| The catalytic gauze of platinum alloys is indispensable in the oxidation of ammonia for the production of nitric acid. The gauze must possess of high conversion rate of ammonia, low platinum-loss rate, good corrosion-resistant, high strength at high-temperature, good adhesion-resistant and poisoning-resistant in the production process. Focusing on how to improve the service performance of the catalytic gauze, the development from pure platinum to multicomponent platinum alloys of the catalytic material and the development from weaving to knitting in the gauze weaving method were reviewed. |
