Silicon tetrahydride has a wide range of applications and product purity is gradually improving

Silicon tetrahydride, also known as monosilane and silane, appears as a colorless gas with a foul odor at room temperature and pressure. Silicon tetrahydride is insoluble in water, insoluble in ethanol, ether, benzene, chloroform, silicon tetrachloride and other solvents. It is toxic and will cause dizziness, fever, nausea, coma and other symptoms when the human body inhales it. Silicon tetrahydride is extremely sensitive to oxygen and can ignite spontaneously in the air.

According to different purity, silicon tetrahydride can be divided into industrial grade silicon tetrahydride (purity 3-4N), electronic grade silicon tetrahydride (purity 5N and above). Industrial grade silicon tetrahydride is mainly used in glass, automobiles, construction and small-scale In integrated circuits; electronic grade tetrahydrogen silicon is mainly used in the fields of large-scale integrated circuits, chips, polysilicon, flat panel displays, and photovoltaic cells. In recent years, industries such as electronics, energy, automobiles, and semiconductors have developed rapidly, providing broad space for the development of the silicon tetrahydride market.

According to the “2022-2027 Monsilane (Tetrahydrosilicon) Industry In-depth Market Research and Investment Strategy Suggestion Report released by the Industrial Research Center 》 shows that silicon tetrahydride has a wide range of application fields. Thanks to the continued rise in downstream demand, the size of the silicon tetrahydride market continues to expand. By 2021, the global silicon tetrahydride market will reach US$470 million. It is expected that from 2022 to 2027, the global silicon tetrahydride market will be The hydrogenated silicon market will continue to grow, with an average annual compound growth rate of more than 10.0%.

The global silicon tetrahydride market is mainly distributed in North America, Europe, China and other regions. my country is the world’s largest electronics production and consumer market. The silicon tetrahydride market is growing rapidly. From 2010 to 2021, the average annual compound growth rate of my country’s silicon tetrahydride market is as high as More than 18.0%. Domestically, silicon tetrahydride suppliers mainly include Henan Silane Technology, Inner Mongolia Xingyang Technology, polyfluoropolymer Zhejiang Zhongning Silicon Industry, Zhejiang Xunding Semiconductor Materials, etc. With technological advancement, the purity of domestically produced silicon tetrahydride has been greatly improved, and some The purity of the company’s products has reached 8N level.

The synthesis process of silicon tetrahydride is divided into magnesium silicide alloy method, silicon tetrafluoride reduction method, chloromonosilane disproportionation method, etc. The purification process includes low-temperature liquefaction method, adsorption method, distillation method, preheating decomposition method, etc. With the development of downstream industries, the market demand for ultra-high purity tetrahydrogen silicon continues to rise. There are many tetrahydride silicon production companies in my country, but there are few companies with ultra-high purity tetrahydride silicon supply capacity, and market demand still relies on imports. In the international market, the main suppliers of silicon tetrahydride include Dow Corning of the United States, Linde Group of Germany, Wacker of Germany, Evonik of Germany, Shin-Etsu Chemical of Japan, etc.

Industry analysts said that silicon tetrahydride is widely used in integrated circuits, glass, automobiles, electronics, photovoltaic cells and other fields, and downstream demand Continuously rising, the industry has broad room for development in the future. There are many suppliers of silicon tetrahydride in my country, but most companies do not have the ability to supply ultra-high-purity silicon tetrahydride. In the future, domestic companies will still need to increase investment in process and technology research and development, optimize the purification process, and improve the supply capacity of ultra-high-purity silicon tetrahydride.
