Silicon tetrachloride, chemical formula SiCl₄, is a colorless or light yellow fuming liquid with a pungent odor and strong deliquescent properties. Its unique molecular structure (molecular weight 169.90) gives it a wide range of uses:

New energy field: As the core raw material of high-purity polycrystalline silicon, silicon tetrachloride helps the photovoltaic industry break through technical bottlenecks and promote the efficiency of solar cells;
High-end material manufacturing: used for the synthesis of silicates, silicone oils, high-temperature insulating paints and silicone rubbers, widely used in aerospace, electronic packaging and building fireproof materials;
Industrial innovation applications: Preparation of corrosion-resistant ferrosilicon in the metallurgical industry, as an efficient demoulding agent in the foundry industry, and even as a smoke screen agent in the military industry, showing its "all-rounder" characteristics.
