The Haber-Bosch process is still the fundamental basis for manufacturing ammonia.
The Haber-Bosch process for ammonia synthesis, which was first successfully operated here in September 1913, was the decisive step into the age of mineral fertilizers.
Today, manufacturers use the Haber-Bosch process to generate more than 100 million tons of ammonia annually for the chemical and fertilizer industries.
Chemists have long sought substitutes for the Haber-Bosch process, which works most efficiently at temperatures between 400[degrees]C and 500[degrees]C and at pressures around 400 times that of the atmosphere at sea level.
