During use, the quality of the electrode paste has three main effects on the electrode:
1. The electrode paste has high ash content, and the bonding strength of the electrode paste is poor. Where the ash content is concentrated, the bonding force is worse. This place consumes quickly and is easy to be mechanically strained and cause hard fracture. Therefore, the ash content should keep the index less than or equal to 3
2. If the softening point of the electrode paste is low, the coking value of the electrode paste after sintering is low, and the electrode strength is also poor, which is likely to cause electrode accidents.
3. The high resistivity of the electrode paste indicates that the electrode paste has a low degree of graphitization, poor conductivity, poor electrode oxidation resistance, strong electrode rigidity after firing, and the electrode is also easy to break.
