Ostwald Process for Producing Nitric Acid. The Ostwald process has many well-known uses in both the industrial and health field Through the Ostwald process, nitric acid is commonly used in fertilizers and pharmaceuticals, and because of its chemical reaction with some compounds, it is used in rocket fuel and explosives like trinitrotoluene (TNT).

The Haber process is used because it is the most energy efficient and economically favourable process currently used. The process involves combining hydrogen gas (H2), which was processed by steam reforming, and further refined by the Water-gas shift reaction, and nitrogen gas from the air (N2), of which is 78% N2, in a ratio of 3:1.
