Market Segments
Platinum based catalyst gauzes have been in use ever since ammonia is catalytically oxidized to yield either nitric acid or hydrogen cyanide. Therefore they are required in two main industrial processes: Andrussow process and Ostwald process. Both processes do convert ammonia (NH3) into precursors dedicated for a wide range of uses in several...
