Technical Specifications:

Hazard Symbols: Safety Phrases S26; S36/37/39

Main Applications:

• 9N Grade (Semiconductor Grade): Serves as one of the "invisible cornerstones" of chip manufacturing. It deposits high-quality silicon dioxide (SiO₂) thin films on wafer surfaces via chemical vapor deposition (CVD), providing isolation, protection, and insulation functions. It is a critical material in the semiconductor industry supply chain.
• 6N Grade (Optical Fiber Grade): Unlike the 9N grade used in wafer processing, the 6N grade primarily serves infrastructure sectors such as optical communications. It is used in the production of key components like optical fiber preforms.
• 4N Grade: Used as an intermediate feedstock for further purification, ultimately producing 9N-grade semiconductor products for applications including memory chips and logic chip manufacturing.
