| 中文摘要: |
| 铂合金催化网是氨氧化法制备硝酸不可缺少的催化剂。生产中要求铂网氨转化率高、铂耗低、耐腐蚀性强、高温强度高、抗粘结和抗毒性强。围绕如何提高催化网的使用性能，评述了铂合金催化网材料制造从一元金属到多元合金的发展，以及织网方法从编织到针织的发展。 |
| 英文摘要: |
| 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. |
