Haber's Process for the Manufacture of Ammonia & Its Uses

Haber–Bosch process or just Haber process is basically one of the most efficient and successful industrial procedures to be adopted for the production of ammonia. German chemists Fritz Haber along with his assistant in the 20th century developed high-pressure devices and catalysts to carry out the process on a laboratory scale.

Introduction to Ammonia Production | AIChE

Haber finally developed a process for producing commercial quantities of ammonia, and in 1906 he was able to achieve a 6% ammonia concentration in a reactor loaded with an osmium catalyst. This is generally recognized as the turning point in the development of a practical process for the production of ammonia in commercial quantities.
