Description

Ammonium Fluoride is an inorganic salt of hydrofluoric acid, widely recognized for its role as a versatile fluorinating and etching agent. Its primary commercial value lies in its ability to introduce fluoride ions into various substrates and selectively remove silicon dioxide, making it a critical processing chemical in high-tech manufacturing. This compound is essential for industries involved in electronics, glass treatment, and metal surface preparation, where precise chemical reactivity is paramount.

Application

• Semiconductor & Microelectronics Manufacturing: Used as a selective etchant for silicon dioxide (SiO₂) on silicon wafers and in glass passivation processes.
• Glass & Ceramics Industry: Employed in frosting, etching, and polishing of glass surfaces, as well as in the production of opalescent glass.
• Metal Treatment & Surface Finishing: Acts as a component in metal cleaning solutions and pickling agents to remove oxides from metal surfaces.
• Chemical Synthesis & Catalysis: Serves as a fluorinating agent in organic synthesis and as a catalyst or precursor in various chemical reactions.
• Wood & Textile Preservation: Utilized as an ingredient in wood preservatives and flame retardants for textiles.
• Analytical Chemistry & Laboratory Reagent: Used in analytical procedures and as a standard or reagent in laboratory settings.

Quality Control

Our Ammonium Fluoride is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We provide comprehensive quality assurance, with product specifications meeting the requirements for industrial and technical grade applications. A Certificate of Analysis (COA) detailing purity, assay, and impurity levels is available for every batch upon request, supporting your quality and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C.
