What conditions are there to make ammonia?

Ammonia (NH3) can be produced through several methods, with the most common being the Haber-Bosch process. This method requires high temperatures (around 400-500°C) and high pressures (150-300 atm), along with iron-based catalysts, to combine nitrogen (N2) from the air and hydrogen (H2) typically derived from natural gas. Other methods include the thermal decomposition of ammonium salts and the reaction of alkali with ammonium salts, but these are less common for large-scale production.
