The Ostwald process works by converting ammonia into nitric acids in two stages. First Stage The first stage involves oxidizing oxygen by heating at a temperature range of 780 to 950 °C (1436 to 1742 °F) and pressure of 1.4 MPa (14 atm). This reaction is done in the presence of a 10-percent rhodium platinum gauze catalyst.
