Ammonia is a compound of nitrogen and hydrogen.


Ammonia has many diverse uses as a precursor or intermediate product in the production of nitrogenous materials; as a refrigerant in cooling systems; as a NOx reduction agent; and as a hardening agent for metal surfaces.

Ammonia is available as a technically pure standard product and as a chemically pure specialised product. It is available in liquid form and is delivered in railway tank wagons.
