The Haber-Bosch process was one of the most successful and well-studied reactions, and is named after Fritz Haber (1868–1934) and Carl Bosch (1874–1940). Haber first proposed the use of a high-pressure reaction technique. Furthermore, in order to overcome the low conversion-per-pass of ammonia, he introduced an important concept: the ...
The Haber process or the Haber-Bosch process is a chemical reaction that uses nitrogen gas and hydrogen gas to create the chemical compound ammonia. The Haber process uses temperatures ranging from 400°C to 450°C under a pressure of 200 atm. The Haber process uses a catalyst mostly made up of iron. Plus de détails

Nowadays, the main route for ammonia synthesis is the Haber-Bosch process, developed a century ago. In this process, Fe-based catalysts are usually employed at temperatures between 400 and 500 °C ...
The Bosch process is capable of producing deep features with exceptional anisotropy, etch-rate, and etch mask selectivity. This process consists of a three-step cycle: Film deposition, bottom film etching, and silicon etching. In the deposition process, a passivation film is deposited on the sidewalls and bottom surface of the trench.

The Haber-Bosch (HB) process constitutes the dominant route for ammonia production. Gaseous N 2 and H 2 react at elevated pressures (>100 bar) and temperatures (∼500°C) in the presence of an Fe-based catalyst. 8 The rate-determining step is the dissociation of dinitrogen to atomically adsorbed N species. 9 Although the reaction itself is ...
