Ag/Mo materials with typically 50-70 wt% molybdenum are usually produced by the powder metallurgical infiltration process <xr id="fig:Micro structure of Ag Mo 35 65"/> (Fig. 2.137) <xr id="figtab:Physical Properties of-Contact Materials Based"/> (Table 2.36)''. Their contact properties are similar to those of Ag/W materials <xr id="tab:Contact and Switching Properties of Contact Materials Based on Silver – Tungsten (SIWODUR), Silver–Tungsten Carbide (SIWODUR C) and Silver Molybdenum (SILMODUR)"/> (Table 2.37). Since the molybdenum oxide is thermally less stable than tungsten oxide the self-cleaning effect of Ag/Mo contact surface during arcing is more pronounced and the contact resistance remains lower than that of Ag/W. The arc erosion resistance of Ag/Mo however is lower than the one for Ag/W materials. The main applications for Ag/Mo contacts are in equipment protecting switching devices <xr id="tab:Contact and Switching Properties of Contact Materials Based on Silver – Tungsten (SIWODUR), Silver–Tungsten Carbide (SIWODUR C) and Silver Molybdenum (SILMODUR)"/> (Table 2.38).
