摘要：

The behavior of the arc in a switching device operating on the vacuum principle depends strongly on the properties of the contact material used. For this reason the choice of the contact material is extremely important for the performance of the device in practical applications. A survey is given of the various types of contact materials presently produced in Europe for application in vacuum switchgear. The materials discussed comprise tungsten-base and molybdenum-base materials as well as copper-iron and copper-chromium materials. The production techniques currently practiced are described, and the resulting properties of the materials are discussed with regard to the requirements of the different types of application.
