摘要 |
AgSnO2-based contact materials with Bi2O3 and CuO as further metal oxide additives have already been proposed. In these, the volume fraction of metal oxide should be between 10% and 25% with an SnO2 volume fraction of >/=70% of the total oxide quantity. It is proposed to select the SnO2 mass fraction specifically in the range from 4% to 8%. The Bi2O3 mass fraction is here between 0.5% and 4%, and the CuO mass fraction is between 0.3% and 1%, the remainder being silver in each case. Contact pieces having surprisingly good electrical properties can be manufactured from such materials. |
