Item:266029007623Ammonium Chloride -1 kg NH4CI - Au,Pd,Pt. Ammonium chloride is an inorganic compound with the formula NH4Cl and a white crystalline salt that is highly soluble in water. Solutions of ammonium chloride are mildly acidic. Ammonium chloride is used as a flux in preparing metals to be tin coated, galvanized or soldered. It works as a flux by cleaning the surface of workpieces by reacting with the metal oxides at the surface to form a volatile metal chloride. For that purpose, it is sold in blocks at hardware stores for use in cleaning the tip of a soldering iron, and it can also be included in solder as flux. Ammonium Chloride (AKA Sal Ammoniac) is often used in the recovery process of platinum (Pt) gold (Au) Palladium (Pd) from catalytic converters. It is combined with water and used as a wash solution to precipitate metal dissolved in an aqua regia solution.
