Silicon tetrachloride is an important chemical raw material with a wide range of uses, mainly including the following aspects:
Semiconductor industry
As a silicon source, it is used to manufacture high-purity polycrystalline silicon. Polycrystalline silicon is an important raw material for the production of single-crystalline silicon, and single-crystalline silicon is the core material of the semiconductor industry and is widely used in integrated circuits, solar cells and other fields.
Preparation of silicon dioxide film. In the manufacturing process of semiconductor devices, a high-quality silicon dioxide film needs to be formed on the surface of the silicon wafer as an insulating layer or gate oxide layer. Silicon tetrachloride can be decomposed and reacted with oxygen at high temperature to form a silicon dioxide film through methods such as chemical vapor deposition (CVD).
Fiber optic communication industry
It is one of the main raw materials for the production of optical fiber preforms. In the process of optical fiber manufacturing, silicon tetrachloride reacts with oxygen at high temperature to generate silicon dioxide. At the same time, the refractive index distribution of the optical fiber can be adjusted by adding other impurity elements (such as germanium, phosphorus, etc.), thereby producing optical fibers with different properties.
Chemical industry
Used in the synthesis of organic silicon compounds such as silicates, silicone rubber, silicone oil, etc. These organosilicon compounds have excellent heat resistance, water resistance, electrical insulation and chemical stability, and are widely used in many fields such as construction, automobiles, electronics, and medical treatment.
As a chlorinating agent and catalyst, it participates in a variety of organic chemical reactions. For example, in some organic synthesis reactions, silicon tetrachloride can be used as a chlorinating agent to introduce chlorine atoms into organic compound molecules; at the same time, it can also be used as a catalyst to promote the progress of some chemical reactions.
