{{Short description|Chemical process for producing nitric acid}}
The '''Ostwald process''' is a [[chemical process]] used for making [[nitric acid]] (HNO<sub>3</sub>).<ref name=Ull>{{cite encyclopedia |author=Thiemann, Michael |author2=Scheibler, Erich |author3=Wiegand, Karl Wilhelm |year=2005|encyclopedia=Ullmann's Encyclopedia of Industrial Chemistry|publisher=Wiley-VCH|place=Weinheim|doi=10.1002/14356007.a17_293|chapter=Nitric Acid, Nitrous Acid, and Nitrogen Oxides|isbn=978-3-527-30673-2}}</ref> The Ostwald process is a mainstay of the modern [[chemical industry]], and it provides the main raw material for the most common type of fertilizer production.<ref>{{Cite book |last1=Kroneck |first1=Peter M.

This method is preferred over other methods of nitric acid production, in that it is less expensive and more efficient.<ref>{{Cite web |title=Ostwald Process |url=https://unacademy.com/content/upsc/study-material/chemistry/ostwald-process/ |access-date=2024-09-05 |website=Unacademy |language=en-US}}</ref>
