Product description:Colorless leaf or needle crystal, hexagonal columnar crystal after sublimation. Easy deliquescence. solubility Soluble in water, acidic aqueous solution. Soluble in alcohol, insoluble in acetone and ammonia.1. Ammonium fluoride solution can be used as a cleaning agent, corrosion inhibitor, with mud acid buffer solution, MOS grade is mainly used for medium and large scale integrated circuit, BV Ⅲ grade is mainly used in the production of IC. 2. Used for the extraction of rare elements. In the ground glass industry used as glass etching agent, also used for metal surface chemical polishing agent, wine disinfectant, preservative and fiber mordant. 3. The fluoride ammonium and nitrate can be used in some chemical polishing of aluminum. Ammonium fluoride can also be used for titanium and silicon etching, etching need to add in the etching liquid for titanium oxide material such as nitric acid or chromium anhydride to prevent hydrogen embrittlement.
