Product Description
It is typically observed as a white crystalline powder or granular substance that remains entirely odorless to the senses. Exhibiting a distinct combination of salty and cool taste profiles, this compound demonstrates notable hygroscopic characteristics, readily absorbing moisture from the surrounding environment. With a defined density measuring 1.5274 grams per cubic centimeter, it demonstrates excellent solubility in water, a property that becomes increasingly pronounced with rising temperatures. Specifically, its solubility shows a marked and consistent increase as the thermal environment is elevated. The compound possesses a melting point set at 338 degrees Celsius, at which temperature it undergoes a unique physical transformation: rather than simply melting, it simultaneously undergoes sublimation, transitioning directly from the solid phase to the gaseous state without passing through the liquid intermediate phase. This thermal behavior underscores its unique physical properties and distinguishes it within its class of compounds.

Application
Ammonium chloride plays a crucial role in the metal refining process by facilitating the elimination of impurities from metals. For example, during the refining of zinc, ammonium chloride reacts with specific impurity elements within zinc, like iron. This reaction results in the formation of chlorides. Under particular temperature and condition combinations, these chlorides exhibit distinct volatilities or solubilities. Consequently, through operations such as distillation and filtration, the impurities can be effectively separated, thereby enhancing the purity of the zinc.
When exposed to elevated temperatures during a fire incident, industrial-grade ammonium chloride undergoes endothermic decomposition at approximately 338°C, a process that initiates with the dissociation into (NH3) and hydrogen chloride (HCl) gases. This thermal breakdown is critical for fire suppression: the released hydrogen chloride acts as a chemical flame inhibitor by diluting oxygen concentrations in the combustion zone, thereby disrupting the fire's oxygen-dependent chain reaction. Concurrently, the gas contributes to thermal quenching by absorbing heat from the fire source, while the endothermic nature of the decomposition itself-absorbing approximately 33.5 kJ/mol-significantly reduces the temperature of the surrounding substrate, slowing the rate of heat transfer and preventing further ignition.
Industrial-grade ammonium chloride is an important component in the production of fire retardants. For instance, it can be blended with substances like boric acid to manufacture fireproof coatings. When confronted with high temperatures during a fire, industrial-grade ammonium chloride undergoes decomposition, generating hydrogen chloride gases. These gases are capable of diluting the oxygen content in the air, thereby exerting a flame-retardant effect. Simultaneously, the decomposition process of ammonium chloride absorbs heat, which is also beneficial for reducing the temperature of the surrounding environment and retarding the spread of the fire.In summary, industrial-grade ammonium chloride's utility in fire retardants stems from its integrated thermal, chemical, and physical properties: endothermic decomposition for heat absorption, gaseous byproducts for oxygen dilution, and hygroscopicity for evaporative cooling. These characteristics, when combined with compatible co-additives, enable the creation of robust fire protection systems that address the complex challenges of modern fire safety across industrial, commercial, and residential sectors.
