Question

aluminium by habers

Answer 1

The commercial synthesis ofammonia began, not with the peaceful use of fertilizer, but with the necessities of war. In the early years of this century, Germany understood that any war that it might have with England would, at least initially, result in the blockade of critical war materials from abroad. The most important of these resources was quano, manure from seagulls that roosted along the coast of Chile. This quano was rich in nitrates and was the basis of the German manufacture of explosives. The problem was that it had to be shipped by the tanker-load across the Atlantic and past patrolling British warships.

But during this period, the chemistry of ammonia synthesis was being explored by the German chemists Fritz Haber and Walther Bosch who found that it was possible to produce ammonia from nitrogen and hydrogen by the process:

N2 + 3 H2  2 NH3

Answer 2

It's ammonia not aluminum according to me
Ammonia is manufactured by Haber's process.

The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first half of the 20th century. The process converts atmospheric nitrogen (N2) to ammonia (NH3) by a reaction with hydrogen (H2) using a metal catalyst under high temperatures and pressures.
Before the development of the Haber process, ammonia had been difficult to produce on an industrial scale with early methods such as the Birkeland–Eyde process and Frank–Caro process all being highly inefficient.

Although the Haber process is mainly used to produce fertilizer today, during World War I it provided Germany with a source of ammonia for the production of explosives, compensating for the Allied trade blockade on Chilean saltpeter.
