Product Name:Ammonium fluoride
English Name:Ammonium fluoride
CAS No.:12125-01-8
Aliases:Ammonium fluoride
Molecular Formula:NH4F
Physical Properties:White leaf-like or needle-like crystals, hygroscopic, forming hexagonal columnar crystals after sublimation. Density 1.009 g/cm³ (25°C). Freely soluble in water (100 g/100 mL at 0°C) and methanol, sparingly soluble in ethanol, insoluble in acetone and liquid ammonia. Aqueous solution is acidic. Decomposes into ammonia and hydrogen fluoride when heated or in hot water. Melting point approximately 198°C (sublimation).
Uses:Used as a glass etching agent, preservative, disinfectant, and textile mordant. Used as a chemical polishing agent for metal surfaces and in the extraction of rare elements. Used as an analytical reagent and masking agent, and for etching titanium and silicon wafers; oxidizing agents such as nitric acid or chromic anhydride must be added during titanium etching to prevent hydrogen embrittlement.
Technical Specifications:
Formula: NH4F, Molecular weight: 37.04
Assay: ≥98.0% (analytical grade)
Density: 1.009 g/cm³ (25°C)
Melting point: approximately 198°C (sublimation)
Solubility: freely soluble in water and methanol, sparingly soluble in ethanol
