Description

Boric-11B Acid CAS NO 13813-78-0 is the isotopically enriched form of boric acid, where the boron atoms are predominantly the stable isotope Boron-11. This high-purity material is critical for applications requiring precise control over nuclear properties and minimal neutron absorption. It is an essential precursor in the semiconductor, nuclear, and advanced materials industries. Key users include manufacturers of neutron detectors, dopants for semiconductor production, and researchers in nuclear chemistry and isotopic labeling.

Application

• As a precursor for Boron-11 enriched boron nitride (BN) and other ceramic materials with tailored thermal and electrical properties.
• In the production of neutron detection devices and shielding materials, where low neutron capture cross-section is paramount.
• As a dopant source in semiconductor manufacturing, particularly for silicon and compound semiconductors, to modify electrical characteristics.
• For isotopic labeling in nuclear magnetic resonance (NMR) spectroscopy and research to study reaction mechanisms.
• In the synthesis of specialty boron-based chemicals and pharmaceuticals requiring isotopic purity.
• As a starting material for chemical vapor deposition (CVD) processes to deposit thin films.

Quality Control

Our Boric-11B Acid is produced under stringent quality management systems. Each batch is analyzed to ensure high isotopic enrichment (typically >99 atom % ¹¹B) and chemical purity. Certificates of Analysis (COA) are provided, detailing isotopic abundance, assay, and impurity profiles via techniques like ICP-MS and titration. We support compliance with relevant industry standards for high-purity and isotopic chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and maintain purity.
