Description

Ammonium Hexafluoroniobate is an inorganic salt primarily used as a precursor in the synthesis of niobium-containing compounds and materials. Its value lies in providing a soluble and reactive source of niobium in a fluoride matrix, which is critical for advanced material fabrication. This product is essential for manufacturers and research institutions in the electronics, optical coating, and specialty catalyst industries seeking high-purity niobium inputs.

Application

• Precursor for the chemical vapor deposition (CVD) or atomic layer deposition (ALD) of niobium pentoxide (Nb₂O₅) thin films for optical coatings and capacitors.
• Starting material in the synthesis of other niobium salts and coordination complexes for catalytic applications.
• Raw material in the production of specialty glasses and ceramics where niobium is used to modify refractive index and thermal properties.
• Intermediate in the manufacturing of superconducting materials, particularly niobium-based compounds.
• Etchant or component in fluoride-based etching solutions for specialized semiconductor processing.
• Research and development of new niobium-fluorine chemistry in academic and industrial laboratories.

Quality Control

Our Ammonium Hexafluoroniobate is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets high-purity standards suitable for advanced material synthesis. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed and under anhydrous conditions, such as in a desiccator or dry inert atmosphere, to prevent decomposition. Recommended storage temperature is 15-25°C.
