Trichlorosilane Reduction Process

Trichlorosilane Reduction Process

The principle is to reduce high purity trichlorosilane with high purity hydrogen on the high purity silicon core at about 1100℃ to generate polycrystalline silicon deposited on the silicon core. On the basis of the traditional Siemens process, the improved Siemens process is equipped with a

SiHCl3

Trichlorosilane Market Risen Strongly

Trichlorosilane (TCS or SiHCl3) is generated as follows within a high temperature, pressurized reactor: Si + 3 HCl ➡ SiHCl3 + H2 ，Si + 3 SiCl4 +2 H2 ➡ 4 SiHCl3 .The TCS is then sent to the CVD (Chemical Vapor Desposition) reactor. In the Siemens process, high-purity silicon "starter" rods or

Trichlorosilane Risen Trend

Gradual Strengthening Of Trichlorosilane Industry Concentration

Since May 2022, trichlorosilane has been sustained upward by the downward trend in silicon metal prices. In the long term, a number of photovoltaic promotion policies have been introduced at home and abroad, and the global photovoltaic industry is expected to continue to grow. From the point of

Synthesis Methods Of Trichlorosilane

Synthesis Methods Of Trichlorosilane

At present, there are two main synthesis methods of trichlorosilane: one is the traditional synthesis method, that is the silicon chloride method. The other is hydrolyzation of tetrachloride. At present, the mainstream method of polysilicon production is the modified Siemens method, using

Photovolatic Upstream Product

Trichlorosilane Competitive Industry

Trichlorosilane is a higher degree of marketization, competition is more adequate industry. The price of industrial products is easily affected by upstream raw materials and downstream demand. Trichlorosilane production raw materials are mainly industrial silica powder and liquid chlorine, if the

Trichlorosilane Production Process

Introduction To Trichlorosilane Industry Growth

Silane coupling agent product price growth is very obvious, compared with the same period last year growth of 118%. Upstream raw material trichlorosilane price rise, silane products for the high price operation provides a strong support. Reporters learned that trichlorosilane is mainly used in the

Package

Photovoltaic Grade Trichlorosilane In Short Supply

With the rapid growth of downstream PV demand, photovoltaic grade trichlorosilane continues to be in short supply. The application of PV grade trichlorosilane in the production of polysilicon includes a one-time requirement for the first commissioning, which accounts for about 20% of the total

Trichlorosilane Industry Chain Map

Trichlorosilane Industry Chain Map

Trichlorosilane is mainly used in the manufacture of polysilicon and silane coupling agents, among which polysilicon is the most important downstream application area of trichlorosilane, accounting for 32% of the consumption in 2021, and silane coupling agent consumption accounted for 25%. The
