The electrode materials commonly used in varistors are conductive paste, inorganic salt and metallic materials.Conductive slurry materials include precious metal slurry and base metal Slurry. based on the characteristics of various electrode materials, there are many methods to prepare varistor electrode, including slurry method, electroless plating, thermal spraying and cold spraying.
Our Silver paste is medium temperature sintering type Paste.due to the strong electrical conductivity and oxidation resistance of silver, metal can be directly welded on the surface of silver, so the electrode of varistors is usually made of silver paste.

Application
The varistors,components.Considering the technical requirements, the electrode paste used in chip components plays an important role in capacitance, dielectric loss and resistance value of the capacitor. The electrode paste used for chip elements requires proper viscosity, fineness, sintering temperature, good fluidity and uniformity. The noble metal powder plays a decisive role in the properties of slurry. The development and production of noble metal powder with excellent performance promote the further development of chip components.
