The Haber process is a technique used for the production of ammonia, which is an essential compound used for fertilizers. There are several synonyms for the Haber process, including Haber-Bosch process, ammonia synthesis, nitrogen fixation, and synthetic ammonia production. The Haber-Bosch process derives its name from its inventors, Fritz Haber and Carl Bosch, who were awarded the Nobel Prize in Chemistry in 1918 for their work. The process involves the reaction between nitrogen and hydrogen gases over an iron catalyst to produce ammonia. This process has revolutionized the industrial production of fertilizers, and has made it possible to feed billions of people around the world.
