposition, Alder, trench filling and other fields. Domestic industrial-grade ethyl orthosilicate products have already been localized, and the market is in a situation of oversupply, and the industry development is in a dilemma. However, in terms of electronic grade ethyl orthosilicate, domestic substitution has not yet been achieved in China, and the market demand depends on imports.

Because electronic special gas is a dangerous chemical, 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 advanced fields, such as Huate Co., Ltd., NTU 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 more competitive in the market. At present, Jinhong Gas is still continuously improving the quality of ethyl orthosilicate products, and the products have reached 9N level. In 2021, the company successfully trial-produced electronic-grade ethyl orthosilicate products, and it is expected to achieve large-scale production in the first half of 2022. Realize domestic substitution.

Industry analysts from Xinsijie said that ethyl orthosilicate has a wide range of applications, but the application demand for industrial-grade products is saturated, the market supply and demand are oversupplied, the industry development is deadlocked, and the industry still needs to continue to explore downstream applications. With the continuous change of modern technology, the application value of ethyl orthosilicate has been explored, and the application demand in new materials and semiconductors has increased, and the application prospect of electronic grade ethyl orthosilicate is better. Before 2020, my country's electronic-grade ethyl orthosilicate market demand depends on imports. In 2021, my country will realize the trial production of electronic-grade ethyl orthosilicate, and it is expected to achieve large-scale production in 2022.
