Ammonium Chloride 25% (NH4Cl, CAS 12125-02-9) solution is a clear, mildly acidic salt solution with a specific gravity of about 1.07. Ammonium chloride is used as a galvanizing and soldering flux, in metal finishing, dry-cell batteries, fertilizers, and as a clay stabilizer in oilfield fracturing and completion fluids. It is corrosive to many metals, so non-metallic storage tanks are commonly used. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the most economical tank material for Ammonium Chloride 25%, rated Excellent. Polypropylene, PVDF (Kynar®) and nylon are also rated Good or better. Avoid Hastelloy hardware.
