Ammonium Chloride - Manufacturers, Suppliers and Exporters

Ammonium Chloride NH4Cl , is a clear white water-soluble crystalline salt. The solution is mildly acidic in nature. The substance occurs in volcanic regions, forming on volcanic rocks near fume-releasing vents. The crystals deposit directly from the gaseous state, and tend to be short-lived, as they dissolve easily in water. Ammonium chloride is prepared commercially by reacting ammonia (NH3) with hydrogen chloride (HCl). It is also available as a by-product of Soda Ash Plant and some other chemical processes.

• Ammonium chloride is sold in blocks ( bars or briquettes ) at hardware stores for use in cleaning the tip of a soldering iron and can also be included in solder as flux. A principal use has been as a fluxing agent for hot dip galvanizing of steel and in the refining of zinc. It provides fluxing action by reacting with molten zinc to form a stable melt.
• It is used as it is or in compound fertilizer. It has higher concentration of Nitrogen than ammonium sulphate. Nitrification is less rapid than in urea or ammonium sulphate and this means N losses are lower. Although it is better known as rice fertilizer, it has been tested and used on other crops like wheat, barley, sugarcane, maize, fiber crops etc. Of particular note is the use of this fertilizer on palms; increasing the yield of Copra per tree.
• Other uses include a feed supplement for cattle, in hair shampoo, in textile printing, in the glue that bonds plywood, as an ingredient in nutritive media for yeast, in cleaning products, and as cough medicine. Its expectorant action is caused by irritating action on the bronchial mucosa. This causes the production of excess respiratory tract fluid which presumably is easier to cough up.
• Found in nature and also produced industrially, it has other important uses too. These include lowering the melting temperatures of certain metals for manufacturing processes, and as a fertilizer, anti-caking agent and ingredient in personal care products and pharmaceuticals.
• Other uses include electrolyte for plating baths and/or batteries; fertilizer, personal care product formulations, pharmaceuticals etc.
• Ammonium chloride is used as an expectorant, diuretic and systemic acidifying agent. It is used in the treatment of severe metabolic alkalosis, to maintain the urine at an acid pH in the treatment of some urinary-tract disorders or in forced acid diuresis.
• Ammonium salts are an irritant to the gastric mucosa and may induce nausea and vomiting.
• Electroplating Use: These days, there are three primary types of acid zinc plating baths: straight ammonium chloride, straight potassium chloride and mixed NH4Cl/KCl. Acid zinc plating systems have several advantages over alkaline cyanide and alkaline non-cyanide zinc plating systems except that in acid zinc plating, the electrolyte is extremely corrosive.
• Ammonium chloride zinc plating: The ammonium chloride bath is the most forgiving of the three major types of acid zinc plating because of its wide operating parameters.
• Dry Cell or Batteries: It is a component of dry cell batteries, little storehouses of energy that power so many of our electrical devices.
• Galvanizing, Soldering and Tinning Fluxes: It is used in fluxes for galvanizing, soldering and tinning.
