The level of volatile compounds in electrode paste can significantly affect its usage. Here is our analysis of the potential impacts, highlighting why it’s critical to control volatile content within a specific range to avoid adverse outcomes.
When volatile content is too high, it can lead to the following problems:
Difficulty in sintering, resulting in poor strength and a tendency to break easily (soft breakage).
High shrinkage, resulting in low strength and potential for hard breakage.
Rapid oxidation, causing fast consumption of electrode paste.
Layered sintering that leads to irregular shapes, making it challenging to lower the electrode, which can also break easily.
Reduced load capacity when lowering the electrode, slower load increases, affecting production rates.
When volatile content is too low, it can lead to these issues:
Early sintering, resulting in poor strength and an increased risk of hard breakage.
Inadequate adhesion, leading to poor strength and a higher risk of hard breakage.
High contact resistance between the electrode and the conductive jaws, affecting energy consumption and reducing the lifespan of the conductive jaws.
When comparing the above outcomes, it is clear that excessive volatile content has more severe consequences than low volatile content. Therefore, it is crucial to maintain the volatile content of electrode paste within a specified range.
