Boron Trifluoride (BF3) Gas

Boron Trifluoride (BF₃) Gas | Industrial & High Purity Specialty Gas

Supplier: Wenzhou Yingyue New Materials Co., Ltd.

1. Product Overview

Boron Trifluoride (BF₃) is a colorless, non-flammable, highly corrosive specialty gas with a pungent, suffocating odor. As a professional manufacturer and exporter of high-purity boron-based gases, we supply BF₃ gas covering industrial grade, 2.5N (actual 3N) grade and 4N (ultra-high purity) grade, with purity ranging from 99.6% to 99.999%. Produced with advanced purification technology and strictly tested per GB/T 39708-2020 standards, our BF₃ meets international export specifications. With standardized CGA330 valve cylinders and global compliance, we serve organic chemical, semiconductor, electronic and metal processing industries worldwide.

3. Purity Grade & Impurity Control

We offer gradient purity BF₃ gas with strict impurity control, supported by third-party test reports for stable quality:

All batches undergo rigorous quality inspection to ensure batch consistency and compliance with industrial and high-end manufacturing requirements.

4. Physical & Chemical Properties

Boron Trifluoride is a typical electron-deficient Lewis acid with unique chemical reactivity and strict handling requirements:

• Solubility: Highly soluble in cold water, concentrated sulfuric acid and most organic solvents; reacts with water to form H₂O·BF₃ complex and fluoroboric acid (HBF₄).

• Stability: Stable under dry, sealed conditions; decomposes under high temperature or strong moisture to release toxic fluorine-containing byproducts.

• Reactivity: Reacts violently with oxidants, strong bases and alcohols; forms stable adducts with Lewis bases (N, P, O-containing compounds).

• Safety Notes: Non-flammable but highly corrosive and toxic; forms corrosive fumes in moist air. Requires explosion-proof storage and corrosion-resistant equipment for handling.

5. Packaging & Shipping

We provide GB/DOT compliant packaging for global markets, supporting small-batch trial orders and large-volume bulk supply:

• Standard Cylinders: 47L/440L steel cylinders with corrosion-resistant 316L stainless steel CGA330 valves, ensuring airtightness and leak prevention.

• Bulk Supply: ISO tanks for large-scale industrial demand, complying with international dangerous goods transportation standards.

• Compliance: All packages meet UN 1008 and GB/T 39708-2020 standards; complete SDS and batch test reports provided for customs clearance.

6. Main Applications

Boron Trifluoride is a critical specialty gas for modern chemical and electronic industries:

1. Organic Synthesis Catalysis: Core catalyst for esterification, polymerization and alkylation reactions in fine chemicals, pharmaceuticals and agrochemicals.

2. Semiconductor & Electronics: Key doping source for ion implantation in semiconductor wafers and integrated circuits; raw material for optical fiber manufacturing.

3. Metal Processing: Flux for magnesium alloy welding and boronizing agent for steel surface treatment, preventing oxidation and improving corrosion resistance.

4. Specialty Material Synthesis: Raw material for producing boron halides, elemental boron and high-purity boron-containing compounds.
