Uses and Properties of Ammonium Nitrate

Chemical Structure and Properties
Ammonium nitrate is an inorganic salt with the chemical formula NH4NO3. It is a white crystalline solid and is highly soluble in water. Its molecular structure consists of NH4+ cation and NO3- anion. It belongs to the larger class of nitrogen-containing compounds known as nitrates. Ammonium nitrate is chemically stable at room temperature but it decomposes when heated to produce nitrogen, oxygen and water. Its decomposition temperature is around 210°C. However, in presence of impurities like metal carbides or acids, it can explode at much lower temperatures.

Use as Fertilizer
As a fertilizer, ammonium nitrate is one of the most commonly used nitrogen-containing fertilizers globally. It provides nitrogen, a primary nutrient necessary for plant growth, in the nitrate form which can be readily absorbed by roots of plants. Around 60-70% of the total ammonium nitrate produced worldwide is used for fertilizer applications in agriculture. Farmers prefer it due to its high nitrogen content of 33.5% and solubility properties which allow quick absorption by soil and plants. While using ammonium nitrate as fertilizer, safety precautions must be followed to avoid explosion risks from overheating or contamination.

Use in Mining Operations
Another major end-use of Ammonium Nitrate is in explosives and blasting applications in mining and construction industries. Due to its chemically unstable nature when heat is applied, ammonium nitrate provides the oxidizing effect required in explosives. When mixed with fuels like gas oil or aluminum powder, it forms blasting explosives used in quarrying, tunneling and demolition works. Such explosives possess high detonation velocity and allow efficient fragmentation of rock material. Ammonium nitrate based commercial blasting agents account for over 70% of the total industrial explosives   globally.

Use in Pyrotechnics and Propellants
Small amounts of ammonium nitrate are also used in pyrotechnic formulations along with fuels and binders for applications like road flares, fireworks and smoke bombs. Due to its oxidizing and gas releasing properties upon combustion, ammonium nitrate mixtures can be designed to burn brightly with colored flames. It further finds usage as an oxidizer component in solid rocket and airbag propellants where, combined with fuels, it enables controlled burning to produce thrust. However, regulatory approvals must be obtained for manufacturing and handling of ammonium nitrate based pyrotechnic compositions.

Safety Concerns and Incidents
While ammonium nitrate is highly useful, it also possesses inherent explosion hazards which require precautionary handling and storage. Breach of such safety norms have resulted in devastating accidents and loss of lives in history. Major ammonium nitrate disaster incidents include the Texas City explosion of 1947 where a ship carrying ammonium nitrate cargo caught fire causing massive detonation killing almost 600 people. In 2004, Ryongchon disaster in North Korea occurred due to explosion of large ammonium nitrate stockpile resulting in 161 casualties. The 2011 Tianjin explosions in China involved ignition of over 700 tons of improperly stored ammonium nitrate explosives. The 2020 Beirut explosions that shocked the world was caused due to ignition of improperly stored 2,750 tons of confiscated ammonium nitrate. Such occurrences emphasize the importance of regulating ammonium nitrate transportation, storage and usage as per safety guidelines.

Production Processes
There are three major production processes used commercially for manufacturing ammonium nitrate on large scale:

1. Acid-base reaction process: In this process, ammonia gas is passed through dilute nitric acid solution generating ammonium nitrate crystals on reaction and evaporation.

2. Direct oxidation of ammonia process: Here, anhydrous liquid ammonia is oxidized by air in presence of platinum or palladium catalyst producing ammonium nitrate vapor which is then cooled and condensed.

3. Ammonium sulfate nitration process: Involves neutralizing ammonium sulfate with nitric acid forming ammonium nitrate crystals and sulfuric acid as a byproduct.

Irrespective of the process route, high purity ammonium nitrate product suitable for fertilizer and explosive applications can be obtained on large scale through continuous operation, evaporation and crystal harvesting steps. Manufacturing facilities must also comply with strict safety norms due to explosive nature of ammonium nitrate.

Applications
Ammonium nitrate has emerged as a highly useful nitrogenous compound playing a crucial role worldwide as nitrogen fertilizer, mining explosive and oxidizing propellant. However, its inherent explosive properties require cautious handling, transportation, storage and disposal as mandated by regulations. With evolving technologies, alternative safer oxidizers are also being developed for replacement in some explosive applications. Overall, as long as the explosive risks are addressed properly, ammonium nitrate will continue serving humanity through diverse fields including agriculture, construction and space research.
