The electronic special gas industry is developing rapidly and the market demand for tetraethoxysilane (TEOS) is becoming increasingly strong.

Tetraethoxysilane (TEOS), also known as tetraethyl silicate and ethyl orthosilicate, has a chemical formula of C8H20O4Si and is an organic compound. Tetraethoxysilane appears as a colorless and transparent liquid, soluble in gasoline, ethanol and acetone, and almost insoluble in water. Tetraethoxysilane has a wide range of uses and can be used as raw materials such as investment casting binders, heat-resistant coatings, corrosion-resistant coatings, and silicone solvents.

Silicon tetrachloride is the main raw material of tetraethoxysilane. As an inorganic silicon compound, silicon tetrachloride is widely used in many fields. Driven by market demand, my country’s silicon tetrachloride production continues to grow. In 2021, my country’s silicon tetrachloride production will reach 257,000 tons, a year-on-year increase of 9.6%. In terms of price, due to the continued increase in demand from downstream industries and the imbalance between supply and demand, the price of silicon tetrachloride in my country continues to run at a high level. In 2021, the average market price of silicon tetrachloride in my country reached 5,691.2 yuan/ton, a year-on-year increase of 8.9%. Raw material prices continue to rise, resulting in increasing production costs for tetraethoxysilane.

According to the “2022-2026 Tetraethoxysilane (TEOS) Industry In-depth Market Research and Investment Strategy Suggestions Report》shows that the preparation method of tetraethoxysilane is mainly silicon tetrachloride method, using ethanol and silicon tetrachloride as the main raw materials, carrying out esterification reaction at normal temperature and pressure, and then going through distillation, cooling, decolorization, and filtration and other processes to finally obtain tetraethoxysilane. The silicon tetrachloride method has the advantages of flexible operation and low production cost, and is suitable for large-scale production. However, this method is prone to producing hydrogen chloride gas and causing environmental pollution. In recent years, green and environmentally friendly processes represented by the silicon powder method have gradually replaced the silicon tetrachloride method as the mainstream preparation method for tetraethoxysilane.

The electronic specialty gas industry is the main demand end for tetraethoxysilane in my country. Tetraethoxysilane is mainly used in chemical vapor deposition processes, and silicon dioxide deposited films are its end products, which can protect semiconductor components. Benefiting from the increasing prosperity of the semiconductor industry, the market demand for electronic specialty gases continues to grow. In 2021, my country’s electronic specialty gas market will reach 22.67 billion yuan, a year-on-year increase of 11.2%. Driven by the rapid development of downstream industries, my country’s tetraethoxysilane market space continues to expand.

Dow Corning of the United States, WACKER of Germany, Evonik of Germany, and ShinEtsu of Japan are world-renowned manufacturers of tetraethoxysilane. Xinhan New Materials and Zhongcheng Chemical are the leading tetraethoxysilane companies in my country.

Industry analysts said that tetraethoxysilane has excellent performance and is widely used in many fields. The strong market demand has brought great benefits to the development of the industry. Huge opportunity. my country’s tetraethoxysilane preparation process has matured. Benefiting from the support of national environmental protection policies, green and environmentally friendly processes are gradually realizing large-scale production. Driven by the technological innovation of leading companies, the size of my country’s tetraethoxysilane market will continue to expand.
