What is a Trichlorosilane (SiHCl₃)?

Trichlorosilane (SiHCl₃) is an inorganic compound belonging to the class of silicon-based compounds. It is a colorless liquid at room temperature, with a strong pungent odor. It reacts with water to form silica (SiO₂) and hydrochloric acid (HCl), which makes it necessary to handle it carefully to avoid moisture exposure.

Trichlorosilane is primarily used in the semiconductor industry for the production of silicon wafers and is also important in the manufacture of silicone rubbers, resins, and optical fibers. It is also employed to modify the surface of silica and in various chemical surface treatments.

As a key source of silicon, trichlorosilane plays a crucial role in the production of silicon solar panels for solar power generation. Due to its high reactivity, it must be handled with caution in sealed environments to ensure safety.
