Pronunciation: [ˈamɒnə͡l] (IPA) 
Ammonal is a term used for an explosive compound made from ammonium nitrate and aluminum powder. It is pronounced /ˈæmənəl/ and spelled with double "m" and "n" to reflect the pronunciation of the word. The "a" sounds like the "a" in "cat," the first "o" sounds like the "o" in "hot," and the last "a" sounds like the "a" in "pal." Ammonal is commonly used in mining, demolition, and military applications due to its explosive properties.
Ammonal is an explosive mixture composed primarily of ammonium nitrate (NH4NO3) and powdered aluminum (Al). It is commonly used as a blasting agent or explosive in mining, quarrying, and construction industries due to its high explosive power and stability.
The composition of ammonal usually consists of about 80-90% ammonium nitrate and 10-20% finely powdered aluminum. This combination creates a highly effective explosive material with desirable properties, such as low sensitivity to shock, friction, or impact, and a relatively high detonation velocity.
Ammonal is typically found in a granulated or powdered form, and its components are thoroughly mixed to ensure a homogeneous blend. The aluminum powder acts as a fuel and provides additional oxygen when reacting with ammonium nitrate, enhancing the explosive power.
Upon detonation, ammonal undergoes a rapid exothermic reaction, generating a large amount of gas and heat, resulting in an explosive shockwave. This shockwave can be utilized to break rocks, demolish structures, or propel projectiles.
However, despite its effectiveness, ammonal poses certain safety risks due to its explosive nature. Proper handling, storage, and transportation protocols need to be followed to prevent accidental detonation and to ensure the safety of workers and the general public.
The word "Ammonal" is derived from the combination of two words: "ammonium" and "aluminum".
Ammonium refers to a chemical compound containing the element nitrogen in its ammonium ion form (NH4+). It is commonly used in explosives due to its high reactivity and ability to release large amounts of energy.
Aluminum, on the other hand, is a metallic element known for its lightness, strength, and malleability. It is often used in the production of various materials, including explosives, due to its ability to react exothermically with other substances.
The term "Ammonal" was coined to describe an explosive material that includes both ammonium compounds and aluminum powder. This combination enhances the explosive power of the substance, making it more effective in various applications.
