在简要回顾历史后，阐述了对银氧化物的要求。将这些要求与材料的技术接触性能进行了比较，讨论了大量不同的银金属氧化物在·焊接时、·腐蚀时、·大量开关操作后闭合触点的温升、·断裂时的腐蚀、·磁场中的电弧运动、·电弧熄灭等方面的要求。第三组分，即低浓度给药材料的影响也包括在内。接下来是对最重要的制造方法的描述。从内部氧化和烧结开始，以及基于这两种技术的方法，生产阶段以图表形式表示。大量实验研究的结果揭示了银金属氧化物的应用范围及其与其他材料相比的局限性。展望未来，研究表明，如果发展继续下去，在未来5-10年内，Ag/CdO可能会被本质上更环保的材料Ag/SnO 2所取代。
After a short historical survey, the requirements for silvermetal oxide are explained. These requirements are compared with the technical contact properties of the materials, which are discussed for a large number of the most different silver-metal oxides with regard to · welding on make, · erosion on make, · temperature rise of closed contacts after a large number of switching operations, · erosion on break, · arc movement in the magnetic field, · arc extinction. The effect of a third component, dosing materials in low concentrations, is also included. This is followed by a description of the most important methods of manufacture. Starting from internal oxidation on the one hand and sintering on the other, as well as methods which are based on both technologies, the stages of production are represented in diagrammatic form. The results of a large number of experimental investigations lead to the ranges of application of silver-metal oxides and their limits compared with other materials. Looking to the future, it is shown that Ag/CdO will probably be replaced, if the development continues, by the essentially more environmentally acceptable material Ag/SnO 2 during the next 5-10 years.
