Description

Boron-11 Trifluoride (¹¹BF₃) is a stable isotope-labeled gaseous compound of significant industrial and research importance. Its primary value lies in its enriched Boron-11 isotope, which offers a low neutron capture cross-section, making it critical for applications requiring minimal neutron interference. This high-purity specialty gas is essential for the semiconductor, nuclear, and advanced materials sectors, where precise isotopic composition and chemical purity are paramount for process reliability and product performance.

Application

• Semiconductor Manufacturing: Used as a p-type dopant source in chemical vapor deposition (CVD) and ion implantation processes for silicon and other semiconductor materials.
• Nuclear Industry: Employed in neutron detection systems and as a filling gas in radiation counters due to the favorable properties of the Boron-11 isotope.
• Chemical Synthesis: Acts as a powerful Lewis acid catalyst in organic synthesis, particularly for polymerization, alkylation, and isomerization reactions.
• Isotope Labeling & Research: Serves as a precursor for synthesizing other Boron-11 labeled compounds for use in medical research, diagnostics, and tracer studies.
• Advanced Materials: Utilized in the production of boron nitride and other high-performance ceramics and composites.
• Analytical Chemistry: Used in mass spectrometry and NMR spectroscopy as a reference or reagent gas.

Quality Control

Our Boron-11 Trifluoride is produced and handled under stringent quality management systems. Each batch is analyzed to verify critical parameters including isotopic enrichment (¹¹B), chemical purity, and impurity profiles. Certificates of Analysis (COA) detailing gas chromatography (GC), FTIR, and mass spectrometry results are provided to ensure traceability and compliance with your technical specifications.

Storage

Preserve in a tightly closed, approved high-pressure cylinder or container, protected from light. Store in a cool, well-ventilated area away from heat, ignition sources, and incompatible materials such as strong bases and organic compounds. Cylinders should be secured upright with valve caps in place. Due to its highly volatile and gaseous nature, storage areas must have adequate ventilation and leak detection.
