1. Performance and application
Grade 7N silicon tetrachloride, as a high-purity silicon source, serves as a crucial precursor for the preparation of semiconductors, optical fibers, and optoelectronic materials. It can be used to generate high-purity silicon or silicon dioxide films through processes such as chemical vapor deposition, which are applied in the manufacturing of high-end devices such as transistors, integrated circuits, and optical fiber preforms. In the silicone industry, it is also a core raw material for the synthesis of silicate esters, silanes, silicone oils, and other silicon-based polymers. Its derivative products are widely used in coatings, rubber, sealants, high-temperature resistant insulating paints, and other fields. Additionally, it can be used to manufacture smoke screens, special glass, and optical components, meeting the special needs of both military and civilian applications.

2. Packaging and Storage
This product is packaged in a specially made polyethylene plastic drum with a standard specification of 25kg per drum. Customized packaging can also be provided according to specific customer needs. When storing, it should be placed in a cool, dry, and well-ventilated environment with an ambient temperature not exceeding 30℃. Direct sunlight and proximity to heat sources should be strictly avoided. During storage, the container must be kept sealed to prevent contact with moisture in the air, which could affect product performance.

3. Safety protection
This product reacts violently when exposed to water, generating silicic acid and hydrogen chloride, and simultaneously releasing a highly irritating gas. This gas exhibits strong corrosive and irritating effects on the skin, eyes, and respiratory tract. Therefore, when handling this product, it is essential to wear protective gear resistant to chemical corrosion (such as nitrile or fluororubber gloves, protective glasses or face masks, and acid-alkali resistant protective clothing). The entire operation should be conducted in a fume hood or local exhaust system. If necessary, a positive pressure self-contained breathing apparatus should also be equipped and used to ensure operational safety.
